A 21-year-old woman with a rare disease died when staff at a hospice failed to replace part of her breathing tube, an inquest has heard.

Emily Bushaway "turned blue" after part of her ventilator, known as a whisper valve, was seemingly discarded at Helen & Douglas House in Oxford.
Her father Mark Greener said he noticed the part was missing when he came to take her home.
Coroner Darren Salter recorded a narrative verdict.
He concluded staff had not been suitably trained in invasive ventilation and were unfamiliar with the valve.
He said the serious risks were not adequately highlighted in the patient's care plan, so her accidental death was contributed to by neglect.
The coroner also recommended the hospice improve areas of training in ventilators.
Ms Bushaway, who was from Letchworth, was having several days of respite care in May 2016.
She was diagnosed at six years old with the neuro-degenerative condition Niemann-Pick disease type C.
Mr Greener told the inquest her ventilator was attached directly to a plastic breathing tube connected to her windpipe.
Its whisper valve needed washing and changing daily, and allowed Ms Bushaway's body to get rid of carbon dioxide.
Mr Greener explained the ventilator was hooked up to a screen which displayed a "no-flow" alarm.
The court heard that on 14 May its message log showed the alarm had been triggered three times in 13 minutes.
Shortly after, Mr Greener arrived to find his daughter in her wheelchair looking "awful" with blue fingernails and lips.
He told the inquest: "They [the staff] were woeful. I walked in there and they were standing there doing nothing."
A post-mortem examination found Ms Bushaway died of "severe respiratory compromise due to a failure of the ventilator function".
The family's lawyer, Tim Deeming, said: "Such a tragic, avoidable death has understandably shocked the whole family. Whilst Helen & Douglas hospice can provide supportive care, on this occasion they have let the family down though such systemic failures."


Vulnerable Scottish families could gain more than £2.3m a year if a Glasgow child poverty scheme is extended, according to the Scottish Greens.

The party said more than 5,000 financially vulnerable families could benefit if the scheme was rolled out across the rest of Scotland.
The Healthier Wealthier Children project focuses on advising families on how to maximise their income.
NHS Scotland has been running the scheme since October 2010.
As of September 2014, it had provided assistance leading to more than £9m of financial gain for families, according to the NHS.
Under the scheme, health workers and midwives help families apply for benefits they are entitled to, but do not claim because of a lack of understanding or a hesitancy to approach the benefit authorities.
Scottish Greens health spokeswoman Alison Johnstone said: "The Healthier Wealthier Children project in Glasgow has helped vulnerable families gain an average of over £1,000 and after pushing her in parliament, the health secretary [Shona Robison] has already agreed to roll this out, but we need to start seeing some action now."
She added: "The healthier, wealthier children campaign has been an outstanding success.
"Between its launch in October 2010 and May 2016, a total of just more than 11,000 referrals to money advice services were made across the NHS Greater Glasgow and Clyde area, with a total annual financial gain of £11.6m.
"Some families gained as much as £3,400, which obviously has a massive impact on their quality of life, so the faster this can be rolled out, the better for Scotland's 5,000 financially vulnerable families."
Health Secretary Shona Robison said: "I very much welcome the contribution that is made by health visitors, midwives and others through the healthier, wealthier children project, which we funded.
"We must ensure that everybody - NHS staff and their partners in income maximisation - sees tackling health inequalities as part of their role.
"I can commit to supporting the roll-out of the project; we can build it in through the workforce plans.
"The multidisciplinary model for primary care with link workers and others lends itself well to tackling health inequalities and to income maximisation."


Battaash eased to sprint victory with a brilliant display in the King George Stakes at Glorious Goodwood.

The Jim Crowley ridden three-year-old impressed in his Group Two debut, having dominated from the front in last month's Coral Charge at Sandown.
The 9-2 shot finished two and a quarter lengths clear of 9-4 favourite Profitable, who was second.
Marsha was in third, but two-time winner of the race Take Cover ended fourth despite a quick start.
BBC horse racing correspondent Cornelius Lysaght
The feeling that a new star is emerging amongst the leading British-trained sprinters continues, as the very speedy Battaash positively swept aside his rivals again.
Perhaps the most surprising thing about this easy success - which followed two straightforward wins at Sandown, one of them smashing the course record time - was his odds.
Conventional wisdom beforehand went that the rain-softened going wouldn not suit. But Battaash - described by his trainer as a "bull in a china shop" aged two - has matured in all areas, including his ground preference, it seems.


The Open University is to close seven regional centres in what it says is an attempt to streamline student support.

The OU says affected staff would need to relocate, or take voluntary redundancy or early retirement.
The OU says services to students will not be reduced or withdrawn and the institution remains committed to operating across the whole of the UK.
But unions described the plans as catastrophic and warned that 500 jobs across the seven centres were at risk.
Under the proposals, OU offices in Bristol, Birmingham, Cambridge, Gateshead, Leeds, London and Oxford would close.
The university said these were not offices that were used predominantly as teaching centres.
The new structure would see existing offices in Belfast, Cardiff, Edinburgh, Milton Keynes, Manchester and Nottingham retained, as well as a small sub-office in Dublin.
The OU said the centres in Milton Keynes, Manchester and Nottingham would expand, allowing them to give greater investment in student support and "deliver improvements that are not possible in the current configuration of 13 offices".
"These improvements include quicker response times, more proactive support to those students who need help during their studies and longer opening hours," a statement from the university said.
"The larger centres will help us provide seamless support for students from first contact through to completion of studies."
The OU says the new structure will be in place by February 2017 at the earliest.
A final decision will be made by the university's council in late November. If approved, a period of consultation with unions will follow.
Peter Horrocks, vice-chancellor of the OU, said students' experience of the university had not been limited by geography for some time.
"This is a difficult decision and I fully recognise the impact it will have on many of our staff, but we cannot afford to stay still.
"This recommendation, if approved, would allow us to enhance student support in a way that's simply not possible in our current office network, and offer our students the sort of support they expect and deserve."
But the University and College Union (UCU) warned that thousands of current and future students could be affected by the move, which could see the removal of services, such as careers counselling, study advice and support for disabled students.
OU UCU branch president Pauline Collins said the OU was respected all over the world for the way it brought quality higher education to a wide range of people.
"At the core of that mission are its dedicated regional staff who provide essential support to thousands of students and their tutors.
"Axing almost 500 staff across seven centres would be catastrophic and decimate the Open University's ability to provide the kind of local support that students need.
"We are unconvinced by the university's talk of staff relocating, especially as this will mean hours spent in the car or on the train just trying to get to and from work."
The OU has almost 200,000 students, with many combining their study with employment and other commitments.


Stadium safety expert Paul Scott has made new claims about pressure allegedly put on him behind the scenes over the Casement Park project.

He told a Stormont committee that Gaelic Athletic Association (GAA) official Ryan Feeney told him he could persuade senior police officers to drop concerns on safety at the new stadium.
Mr Feeney is a member of the Northern Ireland Policing Board.
He has said the claims are completely untrue.
He has consulted lawyers about taking action.
The Police Service of Northern Ireland (PSNI) has also said it came under no such pressure.
The claims were made at a meeting of the Culture, Arts and Leisure (CAL) committee at Stormont on Thursday.
Mr Scott, who works for Sport Northern Ireland, was asked by William Humphrey of the DUP about a report on Casement Park drawn up by the safety technical group, which Mr Scott chairs.
The report outlined concerns about emergency exiting arrangements at the planned 38,000-capacity stadium, and concluded they were not fit for purpose.
Mr Humphrey asked Mr Scott if any pressure was exerted to try to change the report.
Mr Scott told the committee: "We were advised that the design team, the GAA, DCAL (Department of Culture, Arts and Leisure) had access to high-ranking police officers and that they would be able to get the police report changed."
Mr Humphrey then asked who had told that to Mr Scott.
"Ryan Feeney advised us and also Carl Southern," Mr Scott said.
"It was saying: 'Well, look, if we get the police to change their views, then the other emergency services will follow suit. You guys are going to be left on your own and you will look very foolish.'"
Ch Insp Anthony McNally from the PSNI was also at the meeting. He intervened immediately.
He said: "I was involved in conversations from last summer through to now with the GAA where they did come in to speak to senior police in relation to Casement, and I can certainly say there was never, through any of those conversations, any effort to put pressure on the police to change the report."
Mr Feeney later issued a statement, saying: "I emphatically deny the allegations by Paul Scott.
"Paul Scott and I never had a conversation, at any stage, on the PSNI's role or involvement in the Casement project.
"I attended a series of meetings with the PSNI on Casement and every one of these meetings involved other GAA officials and design team members.
"I would ask the BBC to note the comments of chief inspector McNally at the CAL committee regarding this matter.
"I have already taken legal advice and intend to take immediate action on this matter."
Mr Southern used to work for the Department of Culture, Arts and Leisure, but no longer works there.
It is believed he is now working in England.
The BBC is making efforts to try to contact him, to inform him of Paul Scott's remarks and seek a response.
Another safety officer working on the Casement Park project also appeared before the DCAL committee on Thursday.
Laura Strong claimed she was ridiculed and laughed at after expressing concerns about the proposed new stadium.
She said she was left feeling "quite shaken" after a meeting at a Belfast hotel last year with officials from the GAA, the stadium design team and civil servants from DCAL.
Ms Strong told MLAs that she and her Sport NI colleague Mr Scott faced a "barrage of abuse" when they outlined their concerns about emergency exiting arrangements at the proposed stadium.
She said: "We were subjected to ridicule, abuse, felt patronised and considered that efforts were being made to humiliate us.
"People were openly laughing at us … I left feeling quite shaken."
Mr Scott claimed the GAA later apologised.
He said: "One of the representatives of the GAA phoned me the next morning to say 'Paul, I'm so sorry about what you had to put up with yesterday, it was just uncalled for'.
"And another member of the GAA said similar things."
Mr Scott and Ms Strong said the Casement meeting in question took place at the Wellington Park hotel in south Belfast on 17 June last year.


Hosting the Open golf championship in St Andrews brought £140m into the Scottish economy, an independent assessment has found.

The income included £88m of spending by tourists visiting Scotland for the tournament, along with £52m in marketing benefit to a global audience.
The Scottish government said this was the biggest ever impact of a golf tournament in the UK or Ireland.
The Sheffield Hallam University study said 93,000 people attended at Open.
Total spectator admissions were 237,024, with more than a quarter of spectators coming from overseas.
The direct windfall is almost double what was brought in by the 2010 tournament, also in St Andrews, which had an impact of £47.5m.
Commenting on the news, First Minister Nicola Sturgeon said the "excellent figures" showed that the connection between golf and its "spiritual home" in Scotland was "as strong and productive as ever".
She said: "It is always a special homecoming for players and spectators alike when The Open returns to the Old Course - they have the opportunity to experience not only one of the finest courses in the world, but also take in such a stunning setting on the Fife coast.
"Hosting such events is a tremendous opportunity to showcase Scotland internationally as the perfect stage for events as well as generating spend for local businesses, restaurants and hotels, and the wider Scottish economy."


One of Mozambique's richest women, Valentina Guebuza, has been shot dead by her husband in a case of domestic violence, police say.

Zofino Muiuane was arrested after Mrs Guebuza was killed at their home in the capital, Maputo, police said.
Mrs Guebuza, 36, is the daughter of Mozambique's ex-President Armando Guebuza, who ruled from 2005 to 2015.
She married Mr Muiuane at a lavish ceremony, attended by regional leaders, in 2014.
While police said the shooting was a case of domestic violence, they also said they were still investigating the motive.
Mr Muiuane, a manager at Mozambique's first mobile phone company M-Cel, has not yet been charged.
The killing has shocked many people and it is rare to hear of domestic violence in wealthy and politically linked families in Mozambique, says the BBC's Jose Tembe in Maputo.
Mrs Guebuza became one of Mozambique's wealthiest businesswomen during her father's presidency, our correspondent adds.
Business magazine Forbes listed her in 2013 as one of the 20 most powerful women in Africa.
She headed a family-owned investment holding company, Focus 21 Management & Development, which has interests in sectors ranging from telecommunications to mining.
Focus 21 has a significant stake in Chinese Pay TV Company StarTimes' operations in Mozambique.


Plaid Cymru is "actively considering" whether to seek a coalition with Labour, leader Leanne Wood has said.

Plaid is cooperating with Labour's minority government from opposition.
Ms Wood said there was "ongoing discussion" about whether it was better to formally share power, with members genuinely torn over the "dilemma".
But Plaid Cymru AM Neil McEvoy said that the agreed official position was against coalition and "reports to the contrary surprise me".
The South Wales Central AM is due to speak at a fringe meeting at Plaid Cymru's conference on Saturday in opposition to joining Labour in the Welsh Government.
But Ms Wood told BBC Wales that her party was "actively considering this all the time".
"This question of how best Plaid Cymru can play a role that protects Wales' best interests," she said.
"We have taken the view thus far that we can use this minority government situation to get as many of our manifesto commitments through and to influence other aspects like legislation, like the debate on Brexit.
"But we have also taken the view that the government deserves opposition as well and scrutiny and we can't afford to leave it just to the parties of the right to do that."
"That could change as time goes on, but as things stand at the moment the compact has served us well and the fact that we've managed to deliver Â£119m worth of our commitments in the budget shows that it's working quite well for us at the moment."
The compact was the agreement Plaid made with Labour to allow Carwyn Jones to return as first minister, a week after he and Ms Wood were deadlocked in a vote to take the top job.
The two parties have a "good working relationship", she said, but there remained big differences between them over Brexit.
Ms Wood added: "I think people [in Plaid] are genuinely torn between the two views of whether or not they [Labour] are so bad at governing that we should be in there helping them, or they are doing such a bad job they need to be held to account with a strong opposition. This is the dilemma.
"I think that's the conundrum for most members."
Simon Thomas, who represented Plaid Cymru in the compact negotiations, stressed what he saw as the success of the arrangement, while accepting that some in his party were pushing for a place in government.
The Mid and West Wales AM said: "Though there's always been, and always will be in Welsh politics, discussion about coalitions we have an actual relationship with the Welsh Government which I want to see work because I think it's delivered in the budget process.
"I think we need to maintain that going forward as the most appropriate method for challenging the government and holding them to account whilst, of course, not being in coalition with them."
Plaid will use its conference in Llangollen to demonstrate t secured concessions in this week's draft budget including more money for higher education and medical training.
As a result, Plaid plans to abstain on voting on the budget, which will allow the Labour-led Welsh Government's spending plans to pass.
However, Ms Wood said it was "Labour's budget" and "not our programme".
The Conservatives said the budget deal was proof Plaid was propping up Labour.
Former Plaid AM Lord Elis-Thomas quit the party last week, saying it was not serious about working with Labour.
Other leading figures in the party are known to be in favour of working more closely with Labour.
A Tory spokesman called Ms Wood's comments about coalition "knee-jerk stuff from a leader plagued with insecurity, seeking at all costs to avoid further mutiny from her members by rushing to do a budget deal with Labour, and in the process, attempting to publicly undo the damaging comments inflicted by Dafydd Elis-Thomas".
"In her indecision to form a coalition with Labour, her ambition to reverse the will of the Welsh people after the EU referendum, and her failure to manage her members, Leanne Wood's leadership is painfully on the wane," the spokesman added.


The former chief executive of the animal charity, the USPCA, Stephen Philpott has been arrested by police investigating an allegation of fraud.

A 52-year old woman was also arrested in Newry on Wednesday.
"A complaint was made to police in April and, as a result of our enquiries, two people were arrested this morning," Det Ch Insp Ian Wilson said.
"They are being questioned at Banbridge police station."
In a statement, a USPCA spokesperson said: "We became aware of suspected irregularities in our organisation and passed the information on to the PSNI for investigation.
"We will continue to offer every assistance to the PSNI whilst they carry out their inquiries.
"We thank our members and the public for their continued support at this time."


A pre-season game between Leyton Orient and Gillingham had to be abandoned after a serious injury to Gills midfielder Lee Martin.

The 29-year-old, who joined the League One side from Millwall earlier this summer, suffered a suspected dislocated or broken left ankle.
He was hurt after landing awkwardly 13 minutes before full-time, and the game was called off soon afterwards.
"Our thoughts are with Lee," said Gillingham manager Justin Edinburgh.
"We hope that he makes a quick recovery," Edinburgh added of the former Manchester United youngster, who had come on at half-time in place of Bradley Dack.
First-half goals from Jordan Bowery and Jay Simpson had put League Two side Orient 2-0 up when the game was abandoned.
Martin is the third Gillingham player to be injured during pre-season, with defender Bradley Garmston and midfielder Aaron Morris both out of action with knee injuries.


Wales' biggest house builder Redrow has reported a rise of 23% to £250m in its pre-tax profits.

The Flintshire-based firm said sales were "very encouraging" after figures released on Tuesday showed revenue rose 20%.
A spokesman said they were confident it would be "another year of significant progress for Redrow".
Chairman Steve Morgan told the Good Morning Wales programme the business had seen "no effect" from Brexit.
He said demand for homes was "stronger than it's ever been".
However, he also reiterated comments he made last year that fewer houses may be built in Wales because of the increasing costs of regulations.


One of the government's flagship home ownership programmes ends on Saturday, amidst both praise and criticism.

The Help-to-Buy Mortgage Guarantee scheme is likely to have helped more than 100,000 individuals or couples buy a home.
The Council of Mortgage Lenders said it had worked "exceptionally well", making mortgages more available when it started in October 2013.
However Shelter has argued that the scheme helped to push up house prices.
Under the programme, borrowers were able to get a mortgage with just a 5% deposit. If those borrowers were unable to make payments, the government promised to compensate the lender.
But around 30 banks or building societies now offer similar high loan-to-value loans, so the Bank of England declared in September that the scheme is no longer necessary.
The Help-to-Buy Equity Loan scheme - which is only available on new-build homes - will remain on offer until 2020, in England alone.
Have you used this scheme? If so, email us at haveyoursay@bbc.co.uk.
So far the Mortgage Guarantee scheme has cost the taxpayer a relatively small amount of money.
Up to 30 September, only two home-owners had defaulted on their mortgages, meaning that the Treasury has had to pay out just Â£17,411 to compensate mortgage lenders.
In the long run it has set aside a potential Â£12bn to pay out in compensation.
With interest rates at record lows, default rates have also been minimal.
However when interest rates eventually rise, more borrowers are likely to default on mortgage payments, so the Treasury may have to pay out more.
The guarantee on such mortgages - and thus taxpayers' liability - lasts for seven years after they are taken out.
As a result the Treasury won't know the final cost of the scheme until June 2024.

A pilot who died along with his family when the plane he was flying crashed was "poor under pressure", his instructors have told investigators.

Philip Garvey, 56, his wife Ann, 55, and their children Emily, 23, and Daniel, 20, died when their plane came down in Somerset in November 2015.
They were flying from Surrey to Devon.
The Air Accidents Investigation Branch (AAIB) said it was possible Mr Garvey tried to manually start landing while the autopilot was still on.
Mr Garvey had taken off from Fairoakes Airport, close to the family home in Woking, and was heading to Dunkeswell Aerodrome.
The AAIB's report said it was an overcast and rainy day and all planned flights at Dunkeswell had been cancelled because of the weather.
Several witnesses told investigators they heard a sound like a plane doing "aerobatics" before the Piper Malibu Mirage appeared from the clouds and hit the ground near Churchinford, south of Taunton.
The AAIB said: "The evidence from the autopilot examination system suggested that, as the pilot turned on to the final approach and started to descend, the autopilot may not have been disengaged due to a mental lapse, incorrect button selection or a technical fault."
The plane was seen to quickly climb into cloud before coming down.
The AAIB concluded it was "unable to determine with certainty the reason for the initial rapid climb" but said attempting to override the autopilot would have caused the plane to go "nose up" as it would fight to maintain its set height.
While the aircraft could still have been controllable, it said "recovery may have been beyond his capabilities".
Mr Garvey had been a pilot since 2012 and had flown to Dunkeswell 25 times since 2013, including 14 times from Fairoaks.
His instructors told investigators he was "less able than average pilots at multi-tasking and poor at prioritising especially when under pressure".
Another instructor said Mr Garvey "would often have difficulty dealing with an unusual or unexpected condition".


With six months to go until the start of the London 2012 Olympics, the timetable is looking good for the Dorset-based sailing events.

Weymouth Bay and Portland Harbour was the first Olympic venue to be finished, a new Â£90m relief road has opened, and a marina has been built in time for the Games.
But can the area's re-invention as a marine centre of excellence replace its proud naval past?
For 150 years Portland was home to a naval base which played a crucial role during World War I and World War II.
Before defence cuts led to its closure in 1999, it had 4,500 employees, in a town of 65,000 people.
Simon Williams, head of Portland and Weymouth 2012 Operations, said the outlook for the area was much now better than originally feared.
"When the naval base first closed, we had academics predicting 16% unemployment," he said.
"It's never been anything like that.
"The main problem is we don't have the same opportunities as we did when the naval base was here, but that's why we are working with businesses in the area such as Sunseeker."
Mr Williams said he would also invite entrepreneurs to Olympic sailing events in the hope of boosting investment in the area.
Since the former naval base was sold to Portland Harbour Authority Limited (PHAL) in 1998 it has become a commercial port used by cruisers and yachts.
The former Royal Naval Air Station Portland, otherwise known as HMS Osprey, was closed in 1999, and later became the Olympic sailing academy.
Old helicopter maintenance buildings in the area have been taken over by Sunseeker, the luxury yacht maker, whereas the former Admiralty underwater weapons establishment (AUWE) has been adopted by businesses and a Â£10m business hotel.
A new marina has been built adjacent to the sailing academy, called Osprey Quay after the former naval base, in time for the Olympics.
Tourism is set to be given a boost by a Â£3m observation tower in Weymouth which will give views of the Jurassic coast on a revolving platform.
"People were predicting dire consequences when the navy moved out and the Admiralty research buildings closed down, but it's remarkable how resilient the area has been," says local historian Stuart Morris.
"The whole place could have become run down and derelict, but other things have filled the vacuum."
However, people living locally say the Olympics has created traffic problems over the past two years which have deterred tourists.
Roadworks, now completed, have been in place in Weymouth to replace roundabouts with "intelligent" traffic lights.
Dave Price runs the Molyneux Guest House and is chairman of the Weymouth Hotel & Guesthouse Leaseholders Association.
He said: "I think the Olympics have been good for Portland because we've got Osprey Quay and the relief road, but the last two years we've had traffic problems which have put people off coming here.
"No-one's seeing the influx of tourists for the Olympics that we were promised. Our bookings are down on last year."


Immigration detention should be capped at 28 days, a cross-party group of MPs and peers has recommended.

Home Office officials are failing to follow guidance that immigration detention should be used sparingly, the MPs and peers said in a report.
The group said the lack of a time limit had significant mental health costs for detainees.
The government should consider alternatives such as allowing detainees to live in the community, it said.
Current Home Office policy puts the health of detainees at serious risk, the panel added.
The All Party Parliamentary Group (APPG) on Refugees and the APPG on Migration said there were  considerable financial costs to the taxpayer because there is no time limit on detention.
It said the UK was the only country in the European Union not to have an upper time limit on detention.
The panel, which included a former cabinet minister, a former chief inspector of prisons, and a former law lord, considered evidence over eight months.
APPGs are informal cross-party groups that have no official status within Parliament.
Conservative MP David Burrowes, a member of the inquiry panel, said: "The lack of a time limit is resulting in people being locked up for months and, in some cases, several years purely for administrative reasons.
"While there is a need to properly control our borders, people who arrive by fair means or foul must also be treated with dignity and respect throughout the immigration process.
"The current system is failing to sufficiently do this and our report calls for an urgent rethink."
Mr Burrowes said the UK should follow the example of other countries where rates of detention are much lower and removal rates much higher.
Women who are victims of rape and sexual violence should not be detained, nor should pregnant women, the group recommends.
It also recommended that screening processes are improved to ensure that victims of trafficking are not detained.
Paul Blomfield, chair of the panel and Labour MP for Sheffield Central, said: "Current Home Office policy is that detention should be used as a last resort and for the shortest possible time.
"From the evidence that we heard, Home Office standard practice falls well short of this policy."
Refugee Council chief executive Maurice Wren said a "bright light" had been "shone into the darkest corners of the British immigration system and it has revealed some unpleasant secrets".
He said: "Quite simply, the British government is detaining too many people for too long.
"In the current system, asylum seekers who have done nothing wrong find themselves arbitrarily placed behind bars, on the say so of Home Office civil servants, for one primary reason: because it's politically expedient.
"Ministers must take this opportunity to pursue wholesale reform and abandon the existing structure of immigration detention which has been shown to be grossly inefficient, hugely expensive and in direct contradiction of our most cherished British values of justice, liberty and compassion."


The way the government intends to pay for its plans to allow social tenants in England to buy their homes is "extremely questionable", MPs say.

The Commons Communities Committee criticised the funding model for the right-to-buy scheme, which will see housing associations reimbursed for selling homes to tenants at discounts.
MPs say it should be paid for directly rather than via council house sales.
Ministers say it will help create a million new homeowners by 2020.
The government says it is one of a number of measures that will see 400,000 new affordable homes built by 2020-21.
The extension of the longstanding right-to-buy scheme for council-house owners to housing association tenants in England was one of the Conservatives' main manifesto pledges at last year's election.
Under the voluntary scheme, which is currently being piloted in five areas, housing associations will be expected to sell properties to tenants interested in buying them at a discount of Â£103,900 in London and Â£77,900 outside the capital.
Housing associations, which can reserve the right not to sell in certain circumstances, will retain the proceeds of sales and will be expected to build one new affordable property for every property sold on a national basis within a period of three years.
The government has said the scheme, a centrepiece of the Housing Bill currently going through Parliament, will be paid for by the sale of high-value council homes when they become vacant.
The legislation envisages that local authorities make payments to government based on the value of their housing stock, on the expectation that more expensive properties would be disposed of when falling empty.
Potential buyers must have been tenants for at least three years, the same as with council tenants.
The government says that means up to 1.3 million housing association tenants will be eligible in England. Around 500,000 housing association tenants are already eligible for some discounts. So the new scheme will extend rights to a further 800,000 tenants, and increase the discounts available.

But critics have questioned whether this will be sufficient to reimburse housing associations, amid claims the scheme could cost more than Â£11bn if everyone entitled to buy their home took up the opportunity. There are also doubts whether associations will be able to replace homes on a one-for-one basis, given the lack of suitable land and bottlenecks in the planning system.
In their report, the cross-party committee expressed concerns about what it said was a "levy" on local councils and urged the government to set out "fully costed" details of how it would be funded.
It warned that a large number of properties sold through the existing right-to-buy scheme had quickly been put on the rental market and that it might be necessary to limit the ability of housing association tenants to become private sector landlords.
It also called for safeguards to protect the amount of affordable housing in rural areas, including allowing housing associations to offer tenants "portable discounts" to purchase an alternative property to the one they live in where it was difficult to replace.
Clive Betts, the Labour MP who chairs the committee, said the success of the policy should be judged on how many new houses were built and not whether more tenants ended up owning their own home.
"We are concerned that there are a number of unresolved issues with the government's policy which could have a detrimental effect on the provision of accessible and affordable housing, particularly affordable rented property," he said.
"The government needs to set out in more detail how it will meet its target of at least one-for-one replacement of the sold homes, particularly given issues such as  the availability of land, the capacity of the building industry and the uncertainty of income from council home sales."
The scheme, which is partly designed to reverse the steady decline in home ownership levels in recent years, is currently being piloted in Norfolk, Oxfordshire, Surrey, Merseyside and a number of London boroughs.
The Local Government Association said councils could be forced to sell a minimum of 22,000 homes depending on how the government defined "high-value" and that the government should, instead, look at ways of freeing up public land for new homes.
"Councils want to help the government shift spending from benefits to bricks and support measures to help people into home ownership but we agree with the committee that the right to buy extension to housing association tenants should absolutely not be funded by forcing councils to sell off their homes," said the LGA's housing spokesman Peter Box.
The Department for Communities and Local Government said more details about the sale of vacant council houses would be set out in due course but the principle of using them to pay for new house building was the right one.
"There are billions of pounds locked up in local authority housing assets. It is only right that when they become vacant they are sold enabling the receipts to be reinvested in building new homes and supporting home ownership through right-to-buy," a spokesman said.
He added: "Anybody who works hard and aspires to own their own home should have the opportunity to realise their dream."
The Labour government in Wales is planning to abolish right-to-buy entirely while in Scotland it will be phased out by August. A separate scheme exists in Northern Ireland.


Controversial comedy The Interview is to have "a wide release" in the UK and Ireland, Sony Pictures has confirmed.

The film, the story of which involves a fictional plot to kill the North Korean leader Kim Jong-un, will be shown, in cinemas only, from 6 February.
Sony had withdrawn the film in the wake of a damaging studio cyber-attack, only to then release it in selected cinemas and make it available online in the US.
The film has now made more than $31m (Â£20.5m) from its digital distribution.
Its limited theatrical release, meanwhile, has netted its makers around $5m (Â£3.3m).
Co-written and co-directed by its star Seth Rogen, The Interview was described last year as a "blatant act of terrorism" by North Korea's state-run KCNA news agency.
Its scheduled release is thought to have motivated the orchestrated attack that saw films, confidential emails and Sony staff's salary details being leaked online.
Sony faced widespread criticism for initially cancelling the film's theatrical release, a decision that President Obama called a "mistake".
The US has placed sanctions on three North Korean organisations and 10 individuals after the FBI blamed Pyongyang for the cyber-attack.


Two men have been found guilty of shooting a man dead outside a prison in south London.

Darcy Austin-Bruce, 20, was visiting an inmate at Wandsworth Prison on 1 May 2009 when he was shot five times, the Old Bailey heard.
Rupert Ross and Leon de St Aubin, both from Fulham, west London, were found guilty of murder.
Ross, 30, disguised himself as a lawyer to gun down the victim while de St Aubin, 34, was the getaway driver.
The jury, which deliberated for 50 hours, was unable to reach a verdict on Khori Hines, 34, of Fulham, and on Casper Smith, 30, of Shepherds Bush. Both men denied the murder.
Ross, who came from a wealthy family and went to private Dulwich College, and de St Aubin, who was a fireman, will be sentenced on Thursday.
During the trial Crispin Aylett QC, prosecuting, said the smartly dressed gunman, who was wearing a crash helmet, and his accomplice escaped on a stolen moped after the attack.
The jury heard Ross, de St Aubin and Mr Austin-Bruce had been friends and were involved in drug dealing but they had fallen out.
Mr Aylett told the court: "To anyone who noticed him, the smartly dressed man must have looked like a lawyer making a legal visit to a client in the prison.
"There was, however, something slightly unusual about the man, in that he was wearing a crash helmet he had not removed from his head.
"This was, in the most literal sense, an inside job. The killers had been tipped off by someone inside the prison."


Retired appeal court judge Sir Patrick Coghlin will chair a public inquiry into the botched energy scheme that could cost taxpayers £490m.

Finance Minister Máirtín Ó Muilleoir said the judge would be "unflinching in his pursuit of the truth and scrupulous in his analysis of the evidence".
Sir Patrick will be supported by two panel members and, if needed, assessors from outside Northern Ireland.
He would begin gathering papers on 1 February, said Mr Ó Muilleoir.
"By getting to the truth of the RHI scandal, this inquiry team will... go some way to rebuilding the shattered public confidence in the institutions," he said.
The inquiry is expected to report its findings within six months.
The RHI scheme was intended to increase the creation of heat from renewable sources.
However, businesses have been receiving more in subsidies than they are paying for renewable fuel and the scheme became majorly oversubscribed.
The fallout from the scandal surrounding the scheme, which is approximately £490m over budget, resulted in the resignation of Sinn Fein's deputy first minister, Martin McGuinness, the collapse of Stormont's institutions and the calling of snap elections on 2 March.
Earlier on Tuesday, a judge issued an interim injunction preventing the publication of hundreds of names of RHI claimants.
The finance minister told the Assembly the areas the inquiry will investigate will be wide-ranging, including:
Mr  Ó Muilleoir said the inquiry would have the power to compel witnesses and evidence.
He also said that the inquiry would be in public and hopefully televised, but that Sir Patrick had decided there would be no public hearings before the election.
"Rest assured every stone will be turned and there will be no dark corners where the light won't shine, " he added.
He said Sir Patrick would have absolute control over the scope and execution of the Inquiry, which would be entirely independent.
No decision has yet been made on the venue for the inquiry, and no details were given on its anticipated cost.


Captain Alastair Cook said England would "work hard" on practising their catching after drawing the second Test match against South Africa.

Media playback is not supported on this device
Cook's men made 629-6 declared in their first innings, but then dropped eight chances in Cape Town and had to bat out the final day to make the game safe.
"If we'd taken those chances in the field I think we'd be talking about a different game," said Cook.
"Some were very difficult, maybe 10%. Others, we'd expect to take."
The draw means Cook's team retained a 1-0 series lead with two matches remaining.
He said: "You can't put down seven or eight chances, so we'll work hard in training after a couple of days off.
"These things happen. No-one plays a perfect game and no-one expects to drop a catch."
The dropped chances contributed to an uncomfortable final day for England.
With South Africa able to declare on 627-7 late on day four, the tourists were required survive the final day in order to avoid an unlikely defeat.
They slipped to 116-6 midway through the afternoon session, but were taken to safety by Jonny Bairstow and Moeen Ali.
"It's amazing," said Cook. "That's why everyone loves Test cricket.
"Full credit to South Africa for the way they batted under pressure, but we can also take a lot from this game.
"We were the team pushing for most of the game, putting South Africa under pressure."
England were propelled to their huge first-innings total by Ben Stokes' 198-ball 258, the second-fastest double century in Test history.
"It was a pleasure to watch, one of those you don't ever want to end," said Cook. "It was frighteningly good. Not many in the world have the ability to do that, so it's great that he's in our side.
"I don't think it's a one-off. I'm not saying it will happen every time he goes out to bat, but he will play innings that win matches for England."


Wigan maintained their 100% start to the season with a comfortable victory at north west rivals Oldham.

The visitors made it four straight wins in league and cup, but struggling Oldham have now suffered four consecutive defeats.
Wigan needed only eight minutes to go ahead as a short corner routine ended with Lee Evans crossing to Ivan Toney, who deflected home from six yards to register his first goal for the club.
The lead was doubled in the 16th minute, with Oldham's defence in disarray and Michael Jacobs seizing the chance to fire in a close-range drive.
It could have been 3-0 before half-time, but Nick Powell and Gavin Massey were both denied by home goalkeeper Ben Wilson.
Oldham had their best opening straight after the break when an Ollie Banks back-heel was smothered by Wigan goalkeeper Christian Walton.
Substitute Alex Gilbey wasted a chance to inflict more misery on the hosts, screwing off target from the edge of the box.
Ryan McLaughlin forced a save from Walton, but it was a largely untroubled afternoon for promotion favourites Wigan.

A Danish student has been convicted of killing a minibus driver in a head-on crash which also injured 10 passengers.

Stefan Hansen, 24, was found guilty of causing the death of 62-year-old Andrew Rennie by careless driving in the crash on the A83, Argyll, on 17 October 2013.
Hansen's Mitsubishi 4x4 collided with the minibus driven by Mr Rennie at Kennacraig, near Tarbert.
Sentence on Hansen was deferred and his bail was continued on the condition that he surrender his passport.
At the High Court in Edinburgh, judge Lady Stacey, told Hansen: "You appreciate you have been convicted of causing death and injury by careless driving."
The judge said she would allow him bail but added: "I am not prepared to allow you to return to Denmark."
Hansen had originally been charged with causing death by dangerous driving but was convicted of the lesser charge to which he had previously offered to plead guilty.
The court heard that Hansen had gone hunting on the day of the crash and had set off alone with a rifle.
He said he had turned onto the A83, taking the left hand side, but had crossed over on to the wrong side of the road after deciding to change the channel on the car radio.
Hansen told the court: "I just saw these two lights coming towards me and that's it. There is no time at all to react, just maybe hitting the brakes and try to avoid it," he said.
One of the passengers in the minibus, joiner Charles McCormick, said he had seen headlights coming towards them.
He said within seconds there was an impact and the windscreen shattered. "It was just mayhem after that," he added.
One police officer who attended the scene said she had spoken to the Danish driver who told her he had "got onto the wrong side of the road".
Another witness who made a call to the emergency services said the driver had said he had forgot what he was doing and drove up the wrong side of the road.
Mr Rennie was trapped in the minibus and collapsed after he was eventually freed. He died after suffering leg, chest and abdomen injuries in the crash.


With a little more than 1,000 days to go until the 2020 Tokyo Olympics begin, preparation - even at this stage - is key.

Such is the case with American swimmer Dana Vollmer, who claimed her seventh Olympic medal in Rio last year.
But she has had to adapt her preparation for Tokyo to cater for, in her words, the "bowling ball" in her stomach.
In her first race since Rio on Thursday, Vollmer was six months pregnant.
The first obstacle was finding a swimming costume that worked for her - up from the size 26 she wore in Rio to a size 32 at Thursday's race in Mesa, Arizona.
"It kind of holds everything in," she said, in an interview on the Team USA website. "We had to go up a few sizes to hold the belly."
Vollmer raced with her doctor's permission, and has amended her training programme while pregnant by doing more strength training.
In an interview before the race with ESPN, she said training was a welcome distraction.
"As hard as people think this is, the race is only 30 seconds long as opposed to the entire day I spend holding and chasing around a 35-pound two-year-old," she said. "This will feel like a break."
After winning gold in the 100m butterfly in the 2012 London Olympics, Vollmer took time off to have her first child, son Arlen, and returned in time to qualify for Rio.
But this time around, she has made the decision to continue training. Baby number two, a boy, is due in July.
"Putting the health of the baby first doesn't just mean sitting on the couch," the 29-year-old said.
Why it's OK to run when you are pregnant
Vollmer isn't the first woman to race while heavily pregnant - in June 2014, Alysia Montano competed in the 800m quarter finals of the US track and field championships while eight months pregnant.
Plenty of women have also taken part in the Olympics while pregnant, though none did in Rio, due to concerns over the effect of the Zika virus on unborn children.
The website of the US Swimming Masters, an organisation helping promote the sport, advises that women can carry on swimming even while heavily pregnant, but that each case is different.
Competing in the 50 metres freestyle only three months before giving birth did present one particular challenge for Vollmer.
"I don't think I've ever done a 50 where I took four or five breaths," she said. "A 50 felt long for the first time in my life."
In the end, Vollmer finished 55th in the preliminary round in Mesa, with a time of 27.59 seconds (last year, she swam the same race in 25 seconds).
Not that her time was a problem.
"Time didn't matter, place didn't matter," she said. "I've loved being here. I've loved seeing all my teammates, all the people from Rio. The race felt great."


Two men have been jailed after they stole 38 mobile phones from fans at a Libertines concert and stuffed them down one of their trouser legs.

Emanuel Paraschiv and Marius Buzura, both 30, from London targeted the audience at the Barclaycard Arena in Birmingham on 27 January.
Birmingham Crown Court heard Paraschiv, of Clarissa Street, Ilford, and Buzura, of Longbridge Road, Barking, admit conspiracy to steal on Friday.
They were each jailed for three years.

Police said there had been reports concert-goers were targeted at the band's performances in Manchester on 23 January.
Anyone who thinks they may have had their phone taken should contact police.


Prince William and the Duchess of Cambridge's visit to a Canadian charity that supports pregnant women struggling with addiction will be a "wonderful closing of the loop" of the work Princess Diana did in that same realm some 25 years ago, says the organisation's manager.

On Sunday, the royal couple will visit Sheway, which has helped vulnerable mothers since 1993 in Vancouver's Downtown Eastside, an area of the city that has become synonymous with urban poverty and substance abuse.
The visit is part of the upcoming Canadian tour by Will and Kate, and one of their first engagements over the week-long visit.
Manager Patti Zettel, who described the duke and duchess's planned visit as "mind-blowing," noted Sheway was modelled on a facility in Glasgow, Scotland, that had received Princess Diana's support.
"It shows a commitment to a particular group of marginalised individuals - women and addiction - for a quarter of a century now by the royal family," she said.
Princess Diana, Prince William's mother, embraced a wide range of humanitarian causes before her death in 1997. She advocated for the homeless and vulnerable youth, and took a personal interest in some unpopular causes of the time, including people with HIV/Aids.
The Sheway stop itself is brief - it's expected to last about an hour - but is important to the programme's clients.
"It's a validation that their lives and their experiences have meaning and that their stories deserve to be told," Zettel said.
Besides the visit to Sheway, over the course of some 30 separate engagements the duke and duchess will pay tribute to veterans of the Afghanistan conflict, will visit staff and volunteers who helped support Syrian refugees recently welcomed to Canada, will meet first responders, will travel to the Great Bear Rainforest - the world's largest temperate rainforest - and will meet a number of First Nations communities.
While the tour itinerary nods to Princess Diana's legacy and doesn't shy away from social issues, it also offers many opportunities to showcase the breathtaking natural beauty of British Columbia - Canada's western-most province - and the Yukon, a territory in the country's north.
Nathan Tidridge, who has written extensively on the monarchy, said Canadians rarely spend time thinking about the royal family despite the fact that Queen Elizabeth is the Canadian monarch.
Still, Tidridge said Canadians will tune in due to the "glossy magazine" aspect of the youthful royal family. By highlighting efforts towards reconciliation with Canada's First Nations, conservation and charity work, these tours help "tell our national story".
"Any moments that gather us together as a community are really, really, important. It's those intangible moments that royal tours really offer us," he said.
This is Will and Kate's second visit to Canada as a couple. They were previously in Canada in 2011, shortly after their wedding.
The Duke and Duchess will travel with their two young children, Prince George and Princess Charlotte.
As during the 2011 visit, the family is expected to be a popular draw.
Shachi Kurl, executive director of the polling group Angus Reid Institute, said coverage of royal tours in Canada tends to be positive, and Canadian opinion on the royal family tends to be personality driven - many like and respect the Queen and her grandson Prince William, though have lukewarm feelings towards the Prince of Wales.
But they are divided over the role of the monarchy in this country.
"When you remove the personalities from the equation and ask the bigger question about who should be our head of state, should we continue as the monarchy, or is that an outdated notion - there you do see some pretty big division in this country," she said.
Carolyn Harris, an historian and author, said that Will and Kate, as young, modern and relatable royals, have sparked a renewed interest in the royal family among Canadians.
"There is a sense now of there being a very clear future for the royal family [in Canada]."
24 Sept Victoria,  British Columbia: Their Royal Highnesses, accompanied by their children Prince George and Princess Charlotte, arrive in Victoria, the capital of British Columbia.
25 Sept Vancouver, British Columbia:  The Duke and Duchess will visit Sheway, the Immigration Services Society of British Columbia, an event celebrating young leaders in Canadian arts, music, sport, charity, business, and film, and finally the visit the Kitsilano Coastguard Station.
26 Sept Bella Bella and the Great Bear Rainforest, British Columbia: The Duke and Duchess will travel to the Great Bear Rainforest, visit with  the Heiltsuk First Nations community and attend a reception hosted by the province of British Columbia at Government House.
27 Sept Kelowna, British Columbia and Whitehorse, Yukon: They will tour the Okanagan campus of the University of British Columbia and take part in the BC Government's "Taste of British Columbia" festival at Mission Hill Winery before flying to Whitehorse, where they will be greeted by members of the Canadian Rangers.
28 Sept Whitehorse and Carcross, Yukon: Will and Kate will visit the MacBride Museum and meet members of Whitehorse's cultural community before travelling to Carcross, where they will be welcomed by the Carcross/Tagish First Nation.
29 Sept Victoria, British Columbia: The royal couple and their children attend children's party in the grounds of Government House, which will be attended by military families.
30 Sept Haida Gwaii, British Columbia:  The Duke and Duchess visit Haida Gwaii, the archipelago on the northern coast of British Columbia and is home to the Haida Nation. They will attend the opening of the new Haida Gwaii Hospital and Care Centre. They will join local youth for a fishing expedition on the waters of Hecate Strait.
30 Sept Victoria, British Columbia: The royal couple will visit the Cridge Centre for the Family, which provides services and support for women who have experienced domestic violence. They will then meet families who have received support from the Kelty Mental Health Resource Centre and later youth working with the Sail and Life Training Society. They end their tour with a public official departure ceremony at Victoria Harbour Airport.


The chairman of South Africa's power utility has resigned following calls for him to be sacked over allegations of interfering with operations.

Eskom made the announcement after deliberating with Zola Tsotsi on a motion of no-confidence.
Mr Tsotsi recently made headlines when he suspended four senior executives over ongoing problems at the company.
South Africa has been plagued by power outages in recent months, leading to widespread criticism of Eskom.
An inquiry is underway at Eskom into the reasons behind poor generation capacity and cash-flow issues.
A decision on the suspended bosses will only be taken once the investigation has been completed, the power utility has said.
Economists warn that if the energy problems are not resolved in Africa's most developed economy, it could further stunt the country's growth prospects.


Assistant coach Rob Howley says Wales are in New Zealand to make history as they aim to beat the world champions in their own country for the first time and end a 63-year winless streak.

Wales have lost 26 consecutive matches against the All Blacks, with their last win coming in 1953.
Warren Gatland's side play three Tests against New Zealand this month.
"We are here to try and change history and what's gone before us, that's our goal," said Howley.
New Zealand are unbeaten at Eden Park since 1994 and the match in Auckland will be the All Blacks' first since beating Australia 34-17 in the World Cup final.
The hosts are heavy favourites to win the Test series, but Howley says Wales must not let that concern them.
"There is something of a siege mentality which can benefit teams when you come over to the southern hemisphere," said Howley.
"History is against us, but we need to change history and by trying to create a siege mentality that might put us, hopefully at some time on Saturday, in a good space and putting the All Blacks under pressure on some occasions."
Wales were widely regarded as Europe's strongest team at the 2015 World Cup where they reached the quarter-finals.
But they finished second behind a rejuvenated England in the 2016 Six Nations, and came in for criticism at home for the style of their play during that championship.
Howley says Wales are evolving their game and looking to add some variety to their play before meeting the All Blacks, a team the former scrum-half described as "relentless" in everything they do on the field.
"Skill set under pressure is vital in the modern game and we are continually working on it," he said. "It's about speed and mindset. It takes time, but it's something which we are very mindful of.
"Hopefully you will see not just glimpses of it on the weekend, but quite a lot of it."


Andrew Hore is to leave his role as Ospreys chief executive to take over at Australian Super Rugby side Waratahs in April.

Former Ospreys prop Andrew Millward will become their managing director.
Hore, 43, a former Welsh Rugby Union and New Zealand Rugby high performance manager, has been chief executive of the Pro12 outfit since 2013.
He previously confirmed the Waratahs' interest in him on the day Ospreys announced a first profit since 2007.
Hore, who became Ospreys elite performance boss in 2008, has also been named as the new chief executive of the New South Wales Rugby Union (NSWRU) in Australia.
Waratahs' chief executive Greg Harris has left after a restructure involving them and the NSWRU.
"As a seasoned administrator, with experience in international rugby circles, Andrew brings to the joint CEO role a unique set of competency skills that distinguished him from the other quality candidates in the global search," said Waratahs chairman Roger Davis.
Hore came to Wales as conditioning coach under then-national coach Steve Hansen in 2002, left in 2005 to join New Zealand Rugby Union as high performance manager and three years later arrived at Ospreys.
He went on to hold the title of chief operations officer at Ospreys in 2010 and chief executive in 2013.
Ospreys chairman Roger Blyth said: "Andrew brought energy, drive and knowledge to the Ospreys during his time here and I'm sure Andrew would agree he has also learnt considerably from our environment, allowing him to develop as a manager."
Hore says his decision to leave was "difficult" and comes after an "incredibly difficult period for both the Ospreys and the wider game in Wales".
He added: "We've come through that period thanks to a huge collective effort from so many people and, I believe, Ospreys Rugby as a business is in a far better position than could have been hoped just a few years ago.
"I genuinely believe that the Ospreys don't get full credit within Wales for what they have achieved over the years, be that commercially with the business now a profitable and sustainable one, or, continuously, in rugby terms, where they lead the way by any measurement possible.
"I hope that will change in the years to come, particularly in what is a rapidly evolving rugby, media and business landscape in Wales."
Ospreys chairman Roger Blyth said: "Everyone at the Ospreys will be well aware of the impact Andrew has had across all areas of the business during his time here, and will be forever grateful for all his efforts to improve our organisation."
Millward moves up from the role of rugby general manager, having previously been regional performance manager.
"It's an exciting opportunity for me and I'm looking forward to continuing to play a part in ensuring we stay at the forefront of European rugby, on and off the field," Millward told the Welsh region's website.
Former Swansea and Wales full-back Blyth said: "Andrew (Millward) will take on most of the current CEO's duties while, where necessary, we will look at other areas within the business to fully cover the role. "
Blyth added: "With Andrew (Millward) stepping up to the new role, it provides an opportunity for us to enhance the senior rugby management team and strengthen our day-to-day operations at Llandarcy and that is something we are presently looking at."


Police in the Highlands have issued an appeal asking people to help find a little girl's cherished teddy.

The bear was lost in Dingwall, according to a tweet from the force.
Officers based in Ross and Cromarty asked if people in the town could keep a look out for the youngster's favourite bear.
The missing bear is brown and fluffy.


A spoof news website has been recognised as an "official media outlet" by a council after it gained thousands of followers on social media.

Southend News Network's stories include a mother demanding a Â£50 spend on gifts for her son's birthday and a restaurant introducing a Â£5 breastfeeding charge.
Its creator said he "never thought" his site would be officially recognised.
Southend Council said it was better to "have fun" with the spoof stories rather than get annoyed by them.
Other fake stories published on the site since its launch last October include school pupils being taught by cats because of a teacher shortage and the Dartford Crossing being closed because of "thousands of Kent residents trying to enter Essex illegally".
The local authority said it had received calls from concerned residents about some of the stories, including one about trick or treaters needing a council permit at Halloween.
Following a meeting with council officials, the spoof news site has been added to the authority's media database and is treated similarly to more traditional local newspapers and broadcasters.
The site's anonymous creator, who prefers to be known by the nom de plume "The Chief Reporter", said he had been inspired by satirical news sites such as The Onion, The Daily Mash and The Poke.
"My stories are tapping into the types of things people get wound up about. I like a heated, healthy debate," he said.
"Some of the things I write, I could actually see happening in real life. It's how people feel about their own town, their own lives - it taps into that and builds on it."
The reporter said Southend Council had "recognised we're building up town's public profile" with the site, which has more than 6,000 Facebook likes.
Adam Keating, a media manager at the local authority, said interacting with Southend News Network allowed the council to build on its own social media profile.
"Although their stories might not be correct, they've built up a following we could also engage with," he said.
"People have been commenting on the posts with real issues, and we've been replying with facts about 'the truth behind the spoof'.
"The media landscape is changing, and we're treating Southend News Network in the same way we would other local news sites or community groups."


New artwork inspired by large rocks that roll around the seabed of the Pentland Firth have been installed at John O'Groats.

Dundee-based artists Matthew Dalziel and Louise Scullion have created the art called Nomadic Boulders.
They were commissioned as part of a project involving Highlands and Islands Enterprise to revamp John O'Groats.
HIE said the art had to be designed to withstand the forces of 100mph winds that sometimes blow through the area.
Stones believed to be 25cm to up to 100cm in diameter are moved by fierce tides in the Pentland Firth.
Nomadic Boulders uses boulders which appeared on a neighbouring beach after a storm.


Parts of the Digital Economy Act that deal with illegal file-sharing are being challenged in the High Court.

Internet providers BT and TalkTalk demanded the judicial review, arguing that the legislation was rushed through parliament without proper debate.
They claim that the measures unnecessarily impact users' privacy and force ISPs to police copyright infringement on the net.
If the court finds in their favour, the act would no longer be enforceable.
"It is a big deal to be judicially reviewing primary legislation but we took advice and there were very clearly were some real problems," said Simon Milner, BT's head of industry policy.
"It might find that it is all fine - I'd be surprised if  it was - but we are going to court to get legal clarity," he added.
The courts will consider whether the act is in line with European legislation, in particular as it relates to users' privacy and the role of ISPs.
The previous government brought in the tough measures to deal with the growing issue of internet piracy.
Under the current legislation, content providers will have to monitor peer-to-peer networks for illegal activity and collate the IP addresses - the numerical code that links a particular computer network to an illegally downloaded file.
They can then apply to a court to force ISPs to surrender the real world address that is connected to that IP address.
Letters could then be sent to alleged net pirates, advising them that their computer connection has been used in illegal activity.
The creative industry is keen that the emphasis will be on education initially, although people will go on a blacklist which could in future be used to take individual infringers to court.
Other penalties, such as slowing down net connections or even cutting people off from the net entirely have not been ruled out, but would need additional legislation.
The letter-writing strategy bears similarities to the tactics of discredited law firm ACS: Law, which sent over 10,000 letters to alleged net pirates.
Unlike content providers, which will not be levying fines, ACS: Law collected some £300,000 from people - who were charged an average of £500 per infringement.
Not everyone paid up and 27 cases recently went to court in highly controversial circumstances.
Lead solicitor Andrew Crossley attempted to discontinue the cases shortly before the hearing was due and was accused of obstructing the court process.
In the middle of the case, Mr Crossley said he no longer wanted to be in the business of chasing net pirates and the cases were eventually thrown out.
But he faces an investigation for his conduct from the Solicitors' Regulation Authority and could be hit with legal costs for the cases he brought.
During the court case, doubt was cast over whether an IP address was suitable evidence of wrong-doing as it does not identify the individual user - only the location of their connection.
Consumer watchdog Which? highlighted several cases where people claimed to have been wrongly accused.
Charles Dunstone, chairman of TalkTalk, thinks the same thing will happen if the government's measures go ahead.
"Innocent broadband customers will suffer and citizens will have their privacy invaded," he said.
Jim Killock, director of the Open Rights Group, said that he is particularly worried about how the legislation will affect public wi-fi hotspots.
"We need to start again and find a new policy settlement which embraces, rather than tramples on, the exciting possibilities that the digital age offers," he said.
John McVay, chief executive of PACT (Producers Alliance for Cinema and TV), who will represent the UK's creative industries at the judicial review, defended the act.
"The Digital Economy Act is the result of many years of consultation and presents a reasonable and balanced solution," he said.
But Mark Mulligan, an analyst with Forrester Research, warned that even if the act remains intact, the measures won't work because they are already out-of-date.
"Peer-to-peer file-sharing is yesterday's game. People now are going off the network where they won't be detected - swapping hard-drives, and getting music via blogs and upload sites," he said.


One subtle, but important difference in the House of Lords is where the hundred Lib Dem peers will now sit on the Opposition sideâ€¦

They've not gone back to their former seats in pre-coaltion days. Instead, they've shifted position slightly, to occupy a strategic space between the Labour peers and the crossbenchers. It's a convenient spot from which to coordinate anti-Government majorities in the Upper House, and exert what little political leverage remains for the Lib Dems in Westminster.
The arithmetic in the Lords certainly suggests that the government will face a hostile majority of peers, quite a lot of the time. But the reality is that that majority will be constrained by the ingrained conventions of the Upper House.
Chief among these is the Salisbury-Addison Convention, the deal struck in 1945, between "Bobbity" Salisbury, the leader of the Conservative peers, (and part of a political dynasty which stretches back to Elizabeth I's Privy Council), and Lord Addison, the old Asquithian minister who then led a tiny band of Labour peers.
Deal struck
At that time the Conservatives utterly dominated the Lords, but a Labour government had been elected by a landslide - so a deal was struck that the Lords would not strike down at second or third reading, any legislation which had appeared in the winning party's manifesto, and could therefore be assumed to have the approval of the electorate.
It was a development of earlier doctrines, dating back to the Duke of Wellington, and then extended during Gladstone's struggle to disestablish the Church of Ireland. The idea was to reconcile the power of the Lords with the increasing importance of the popular vote.
The 1945 deal effectively surrendered the right, regularly exercised 40 years before, against the Liberal governments of Campbell Bannerman and Asquith, to pole-axe any bill peers didn't fancy, at the first opportunity. But, crucially, it still left scope for bills to be amended, even gutted, later in the legislative process - particularly at report stage consideration.
So, even bills foreshadowed in the Conservative manifesto will not be immune from the attentions of Their Lordships, although in practice, the government will have to lose the argument on the floor of the House, and lose pretty badly, for a bill to be totally undermined. So how might this apply in the coming year?
The first point to make is that the opposition parties in the Lords won't take a swing at every government measure. All the major groups will pick their battles carefully, and they might not always pick the same ones; Labour might support some of the package of internet surveillance measures (AKA the "snoopers charter") that the home secretary is pledged to bring in.
The Lib Dems undoubtedly will oppose it - and may rather relish doing so alone.
Pinch points
The most obvious case for treatment will be the promised bill to create a British Bill of Rights and end the jurisdiction of the European Court of Human Rights. That central aim is opposed by Labour, the Lib Dems and many of the legions of lawyers on the crossbenches - not to mention by a number of Conservative peers, and that's before they get onto the implications for the devolution settlements in Scotland and, especially, Northern Ireland, where the ECHR is embedded in the Good Friday Agreement.
What else? The list of government defeats during the last Parliament provides a handy checklist of possible action points for the new set of ministers - on judges' discretion over costs in judicial reviews (Criminal Justice and Courts Act); on legal aid for disabled people (SI under the Legal Aid etc Act); a whole raft of issues in the Enterprise and Regulatory Reform Act on things like civil liability in health and safety cases; on quangos that were saved from abolition under the Public Bodies Act and any number of benefits changes under the Welfare Reform Act.
With the other main parties in some disarray, ministers may seek to reverse some of those defeats and unpick some of the compromises they were forced into, during the last Parliament. Sometimes this will involve new bills, sometimes it may mean votes on statutory instruments - but I'm told the opposition parties are on the alert.
In the last Parliament, Labour peers fought a bitter delaying action against the Parliamentary Voting and Constituencies Bill; the Lib Dem peers certainly plan to make life difficult for the government, but intend to do so "within the spirit and conventions of the House", according to one senior figure.
So expect late votes to be forced on random amendments, and expect the government to find itself forced to negotiate the content of its bills rather more often than it would like.


Classic 1990s game show The Crystal Maze is set to return for a one-off charity special.

Channel 4 confirmed to BBC News it was "looking at options" for the show, which would form part of its Stand Up To Cancer fundraiser in October.
According to reports, the problem-solving show would feature celebrity contestants, with former Doctor Who star David Tennant tipped to host.
However Channel 4 said it was "premature" to confirm the details.
The Crystal Maze originally ran from 1990-95 and was first hosted by Rocky Horror Show creator Richard O'Brien and then Ed Tudor-Pole in its last two years.
It saw members of the public tackle a range of physical, mental, skill and mystery timed challenges across four themed zones.
The format was recently revived as an immersive live experience in London thanks to a crowdfunded project.
Organisers for the The Crystal Maze experience told Buzzfeed the new Channel 4 special would be filmed on their premises.

Great Britain's men began their Champions Trophy campaign with an encouraging 0-0 draw against world number one side Australia.

Media playback is not supported on this device
Hosts GB are aiming to win the event for the first time and were indebted to goalkeeper George Pinner who made a series of saves to keep the game level.
Mark Glenghorne came closest to a winner for GB, but was denied by Simon Orchard in the Australia goal.
"As a team we pride ourselves on our defence," Pinner told BBC Sport.
"It really was a great performance with everyone throwing themselves in there, putting their bodies on the line and that's what you need to win tournaments."
The Champions Trophy in London sees six of the best teams in the world compete in the final major international tournament before this summer's Rio Olympic Games.
All six nations will face one another in the pool stage, with the top two ranked teams facing off for gold on the final day - those ranked third and fourth will compete for bronze.
Earlier on Friday, South Korea took an early advantage with a 2-0 defeat of Belgium, while defending champions Germany needed a late equaliser to salvage a 3-3 draw against India.
The GB men will face 2014 Champions Trophy runners-up India in their second fixture at 16:00 BST on Saturday and will be hoping for goal-scoring improvements.
They relied not only on Pinner but also two crucial video referrals, which overturned a penalty stroke and a goal, having both initially been awarded to Australia.
"We take encouragement from the result and we know the performance can get better," captain Barry Middleton told BBC Sport.
"Tournament hockey isn't always about who plays their best at the beginning, it's about if you can build through the tournament and finish strong and that's what we're looking to do."


Defender John O'Shea has signed a new one-year contract with Sunderland.

The 36-year-old club captain made 30 appearances on Wearside last season but was out of contract this summer.
New boss Simon Grayson has confirmed the Republic of Ireland defender has extended his stay at the club, for whom he has played since 2011.
O'Shea, capped 116 times by his country, is Sunderland's all-time leading appearance-maker in the Premier League.


Linkin Park singer Chester Bennington's funeral has taken place just over a week after his death at the age of 41.

The private service was held near his home in Palos Verdes, California, according to TMZ.
Guests were given wristbands and access passes similar to VIP concert passes, featuring an image of the star.
Bennington's body was found at a private home in Los Angeles on 20 July. A coroner said the star apparently hanged himself.
A stage with a drum kit was set up at the funeral.
About 200 family members, friends and musicians attended the service. They included hip-hop star Blackbear, who wrote on Twitter:

Linkin Park records flooded the UK charts last week following the frontman's death.
Their debut album Hybrid Theory was their highest-placing album at number four. It includes hit song In the End, which was the highest-charting Linkin Park entry on this week's singles chart at number 14.
The band have now become the first US band in 50 years to secure three albums in the top 10.
Linkin Park paid tribute to Bennington in a statement last week.
"Our hearts are broken. The shock waves of grief and denial are still sweeping through our family as we come to grips with what has happened," it read.
"You touched so many lives, maybe even more than you realised."
Formed in 1996, Linkin Park have sold more than 70 million albums worldwide and won two Grammy Awards.
The band had a string of hits including Faint, In The End and Crawling, and collaborated with the rapper Jay-Z.

Consultants will put concerns about staffing shortages and patient safety at Aberdeen Royal Infirmary directly to the Scottish government.

They held a meeting in the city on Tuesday night to discuss a number of issues, particularly relating to the situation in the emergency department.
The health board last week board announced a Â£2m investment in ARI frontline services.
NHS Grampian previously said it had been facing "staffing challenges".


Roedd AC Plaid Cymru, Neil McEvoy - sydd wedi ei wahardd dros dro am fwlio - yn ymwybodol bod bargyfreithiwr yr oedd yn ei ddefnyddio wedi ei gael yn euog o fwlio ac aflonyddu cydweithwraig.

Daeth Panel Arfarnu Cymru i'r casgliad bod Mr McEvoy, sydd hefyd yn gynghorydd, wedi torri cod ymddygiad Cyngor Caerdydd ond heb ddwyn anfri ar yr awdurdod.
Cafodd cwnsler Mr McEvoy, Jonathan Gwyn Mendus Edwards, ei wahardd am bedwar mis yn 2013 am aflonyddu clerc yn rhywiol yn ei siambr a/neu gwneud sylwadau sydd gyfystyr â bwlio.
Yn y gorffennol mae'r AC wedi dweud ei fod yn "tynnu sylw at unrhyw gamdriniaeth dwi'n ei weld, waeth faint o drafferth mae'n ei achosi i fi".
Dydd Mercher, dywedodd Mr McEvoy wrth BBC Cymru: "Ar delerau pro-bono mae Jonathan wedi gweithio, sy'n golygu nad ydw i wedi ei gyflogi.
"Mater i Mr Edwards ei hun yw ei orffennol, a does gan hynny ddim effaith ar fy achos i. Mae'n fargyfreithiwr cyfreithlon sydd â'r hawl i weithio."
Fe ddywedodd Mr Mendus Edwards bod yr AC wedi cael gwybod am yr hanes ychydig cyn ei wrandawiad yn y tribiwnlys.
Gan gyfeirio at ei achos disgyblu ei hun, dywedodd: "Roedd 'na gamweinyddu cyfiawnder yn y ffeithau, gan bod fy margyfreithiwr fy hun heb ddod i'm achos.
"Cafodd ei ddisgyblu am achosi rhagfarn yn fy erbyn. Dylai neb orfod cynrhychioli eu hunain, ac fe orfodon nhw i mi wneud hynny.
"Mae'n anodd cwffio achosion yn sgil y diwylliant o amgylch cwynion. Dwi'n cefnogi fy nhair merch ym mhopeth maen nhw'n ei wneud. Ac mae fy ngwraig yn fy nghefnogi i."
Roedd Mr Mendus Edwards yn ymgeisydd dros Blaid Cymru yng Ngŵyr yn etholiad cyffredinol 1983. Doedd Plaid Cymru ddim am wneud sylw.


A 31-year-old man has been charged with distributing a terrorist publication, Scotland Yard has said.

Mohammed Alam, of Croydon, south London, was arrested at a business address on Tuesday by officers from Counter Terrorism Command.
Armed officers were present but no shots were fired.
He appeared at Westminster Magistrates' Court on Thursday, where he was remanded in custody to appear at the Old Bailey on 8 January.
He was charged under the Terrorism Act 2006 with distributing or circulating a terrorist publication.


Braintree Town are performing a "football miracle" by being two points off the National League play-offs, according to Iron boss Danny Cowley.

The Iron's 2-0 loss to lowly Boreham Wood left them seventh, but with a game in hand over fifth-placed Dover.
"You have to remember we're Braintree Town. Look at the clubs around us, the infrastructure, the size, the fact that they're full-time," he said.
"I see what the boys have done thus far as being a football miracle."
Tuesday's loss to the Wood came after a run of three wins from four for a side that also took League Two promotion hopefuls Oxford to an FA Cup first-round replay this season.
Cowley, who took charge in the summer, has previously criticised the scheduling of National League matches.
He continued to BBC Essex: "We've got ourselves in a great position and given ourselves a foundation and we'll work very hard and see where it takes us.
"But I don't see the play-offs as being a reality, not for this football club. That's not to say we won't be trying very hard to be in and around it, but I always think there has to be a touch of realism."


Several former police officers have beaten party candidates in the first-ever elections for crime commissioners in England and Wales.

So far, Labour and the Conservatives have roughly split most contests, but independents won 11 of the 41 posts.
Voter turnout was historically low, leading the Electoral Commission to describe it as "a concern for everyone who cares about democracy".
With all ballots counted, turnout was about 14.9%, BBC research showed.
Prime Minister David Cameron said low turnout in a first-time election was expected.
"It takes time to explain a new post," the prime minister said, and he predicted voting numbers would be "much higher next time round".
The Conservatives have won 16, Labour 13 and independents 11, with one other successful candidate.
One of the most high-profile defeats was in Humberside where Labour former deputy prime minister Lord Prescott lost to Tory rival Matthew Grove.
Police and crime commissioners will have powers to hire and fire chief constables and set police strategy and budgets.
The government says PCCs will give local people more control over policing, but opponents have warned the changes will politicise the police - and low turnout shows people don't want them.
In other election developments on Friday:
The record low for a national poll in peacetime is the 23% turnout for the 1999 European elections.
Turnout in the PCC election was 12.9% in Merseyside, 13.3% in Thames Valley, and 13.5% in Greater Manchester. These figures include spoilt ballot papers.
Electoral Commission chairwoman Jenny Watson said: "These were new elections taking place at an unfamiliar time of year, which is why we have made clear at every stage that it would be important to engage effectively with voters.
"The government took a number of decisions about how to run these elections that we did not agree with. But what is important now is that the right lessons are learnt: we will talk to voters, candidates and returning officers to understand what worked and what didn't.
"The commission is going to undertake a thorough review, and we will present our findings to Parliament in early 2013."
Elections expert Professor John Curtice, of Strathclyde University, said it could be the worst turnout ever.
He added the elections "raised questions" about whether the whole exercise was worth it.
Deputy Prime Minister Nick Clegg said a general apathy towards politics was to blame for the low turnout.
He said: "We are at a mid-term point in this government, there's a lot of difficult news around at the moment."
But Downing Street sources partly blamed the media, saying because the elections had not been held in London they had generated insufficient national news coverage.
"The national media have not covered themselves in glory," a No 10 source said.

Home Secretary Theresa May  said first elections were always difficult. "The police and crime commissioners are visible, they'll be accessible, they've been elected and crucially they will  be accountable to people through the ballot box."
Shadow home secretary Yvette Cooper said many people had been cross about a lack of information, including what the job entailed and who the candidates were.
"It's not acceptable to be so careless with democracy, so careless with policing,  but also so careless with money for the tax payer too."
Labour's Chuka Umunna called the elections "a total shambles", suggesting the Â£100m cost would have paid for 3,000 police officers.
Turnout reached 27.48% in the PCC election in Bristol, where voters were also going to the polls to choose the city's first directly-elected mayor, but across the Avon and Somerset police area as a whole it dropped to 19.58%.
Darren Hughes of the Electoral Reform Society said the PCC elections had started as a flagship government policy, but had descended into a "farce".
He said having an election in November was "crazy", but resourcing of the election needed to be addressed as well, so that candidates are able to cover areas larger than a usual constituency.
One of successful independents in England, Ann Barnes, a former Kent Police Authority chairwoman, said the "real winners are the people of Kent who did not want their police force to be politicised".
In Dorset, successful candidate Mr Underhill said his "number one" priority was to hire a chief constable "with my vision".
"There's a lot to do in the first 100 days."
The first PCC for Lancashire, Labour's Clive Grunshaw, said it was a "new era for policing", while the North Yorkshire PCC, Conservative Julia Mulligan, said she intended to work hard "without political prejudice."
In Thames Valley, Anthony Stansfeld said after his election success: "I am a Conservative but I haven't had a gilded life. You grow up quickly commanding a platoon in the jungles of Borneo."


Four children are seeking £200,000 in damages from Swansea council, over claims it did not protect them from their abusive parents.

It is alleged that one child had seen its parents snort cocaine and another was still wearing nappies aged seven.
The children were eventually put into foster care but lawyers acting on their behalf say that should have happened sooner.
Swansea council said it would be "inappropriate to comment".
The legal action has been launched on the children's behalf by the Official Solicitor - part of the justice ministry which acts for those too vulnerable or young to sue for themselves.
Papers lodged with the Royal Courts of Justice in December 2016 also allege that the mother had refused to take one of her children to hospital despite it having breathing difficulties.
The mother and child were later escorted to hospital by police.
The action claims the local authority should have done more to protect the youngsters from "physical and emotional abuse and neglect which they were subject in their family home".
The papers state the claimants expect to recover more than £200,000, saying their parents had been known to social workers for "quite some time".


David Cameron ended some text messages to Rebekah Brooks with the letters LOL, she has told the Leveson Inquiry.

The former Sun and News of the World editor was asked about the frequency of text contacts between the two when she was head of News International.
She said the prime minister signed off most texts with the letters DC but occasionally used the acronym LOL.
But she said he stopped this when he learnt the text shorthand stood for "laugh out loud" not "lots of love".
The disclosure became an instant topic of discussion on micro-blogging site Twitter, with a number of Labour politicians signing off their tweets on the subject lol.
Mrs Brooks was questioned for more than five hours about her relationship with politicians including Mr Cameron and former prime ministers Tony Blair and Gordon Brown and decisions taken by her papers when she was editor.
Mrs Brooks also told the inquiry she had the express permission of ex-Prime Minister Gordon Brown and his wife Sarah to run a story in 2006 about their son Fraser being diagnosed with cystic fibrosis.
But the Browns have issued a statement
saying that "at no stage" was their permission sought.
She also told the inquiry into press ethics that suggestions Mr Cameron texted her up to 12 times a day while opposition leader were "preposterous" as both he and her had "better things to do".
The two exchanged messages about once a week although contacts increased to about two a week in the run-up to the 2010 general election.
Most messages, she said, were to discuss "organisation" or future social occasions but in one instance, she commented on Mr Cameron's performance in the first leadership debate, telling the opposition leader it was "not very good".
Mrs Brooks was pressed by the lead counsel for the inquiry, Robert Jay QC, on how Mr Cameron signed off his texts, saying "everyone wanted to know".
Asked by Lord Leveson why he had posed the question, Mr Jay said if he did not "people would inquire why the question was not asked".
In response, Mrs Brooks said the prime minister would use DC "in the main".
But she added: "Occasionally he would sign them off LOL, lots of love. Actually, until I told him it meant laugh out loud and then he did not sign them like that any more. But, in the main, DC, I would have thought."
After the brief exchange, Lord Leveson urged Mr Jay to "move on" to other subjects.
Conservative commentator Iain Dale has said Mrs Brooks was not alone in getting texts of this kind, saying he had also received messages signed LOL, DC.
"He does it to lots of people," said the blogger and radio presenter.
But former Lib Dem MP Evan Harris claimed that he had texted the prime minister after the birth of his daughter Florence in August 2010.
In a tweet
, Mr Harris, who is a spokesman for the Hacked Off campaign which is seeking justice for victims of phone hacking, wrote: "He replied. Without an "lol" or even an "x".
And former deputy prime minister Lord Prescott sent a
          Twitter message
 to Number 10 saying he would put in an Freedom of Information (FOI) request to see all texts between Mr Cameron and Mrs Brooks.
Lord Prescott signed off his tweet, "keep your head up. LOL!" - a reference to a message reportedly passed on to Mrs Brooks by No 10 after her resignation in 2011.
The BBC's political correspondent Ross Hawkins said Lord Leveson could ask for all Mrs Brooks' text messages - many of which are unavailable after her Blackberry was "frozen" after she left News International - to be given to the inquiry.


Psychologists from the University of Stirling are to play a central role in a £6m study to develop next generation face-recognition technology.

The five-year project will bring university research teams from across the UK together with the Home Office and industry specialists.
They will examine how face recognition can improve global security and commerce.
Scientists from Stirling will offer expertise on face perception.
Prof Peter Hancock, from the university's psychology department, will lead the Stirling team as they investigate how humans recognise familiar faces.
The professor previously helped to develop "EvoFIT" - a facial recognition system which is used by police forces around the world.
Prof Hancock said: "Humans are surprisingly poor at identifying faces they don't know, even professionals such as passport controllers have difficulty matching people to their photographs.
"But we are much better than machines at recognising familiar faces and the challenge we are undertaking is to gain an understanding of what the process is that allows us to do this."
The project will also look at the privacy implications of the technology.
Global security is the "prime driver" for the the study, but it is hoped there will be commercial benefits as well.
Prof Hancock added: "In the future it could be your bank will recognise you automatically at the cash machine and remove the need for pin numbers.
"The BBC are also interested in how it might make accessing their vast archive more efficient."
The project begins in January.


A man who died after being stabbed has been described as a loving son and brother with an "infectious smile".

Officers were called to an address in Bryn Heulog, Old Colwyn, Conwy county, at 20:30 GMT on Thursday and David Kingsbury, 35, was found dead nearby.
In a tribute, his family said they will miss his "easy going nature".
On Saturday, North Wales Police were granted a further 36 hours to question a 38-year-old woman arrested on suspicion of murder.
A post mortem examination revealed Mr Kingsbury died from a single stab wound.
In the tribute, his family said: "David was a very loving, affectionate son, brother and uncle with a good heart.
"We all loved him to bits and will miss his happy, easy going nature, his infectious smile and sense of humour."
Det Insp Arwyn Jones said officers want to speak to people who were in Aldi or the Co-op store on Abergele Road, Old Colwyn, between 20:30 and 21:00 on Thursday.


Forensic examination has begun of land in County Meath for an IRA victim whose body has been missing for almost 40 years.

It is believed Brendan Megraw's remains are buried somewhere at a bog in Oristown, County Meath.
He was one of the 16 murder victims that became known as the Disappeared.
Mr Megraw was 23 years old when he was abducted from Twinbrook in Belfast in 1978, and murdered by the IRA.
The IRA claimed that he had confessed to being a British provocateur and Military Reaction Force undercover agent.
There have been three unsuccessful searches for him, the most recent in 2010.
Last week, the Independent Commission for the Location of Victims' Remains (ICLVR) announced that a new search would get underway.
They said that a "geophysical survey" would be carried out on 2.5 hectares of land.
After the announcement, the brother of the victim, Kieran Megraw, said the family were wary of getting their hopes up.
"You're thankful that information has come in," he told BBC Radio Ulster's Good Morning Ulster.
"But you have to temper your expectation and hope. You're hoping then the results of the survey will say it's okay to go ahead."
Senior forensic investigator for the ICLVR, Geoff Knupfer, said no one, particularly the Megraw family, were "under any illusion" about the search.
"But, with the right information, we are confident we can find Brendan," he said.
It is thought the search involves a survey of the site by forensic archaeologists using radar to try to identify anomalies beneath the surface.
A decision will then be made on whether to start fresh excavations.
