The British Antarctic Survey (BAS) has released new footage of the ice crack that promises to produce a giant berg.

The 175km-long fissure runs through the Larsen C Ice Shelf on the eastern side of the Antarctic Peninsula.
If it propagates just 20km more, a block of ice a quarter the size of Wales will break away into the Weddell Sea.
Scientists gathered the new video while recovering instrumentation that had been placed on the ice shelf.
Uncertainty about the stability of the region means researchers cannot set up camp as they would normally do, and instead make short visits in a Twin Otter plane.
The most recent sortie enabled the researchers also to fly along the length of the crack, which is 400-500m wide in places, to assess its status.
No-one can say for sure when the iceberg will calve, but it could happen anytime.
At 5,000 sq km, it would be one of the biggest ever recorded.
When it splits, interest will centre on how the breakage will affect the remaining shelf structure.
The Larsen B Ice Shelf further to the north famously shattered following a similar large calving event in 2002.
The issue is important because floating ice shelves ordinarily act as a buttress to the glaciers flowing off the land behind them.
In the case of Larsen B, those glaciers subsequently sped up in the absence of the shelf. And it is the land ice - not the floating ice in a shelf - that adds to sea level rise.
If Larsen C were to go the same way it would continue a trend across the Antarctic Peninsula.
In recent decades, a dozen major ice shelves have disintegrated, significantly retreated or lost substantial volume - including Prince Gustav Channel, Larsen Inlet, Larsen A, Larsen B, Wordie, Muller, Jones Channel, and Wilkins.
Dr Paul Holland from BAS commented: "Iceberg calving is a normal part of the glacier life cycle, and there is every chance that Larsen C will remain stable and this ice will regrow.
"However, it is also possible that this iceberg calving will leave Larsen C in an unstable configuration.  If that happens, further iceberg calving could cause a retreat of Larsen C.
"We won't be able to tell whether Larsen C is unstable until the iceberg has calved and we are able to understand the behaviour of the remaining ice."
The removal of the ice would also enable scientists to study the uncovered seabed.
When Larsen B broke away, the immediate investigation chanced upon new species.
Under the Antarctic Treaty, no fishing activity would be permitted in the area for 10 years.
The big bergs that break away from Antarctica are monitored from space.
They will often drift out into the Southern Ocean where they can become a hazard to shipping.
The biggest iceberg recorded in the satellite era was an object called B-15.
Covering an area of some 11,000 sq km, it came away from the Ross Ice Shelf in 2000.
Six years later fragments of the super-berg passed by New Zealand.
In 1956, a berg of roughly 32,000 sq km - bigger than Belgium - was spotted in the Ross Sea by a US Navy icebreaker. But there were no satellites at that time to follow up.
Many of the bergs that break away from the Weddell Sea area of Antarctica get exported into the Atlantic. A good number get caught on the shallow continental shelf around the British overseas territory of South Georgia where they gradually wither away.
The study of the Larsen C Ice Shelf is led by Swansea University through its MIDAS Project, which involves BAS.

The BBC has commissioned full series of the revival of Porridge and new parenting comedy Motherland.

Six new episodes of Porridge, starring Kevin Bishop, will be made after a pilot episode received warm reviews.
The remake of the 1970s show, which saw Bishop play the grandson of Ronnie Barker's inmate Fletch, was part of the BBC's sitcom season.
Motherland was part of "New on Two", which saw several new sitcoms piloted on BBC Two.
Porridge creators Dick Clement and Ian La Frenais, who will write the new BBC One series, said: "We're in a state of disbelief that Porridge is coming back after all these years, but Kevin Bishop is a worthy successor to Ronnie Barker.
"So even though we feel like recidivists, we're more than happy to go back inside."
Bishop said: "It was an honour to be asked to play Fletch although I never thought it would go further than just the one-off homage.
"To be welcomed back by Porridge fans and the BBC to make a full series, is one of the proudest moments in my career."
Last month, 4.4 million viewers tuned in to the new episode of Porridge, which received broadly positive reviews.
The Telegraph's Michael Hogan said Porridge "left me with an indulgent grin on my face", while The Daily Mail described it as "an affectionate tribute to a magnificent series, by the men who created it".
The original series of Porridge, which saw Barker and Richard Beckinsale appear as two inmates at the fictional HMP Slade prison in Cumberland, ran from 1974 to 1977.
More than two million viewers watched the pilot episode of Motherland across all platforms and the comedy - starring Anna Maxwell Martin as a harassed parent - was praised by critics.
The Guardian described Motherland as "terrific" while The Independent called it "a magnificent half-hour of fresh comedy".
The pilot episode was written by Graham Linehan, Helen Linehan, Sharon Horgan and Holly Walsh.
As the full BBC Two series was announced, Catastrophe star Horgan said: "I am thrilled and relieved to have finally found a good use for my 13 years of mothering.
"Apologies in advance to the brave women and men of the school run."
Six 30-minute episodes will be made both of Motherland and Porridge.
Broadcast dates for both shows are yet to be announced, but Porridge will go into production in January.
The BBC also announced that a series of A Brief History of Tim, written by and starring Tim Renkow, had been commissioned.
Renkow, who has cerebral palsy, plays the lead role in the comedy which sees his character use his condition to get away with saying whatever he wants.
Four 22-minute episodes of A Brief History of Tim will be made for BBC Three, which moved online earlier this year.
Renkow said: "I'm very excited to be working with the BBC. I just hope I can beat my old employment record of two days."
Damian Kavanagh, controller of BBC Three, said: "We are all about the best new British comedy at BBC Three and are very happy to give A Brief History of Tim a home."
Shane Allen, the BBC's controller of comedy commissioning, said: "These three exciting new commissions reinforce our mission to keep nurturing the very best of new talent and to cherish the great talents we've championed over the years."

A former KGB officer suspected of killing Alexander Litvinenko says he will not attend the UK inquest into the Russian spy's death.

Russian MP Andrei Lugovoi told a Moscow press conference he could not receive "justice" in Britain.
Mr Litvinenko, 43, died in 2006 after he was poisoned with polonium-210 while drinking tea at a London meeting.
A pre-inquest review heard he was working alongside Spanish spies for MI6 in the days before his death.
Russia has refused to extradite Mr Lugovoi to the UK for questioning. He has also denied any involvement.
It was thought he might have provided video-link evidence to the inquest in London.
But a spokesman for the inquest said: "It is too early to say whether Mr Lugovoi will be called to give evidence and, if he is, how it would be given."
Mr Lugovoi reportedly told the press conference, which was hosted by the Russian news agency, Interfax: "I have no hope to get justice in the UK. I finally lost faith in the possibility of an impartial investigation of the case...
By Steven RosenbergBBC News
Andrei Lugovoi was almost mocking in his criticism of Scotland Yard and the British government at the press conference. He condemned the 'politicised fantasy of London detectives' who had written 'drivel' in their report into Alexander Litvinenko's death.
The last hitmen the Russian state had despatched abroad to murder political opponents had been, he said, in Stalin's time.
Mr Lugovoi presented himself as totally innocent, a crusader for transparency and justice. He was even prepared, he said, to travel to London - but, crucially, only after the accusations against him are dropped. Lugovoi knows they won't be, so a trip to Britain in the near future seems out of the question.
Russia has refused to extradite him. What's more, Moscow has given the distinct impression it has been trying to protect him.
A year after Alexander Litvinenko's death, Mr Lugovoi was included in the party list of a Russian nationalist party. He was duly elected to the State Duma and received parliamentary immunity from prosecution.
"I have to say that I'm out of the coroner's investigation and I will not participate in it."
It has been claimed that Lugovoi and another former KGB agent, Dmitry Kovtun, poisoned Mr Litvinenko at the Millennium Hotel in London's Grosvenor Square.
The inquest is due to formally open on 1 May.
Last month, coroner Sir Robert Owen ruled that sensitive evidence alleged to expose Mr Litvinenko's ties to MI6 will be examined in secret.
He has said he will examine what was known of threats to Mr Litvinenko's life and also whether the Russian state was responsible for his death.
He has also agreed that a group representing Russian state prosecutors can be accepted as a party to the inquest process, which would allow it to cross-examine witnesses and examine evidence.
British Government documents that implied Russia was behind the 43-year-old's death were also revealed. Moscow has denied any involvement.
Sir Robert will also hold a hearing on Thursday, in which he will hear applications for anonymity of witnesses and will consider submissions on the inquest timetable.


Created in 1960 from a former British protectorate and an Italian colony, Somalia collapsed into anarchy following the overthrow of the military regime of President Siad Barre in 1991.

As rival warlords tore the country apart into clan-based fiefdoms, an internationally-backed unity government formed in 2000 struggled to establish control, and the two relatively peaceful northern regions of Somaliland and Puntland effectively broke away.
The seizure of the capital Mogadishu and much of the country's south by a coalition of Islamist shariah courts in 2006 prompted an intervention by Ethiopian, and later, African Union, forces.
Since 2012, when a new internationally-backed government was installed, Somalia has been inching towards stability, but the new authorities still face a challenge from Al-Qaeda-aligned Al-Shabab insurgents.
Population 10.8 million (UN, 2015)
Area 637,657sq km (246,201 sq miles)
Major languages Somali, Arabic, Italian, English
Major religion Islam
Life expectancy 54 years (men), 57 years (women)
Currency Somali shilling
President: Mohamed Abdullahi Mohamed
Mohamed Abdullahi Mohamed, also known as Farmajo, was elected by MPs gathered under tight security in a hangar at the airport of the capital Mogadishu in February 2017.
The dual US-Somali citizen served as prime minister for eight months between 2010 and 2011 when he gained popularity by ensuring regular payment of army salaries and implementing a biometric register for security personnel.
He has expressed readiness to talk to the Islamist al-Shabab militants.
Somalia's disintegration is reflected in its fragmented and partisan media, which operates in a hostile environment.
Journalists and media outlets complain about intimidation at the hands of state security agencies. Nevertheless, professionally-run media outlets have emerged - in particular, FM radios with no explicit factional links.
The TV and press sectors are weak and radio is the dominant medium. Domestic web access is held back by poor infrastructure, but social media use is on the rise.
7th-19th centuries - From the 7th-century arrival of Islam onwards, modern-day Somalia is ruled by a series of at times competing sultanates.
19th century - European colonial powers gradually make inroads into Somalia's rival regional states, with the bulk of the area coming under Italian rule and the British establishing control of the northwest.
1960 - Italian Somaliland and British Somaliland become independent, merge and form the United Republic of Somalia.
1969 - Mohamed Siad Barre assumes power in coup after the assassination of the elected president; he goes on to declare Somalia a socialist state and nationalises most of the economy.
1991 - The ousting of Mohamed Siad Barre in 1991 sparks a decades-long civil war between rival clan warlords and the disintegration of central authority. Former British Somaliland declares unilateral independence.
1990s- US-spearheaded UN peacekeeping mission fails to restore peace. Northern Puntland region declares autonomy in 1998.
2005-2012  Pirates - mainly operating out of Puntland - pose a major menace to shipping off the Somali coast, before falling away as a threat as a result of an international naval operation.
2006 - Militias loyal to the Islamist Union of Islamic Courts capture Mogadishu and other parts of south after defeating clan warlords, before being driven out by Ethiopian forces.
2007-11 - An African Union peacekeeping force, Amisom, begins to deploy and Ethiopian troops withdraw in 2009. Al-Shabab - a jihadist breakaway from the Islamic Courts - advance into southern and central Somalia, prompting an armed intervention by Kenya.
2012 - Efforts to restore a central authority since 2000 finally make substantial progress, with the swearing in of the first formal parliament in more than 20 years, and the holding of the first presidential election since 1967. Pro-government forces make key advances against Al-Shabab militants.


Opposition parties have called for answers after it was revealed a newspaper firm cutting jobs in Newport was given more than £340,000 grant aid.

The Welsh Government gave Newsquest £245,000 in 2015 to expand a sub-editing hub now closing with the loss of 14 jobs, with work moving to Dorset.
In 2013-14 the company got more than £95,000 from the Skills Growth Fund.
Plaid Cymru asked if the firm "stuck to their end of the bargain" while a Tory AM asked if the money should be repaid.
Newsquest, whose papers include the Newport-based South Wales Argus, opened the sub-editing hub in 2013.
At its peak the unit employed more than 70 people, checking off material written by reporters from 100 daily and weekly newspapers across the UK.
After two rounds of job cuts in 2016, the hub will now close in April, with work moving to Weymouth, Dorset.
Earlier this week, a Newsquest spokesman said the workload had reduced "significantly" due to an "improvement in workflow across all of our newsrooms".
Asked about the grant aid, the Welsh Government spokesman said: "In 2015 we provided £245,808 to Newsquest towards the creation of 50 jobs and the safeguarding of 15 jobs at its facility in Maesglas, Newport.
"The award was conditional on the jobs being in place until May 2020. This operation well exceeded its planned job creation target.
"We were very sorry to hear that Newsquest decided to undertake several rounds of redundancies at the operation during 2016, which has seen staffing levels reduce significantly.
"The group continued to employ a significant number of staff at the site for other related group editorial services.
"We are aware of this fresh report of further redundancies," the spokesman added.
"We are seeking confirmation from the company and will be reviewing the staffing levels at the site in relation to their funding conditions in due course."
The Welsh Government confirmed Newsquest also received support under the Skills Growth Wales programme in 2013/2014, claiming £95,226.72.
Plaid Cymru AM Bethan Jenkins, who chairs the assembly's culture committee, was "very concerned", saying: "It seems that again, we have a company which has happily received public money and not stuck to their end of the bargain.
"This has come out of the blue and will be another blow to our news media industry in Wales, at a time when it's already under pressure."
For the Conservatives, South Wales East AM Mohammad Asghar said:  "Taxpayers will be looking to the Welsh Government to provide assurances that this isn't more money down the drain.
"Because if Newsquest has breached assurances it gave over jobs when applying for these grants then the money will need to be paid back.
"Sadly, this is also a blow for journalism in this country, with more and more of the physical capacity being drained away from Wales and piling up the pressure on the industry."
John Toner, national organiser for Wales of the National Union of Journalists, said: "This company is not a struggling start-up, but a major player in this country and in the USA.
"Why did it feel the need to apply for government funding?
"Newsquest owes an apology to the Welsh Government and to Welsh taxpayers."
A Newsquest spokesman said: "We are in constant discussions with the Welsh Government."


Deputy Prime Minister Nick Clegg has had to clarify the government's position on the Iraq war after telling MPs the conflict had been "illegal".

At prime minister's questions, Mr Clegg said Labour's Jack Straw would have to account for his role in the "disastrous" decision to invade.
Mr Clegg later stressed his opinion was a "long-held" personal one.
Foreign Secretary William Hague, who backed the war, said his history on the issue was "different" to Mr Clegg.
As regards the government's official position on the legal basis for war, a spokesman for the deputy prime minister said "it awaits the outcome" of the Chilcot inquiry looking into the background to the war.
"The deputy prime minister was expressing his long-held view about the legality of the Iraq conflict," he added.
"His views on the matter are very well known and widely documented."
The Conservatives backed the then Labour government's decision to commit troops to Iraq in 2003, with current key figures such as Mr Hague, Prime Minister David Cameron and Chancellor George Osborne all supporting the war.
The Lib Dems, led at the time by Charles Kennedy, opposed the war and have consistently questioned its legality.
Lord Goldsmith, attorney general in the run-up to the war, has said he advised ministers that it was lawful on the basis of Iraq's failure to comply with existing UN resolutions on disarmament dating back to 1991.
In his first appearance at prime minister's questions, Mr Clegg told Mr Straw - himself filling in for acting Labour leader Harriet Harman - that he was happy to "account for everything we are doing in this coalition government".
He added: "Maybe he one day - perhaps we will have to wait for his memoirs - could account for his role in the most disastrous decision of all, which is the illegal invasion of Iraq."
As foreign secretary in the run-up to the war, Mr Straw was a crucial figure in backing the conflict and he told the Iraq war inquiry earlier this year that the UK could not have committed troops without his support.
Mr Hague, who was not in the shadow cabinet in 2003 but voted in favour of the war, distanced himself from Mr Clegg's comment later on Wednesday during a statement in Parliament on Afghanistan.
"The deputy prime minister has a different history from mine on that subject," he said in answer to a question from Labour MP David Hanson.
"That is certainly true."
It was up to ministers who were in power at the time "to account for their actions", he added. Mr Clegg was not an MP at the time of the war.
The Chilcot inquiry is continuing to examine the background to the UK's participation in the 2003 conflict and its aftermath.
However, it is not clear whether the inquiry, whose remit is to "establish, as accurately as possible, what happened and to identify the lessons that can be learned", will draw specific conclusions on the legal basis for the invasion.
Several witnesses, including former minister Clare Short, have taken issue with the war's legality.


A Conservative councillor who wrote a racist tweet during the Eurovision Song Contest has resigned.

Nick Harrington, who sat on Warwick District Council, has apologised for causing "considerable offence to both members of the traveller community and to those of Irish heritage".
He also apologised to athlete Christine Ohuruogu for an "ill-judged" comment he made last year on Facebook.
He has already quit as a magistrate.
In the tweet Mr Harrington made during Eurovision, he said that Ireland could keep its gypsies, using strong language.
In the post on Facebook, he likened Ohuruogu to a black scarecrow.
In a statement in which he apologised "unreservedly", he said: "My comments about the Irish border were also foolish.
More updates on this story
"In addition there have been comments about my Facebook post of an entry in a scarecrow competition last year which was based on the Olympics. I accept this was ill-judged for which I apologise to Christine Ohuruogu.
"Therefore it is with deep regret that I formally tender my resignation as member for Stoneleigh and Cubbington ward effective immediately."
He added he was "devastated" by what he had done.
Mr Harrington's Twitter account was deleted after the Eurovision furore but his remarks were widely retweeted.
Police are investigating and are treating what happened as a suspected hate crime.
Council leader Andrew Mobbs initially suspended Mr Harrington for six months, saying his behaviour was unacceptable.
He said on Wednesday that his resignation was "entirely appropriate" and he awaited the outcome of a police investigation.
"I am very disappointed that his comment was made in the first place and by the reaction it generated towards the district council on social media," he added.


The UK is to spend £25m on building a prison in Jamaica so that foreign criminals in the UK can be sent home to serve sentences in the Caribbean.

Prime Minister David Cameron announced the deal as he started a Jamaica visit.
The project has been agreed to break the deadlock in negotiations over a prisoner transfer deal between the two countries.
More than 600 Jamaican nationals are in UK jails but cannot be deported because of Jamaica's poor prison conditions.
Officials say the foreign aid-funded deal could save taxpayers £10m a year when transfers begin in 2020.
More than 300 existing offenders are expected to be sent back under the Jamaica prison scheme, which covers those sentenced to at least four years who have 18 months or more left to serve in custody.
Currently they cannot be sent to Jamaica because of fears that jail conditions in the country would allow a successful challenge under human rights law.
Jamaica is third highest in the list of foreign countries with nationals serving prison sentences in the UK..
Almost 70% of the Jamaicans in prison in Britain are serving sentences for violence and drug offences.
The UK is contributing about 40% of the cost of building the planned jail, which would hold 1,500 people.
Mr Cameron, who had been at the United Nations in New York for talks on the fight against the Islamic State group, said: "It is absolutely right that foreign criminals who break our laws are properly punished but this shouldn't be at the expense of the hard-working British taxpayer," he said.
"That's why this agreement is so important. It will mean Jamaican criminals are sent back home to serve their sentences, saving the British guard of honourtaxpayer millions of pounds but still ensuring justice is done.
"And it will help Jamaica by helping to provide a new prison, strengthening their criminal justice system."
Mr Cameron, the first British prime minister to visit the island in 14 years, is also set to announce £300m of aid funding on infrastructure projects across the Caribbean, including roads, bridges and ports.
He said the regional infrastructure fund, which will be delivered in collaboration with the Caribbean Development Bank, would help support economic growth in the Caribbean.
Mr Cameron was greeted on his arrival at Kingston Airport by an honour guard and national anthems before he visited RFA Lyme Bay, the British ship currently on anti-drug smuggling and emergency relief duties in the Caribbean.
He is due to finish the day by having talks with Jamaican Prime Minister Portia Simpson-Miller and attending a reception.
BBC political correspondent Carole Walker says that the PM has said he wants to improve a neglected relationship between the UK and Jamaica.


A Scottish man with multiple sclerosis said he was "overwhelmed" by the reaction to a video he posted shaming two men who made him feel "less human".

James Johnston's Facebook video about the incident at the Fort Shopping Centre in the east of Glasgow has been watched more than 800,000 times.
The 27-year-old told the Kaye Adams programme the men had been rude and ignorant and made him feel "rotten".
He said the reaction to the video had been "absolutely fantastic".
James, from Bellshill in Lanarkshire, was diagnosed with multiple sclerosis three years ago.
In the video he is visibly upset as he describes how the men laughed as he tried to pick up his phone from the ground.
James told the Kaye Adams programme it all began when he was rushing to the toilet at the shopping centre and he overtook the men.
He said: "I can't walk in a straight line because of the MS. I'm walking as fast as I can and I feel as though my legs are actually going to give way."
James said he was aware that he "staggers" when he walks and it makes him look drunk.
He said he was used to people staring and his main aim was to reach the toilet in time.
"There is nothing more demeaning than wetting yourself, especially at 27," he said.
When he walked out of the cubicle one of the men he had seen before walked into the toilet, but James ignored him.
"I walked out into the lobby outside the toilets and this guy was looking at his phone and I noticed him looking at me," he said.
"He had a disgusted look on his face."
James tried to phone his partner but she didn't answer. He then saw his step-daughter outside a shop and he tried to get her attention but dropped his phone.
Because he has very little sensation in his fingers he had trouble picking it up.
"These two same guys, one of them stepped over the phone and went 'oops' and the two of them sniggered.
"Fair enough, they didn't know I had got a disability but at the same time, manners don't cost anything."
James said: "I usually just ignore it but this was the straw broke the camel's back. You get used to the stares but you should not need to.
"What they did was rude and ignorant."
He says he posted the Facebook video to raise awareness and to shame the two men, who he hopes might see it.
"It's trying to get across to people don't judge a book by its cover," he said.
"It made me feel less human.  I just felt rotten.
"We left the Fort after that. I just said I don't want to be here."
When he got home he posted the video expecting to get a few hundred views.
"It has gone nuts," he says.
"I'm overwhelmed by it because I really didn't expect the feedback that I have got.
"About 99.9% has been absolutely fantastic. There are a couple of people who maybe are ignorant."
Before he was diagnosed with MS, James used to drive buses.
He said finding out he had the condition was "heartbreaking" and admits that he had been ignorant about MS before he was diagnosed.
But he said having the condition was bad enough without the stigma that came with it.
Rebecca Duff from the MS Society: "Unfortunately James's story is not unique.
"We did a survey last year around stigma and about half of the people we surveyed had been accused of being drunk. They'd also been challenged about parking in a disabled parking bay.
"A lot of symptoms of MS are maybe not visible. It is not always about a wheelchair."
James said he was trying to remain independent and last year went to Cuba on his own for a holiday.
"I'm living my life more now than I was three years ago," he said.


An elderly man who had to be airlifted from a cruise ship after he fell ill with Legionnaires' disease has received a five-figure out-of-court settlement.

Frank Standen, 84, of Tunbridge Wells, Kent, started suffering from symptoms days into a trip from Southampton to Cape Verde in November 2011.
He was initially treated by the ship's doctors but flown to hospital on Gran Canaria when his condition worsened.
Fred Olsen said there was no evidence he contracted the illness on board.
After he was airlifted from the cruise ship Black Watch, Mr Standen spent seven weeks in hospital in Las Palmas de Gran Canaria and then a further five weeks at Sevenoaks Hospital.
He said the whole experience for he and his wife Patricia, 83, was "absolutely terrible" and he was delighted to have received a settlement from Fred Olsen.
"I feel really lucky to be alive but the whole experience of the cruise, being airlifted from the ship and spending so much time in hospital was absolutely dreadful and really shook me up.
"Myself and Patricia did not get to enjoy our cruise and instead of being at home with my family over Christmas I was in hospital in a foreign country."
Irwin Mitchell lawyer, Clare Pearson, who represented the couple said it was "disappointing that the cruise operator denied liability" and waited until the case was due to go to trial before agreeing payment.
In a statement, Fred Olsen Cruise Lines said it was "very sorry that Mr Standen was seriously unwell" but denied liability for his illness.
"As soon as his symptoms were discovered our ships doctors and nurses did everything possible to ensure he received the best treatment. They quickly identified that Mr Standen would need to be taken to hospital and the ship arranged for a helicopter evacuation," it continued.
"Despite thorough and extensive testing there is no evidence to suggest that he contracted Legionnaires' disease on board our ship. No other guests or crew were found ill on this or any other subsequent cruise."
Legionnaires' is a form of pneumonia which is most often contracted by inhaling mist from water.


Skeletons unearthed in London Crossrail excavations are Black Death victims from the great pandemic of the 14th Century, forensic tests indicate.

Their teeth contain DNA from the plague bacterium Yersinia pestis and their graves have been dated to 1348-50.
Records say thousands of Londoners perished and their corpses were dumped in a mass grave outside the City, but its exact location was a mystery.
Archaeologists now believe it is under Charterhouse Square near the Barbican.
They plan to expand their search for victims across the square - guided by underground radar scans, which have picked up signs of many more graves.
Crossrail's lead archaeologist Jay Carver says the find "solves a 660-year-old mystery".
"This discovery is a hugely important step forward in documenting and understanding Europe's most devastating pandemic," he said.
"Further excavations will follow to see if - as we expect - we are coming across a much bigger mass burial trench."
Between 1347 and 1351 the "Great Pestilence" swept westward across Europe killing millions of people. It later became known as the Black Death.
It arrived on Britain's shores in 1348 and is believed to have wiped out up to 60% of the population at the time.
In London, two emergency burial grounds were dug outside the walls of the City. One has been found at East Smithfield, while the other is known to lie somewhere in Farringdon.
In March 2013, Crossrail engineers uncovered 25 skeletons in a 5.5m-wide shaft - alongside pottery dated to the mid-14th Century.
Samples from 12 of the corpses were taken for forensic analysis. In at least four cases, scientists found traces of the DNA of the Yersinia pestis, confirming they had contact with the plague prior to their death.
To pinpoint which historical plague outbreak the "Charterhouse 25" could have fallen victim to, the researchers used radio carbon dating.
They determined the burial ground was used in at least two distinct periods - the earliest within the Black Death in 1348-50, followed by a later outbreak in the 1430s.
In a bid to understand just how far the grave extends across the square, Crossrail approached the University of Keele to undertake a forensic geophysics survey - using ground-penetrating radar.
The initial scan detected signs of further burials across Charterhouse Square and also the foundations of a building - possibly a chapel.
"We will undertake further excavations in Charterhouse Square later this year to confirm some of the results," said Mr Carver.
The skeletons provide a rare opportunity to study the medieval population of London, according to osteologist Don Walker, of the Museum of London Archaeology.
He said: "We can start to answer questions like: where did they come from and what were their lives like?
"I'm amazed how much you can learn about a person who died more than 600 years ago."
Analysis of the skeletons' bones and teeth indicates that:
Mr Carver said: "We can see from the people here that Londoners weren't living an easy life.
"The combination of a poor diet and generally a struggle means they were very susceptible to the plague at that time and that's possibly one of the explanations for why the Black Death was so devastating."
By sequencing the ancient bacterial DNA, researchers hope to understand how the plague has evolved and spread over the centuries.
Globally the infection still kills 2,000 people a year, including countries like Madagascar. Antibiotics are available, but if untreated the disease kills within four days.
Scientists hope to confirm whether the 14th Century strain was the grandmother of all plague that exists today.
The £14.8bn Crossrail project aims to establish a 118km-long (73-mile) rail link with 37 stations across London, and is due to open in 2018.
The excavations have already unearthed Roman skulls washed down a lost river, a Bronze-Age transport route, and the largest piece of amber ever found in the UK.
The latest announcement comes ahead of a Channel 4 documentary, Return of the Black Death: Secret History, on 6 April, which follows the Charterhouse Square discovery.


The risks to a vulnerable man who was tortured and murdered were known three years before his death, a report says.

Lee Irving, 24, who had learning disabilities, was killed by people he thought were his friends in Newcastle in 2015.
While the review said it was unclear if Mr Irving's death could have been prevented, it said public bodies struggled with his "chaotic lifestyle".
Four people were jailed over his murder in December 2016.
Mr Irving was found dead near a footpath in June 2015. He had suffered multiple injuries, including 27 rib fractures.
A Safeguarding Adults Review revealed that since the age of four, 14 agencies had been involved with Mr Irving, who had an IQ of 56 and a history of offending.
Report author Tom Wood said public bodies, including Newcastle City Council, the probation service and Northumbria Police, struggled with Mr Irving's "chaotic lifestyle" and that he only attended about 50% of appointments.
In 2001, the National Probation Service (NPS) assessed Mr Irving as being "incredibly vulnerable to the influence of others" and was willing to be bullied rather than be "rejected by his peers".
The report said: "With the knowledge we have about the death of Lee Irving the pinpoint accuracy of the NPS assessments makes it clear that Lee's problems and vulnerability were known to the fullest extent three years before his death.
"It is, however, notable that even following the NPS assessment no alarm was raised or safeguarding alert instigated by the NPS."
The review highlighted failures of agencies to share information, a reluctance to challenge Mr Irving's lifestyle and a failure to involve his family in decisions about his future.
Mr Wood concluded: "Many individuals and agencies tried hard to engage with Lee Irving. He was difficult to help and while lacking the capacity to make some decisions in his own interest he seemed determined to exercise his own autonomy which sometimes placed him at risk.
"Whether any of these changes would have saved the life of Lee Irving will never be known."
Ewen Weir, director of people at Newcastle City Council, said: "While all agencies tried to engage with Lee, there was insufficient challenge and support among partners.
"I know that Lee's family felt excluded from some of the decisions that were taken about his care and that their warnings about his living conditions were not acted upon effectively. For that we are truly sorry."
Chair of the Newcastle Safeguarding Board, Vida Morris, said: "Lee was a vulnerable adult whose death was an evil act carried out by people who acted inhumanely.
"Although his case was not legally a disability hate crime, it is our opinion that it is still appropriate to view his death as connected or motivated by his disability."
A spokesperson for NPS said: "This is a tragic case and our thoughts are with the family and friends of Lee Irving.
"We will carefully consider the findings of this review to identify any lessons that can be learnt."


If you were going to use art as a form of protest, would you (a) drop an unannounced album on Tidal accompanied by a one-hour special on HBO, or (b) nail your genitals to a paving stone?

I (like you, I'm guessing) would go for A. But that's not an option. We are not Beyonce (when your name auto-corrects on Word, you know you've made it).
If we're hacked off about something important - say, the state of the nation (the real subject of Lemonade) - then what can we do that would have anything like the effect of Ms Knowles-Carter's latest creative endeavour?
Well…there is the unedifying, and let's face it, potentially very painful prospect of nailing your parts to a pavement.
I'm not advocating this as a course of action, and certainly won't be pursuing it myself, but it has proven potency.
Petr Pavlensky is a Russian artist at the radical, Dadaist, end of the spectrum. His reference points include Guy Debord's Situationist International movement, the Sex Pistols and Kazimir Malevich - and less obviously, Lucien Freud and Caravaggio.
He, like Beyonce, thinks there's room for improvement in the way in which his country is run.
He too thinks there is oppression, police brutality, and corporate/state corruption. But he doesn't have access to the sort of levers available to the US singer, and even if he did, I doubt he'd pull them in quite the same way.
In fact Mr Pavlensky doesn't have access to a great deal. His work as a political artist doesn't pay well (it doesn't pay at all). Not in a material sense, anyway. But it does provide him with a return on his intellectual and physical investment.
It gets his work noticed and talked about across the world while shedding light on his chosen subject (state authoritarianism).
Briefly. He started out at art school, but found the teaching dogmatic and dull.
He left and found his artistic voice by sowing his mouth shut in response to the incarceration of members of Pussy Riot following the performance of their Punk Prayer in the Cathedral of Christ the Saviour in Moscow.
It made for a strikingly nasty image. An image, that had it been made by a non-artist, would have received little attention, but by pulling the one lever had got - art - his work received international attention.
He followed that up with a piece called Fixation (2013). That's the one where his genitals come in to play.
After weeks of preparation and planning, he went to Red Square, stripped naked, and nailed his scrotum to the paving stones. Extreme? Yes, very. But maybe extreme situations call for extreme actions?
That seems to be the view and aesthetic of the Moscow-based Voina movement, to which you could argue his work belongs: as well as being a development from that produced by the Moscow Conceptualists of the '70s and '80s.
In November last year he made Threat (2015), an action-performance that involved his dousing the huge, imposing doors of the Lubyanskaya Ploshchad - the HQ of Russia's Federal Security Service (FSB) - in petrol and setting fire to them.
The artist then stood in front of the burning entrance and posed for the photographs that would be disseminated around the world. People took notice, learnt about the FSB, and heard what he had to say - although he said nothing.
Unsurprisingly, he was arrested - I can't think of a country where he wouldn't have been - and is currently standing trial.
If he is found guilty, his alleged crime carries a maximum jail sentence of three years (less the time in detention he has already spent since November).
Serves him right, some might say. Maybe, even him. His art is about provocation, after all. The arrest, trail and subsequent spell in jail are all part of the artwork as far as he is concerned.
Ai Weiwei uses the notion of art in a similar way. He too turns himself into a one-man picket to bring attention to what he perceives as the shortcomings of the authorities in his native country, China.
He has also been incarcerated, although for far less obvious reasons.
The American Theaster Gates is another artist who "leverages" the status of art in society to turn the detritus he finds in the dilapidated buildings he buys on the Southside of Chicago into sculptures worth hundreds of thousands of dollars.
He then uses the money to help regenerate the area, which has been called the murder capital of America.
My point is, what Mr Pavlensky is doing might seem totally crazy, but it does sit within a current agit-art movement that has a vitality and purpose which is a long way from much of the derivative commercial fare served up in the Truman Show-like world of white-walled museums and galleries.
He is furious. Ai Weiwei is furious. Theaster Gates is furious. Beyonce is furious.
They are all using art to protest, and to some effect - but admittedly with different immediate outcomes.
Beyonce is about to embark on a world tour, while Pyotr Pavlensky may face a three-year stint in jail.

Tommy Hilfiger has said suggestions he thought Gigi Hadid was not thin enough to model are "completely false".

The fashion designer had told Yahoo that casting directors dressed Hadid in a poncho for a fashion show because she was not as thin as the other models.
But he has now clarified his comments and said the story was misleading.
Hilfiger said: "The suggestion that I thought [Hadid] wasn't thin enough upsets me to no end. Gigi is the epitome of perfection."
In the Yahoo interview, Hilfiger referred to a 2015 fashion show in which Hadid wore a poncho which covered most of her body.
Hilfiger said he wanted Hadid to be dressed in something which better showed off her figure, but members of his creative team disagreed.
"Our casting director said, 'She doesn't really fit because you know she's not quite as tall as the other girls, she's not quite as thin,'" Hilfiger originally said.
"So they put a red, white, and blue poncho on her. It covered a lot of her body unfortunately, but it received millions of hits."
Hadid's appearance in the poncho proved hugely popular, and she later went on to collaborate with Hilfiger, launching her own line of clothing for the brand earlier this year.
After Hilfiger's comments sparked criticism, the designer criticised the original story's headline as "misleading".
Speaking to Page Six, Hilfiger said: "The casting people put Gigi in the poncho, and I was not happy.
"I was saying, 'Don't hide her body.' Even though the poncho ended up being the best-selling piece, I was very unhappy."
The designer also released a statement to Entertainment Tonight, in which he said he was "extremely proud" to have Hadid representing his brand.
"Gigi is truly the definition of a 'Tommy Girl' - her magnetic personality is bright, confident and always optimistic," he said.
"I've known her for many years, and am extremely proud to have her as the ambassador of my brand and as a collaborator of our collections.
"Any statement to the contrary is completely false. The headline from the interview with Yahoo was misleading and has since been corrected."

Former Newcastle United footballer Nile Ranger has been cleared of rape, following a week-long trial.

The 22-year-old, who now plays for Swindon Town, had denied the charge, claiming the woman had consented to sex at a hotel in January 2013.
Newcastle Crown Court heard the woman had agreed to meet him after the pair had swapped a number of messages.
The player told the court he had never engaged in sexual activity with a female against her will.
During the trial, the jury heard Mr Ranger and the woman had met in a city centre bar and gone on to different clubs before eventually booking into the Carlton Hotel, in the Jesmond area of Newcastle.
Giving evidence, the woman said she had no memory of the night beyond the bar where they met, until she woke up naked next to the footballer in bed.
The jury took an hour to reach their not guilty verdict, after which Mr Ranger banged on the glass door of the dock and said: "Thank God for that."
He then thanked the jury and, as he removed his tie, said "What a joke" before leaving court with friends.
Previously, the trial had heard that after spending the night with the woman, the player told her she should take the morning after pill.
She left and they continued to swap messages that day, the court was told.
She then visited her GP, was checked at hospital and made a rape allegation to police.
After being arrested Mr Ranger told police the pair had sex more than once and that she had engaged "whole heartedly" and "enthusiastically".
The court heard they had been messaging for a year before the incident, with the player repeatedly trying to meet up with her.
This had led the woman to refer to him as a "predator" and "Nile Ripper" in some of the texts they exchanged, the jury learned.
Mr Ranger made no comment on leaving the court but his solicitor, Geoffrey Forrester, said the footballer was delighted with the outcome.
During the trial the jury heard about trouble that Ranger had been in previously.
This included serving an 11-week sentence in a young offenders' institution when he was 15 after he took part in a street robbery.
Growing up in North London, he mixed with an older gang and also had convictions for burglary and handling stolen goods in 2007.
While giving evidence, Mr Ranger said his rape arrest was "one of the main reasons" his contract was terminated with Newcastle United.
The player told jurors he was about to be transferred to Hull City on loan from Newcastle when the rape allegation was made.
He said his contract with the club, and the loan arrangement, ended after his arrest.
He then moved to League One side Swindon Town where, he told the court, he had enjoyed success on the field.
The Wiltshire club said: "At this point the club is not making any comment."


Two men have been arrested by police in connection with a disturbance in Chambers Street in Edinburgh.

The incident happened earlier outside an Edinburgh University building where a student occupation is underway.
A report will be sent to the procurator fiscal. It follows footage posted on social media showing an altercation between a security guard and a student.
The university said it "deeply regretted the unfortunate incident".
About 30 students have been occupying a university building in protest at its "failure to commit" to divestment from fossil fuels.
Eric Lai, one of the occupiers inside, said: "We have been repeatedly told that the university supports our right to protest, but that couldn't feel further from the truth."
"The university have posted dozens of guards to the doors, and have now taken to intimidation and violence to shut us up. It is hard to imagine a more inappropriate way to handle student protest."
"The university need to immediately change their approach, allowing open access to the building and engaging with the politics of why we're here, rather than just covering their ears to both the demands of students and staff, and the desperate urgency of tackling climate change.
"Until they move their money out of fossil fuels, we're going nowhere."
An Edinburgh University spokesman said: "The university is aware of, and deeply regrets, the unfortunate incident that is currently being played on social media.  The matter is now in the hands of the police.
"We continue to support the right of students to peacefully and lawfully demonstrate and the University is using private security outside its buildings in Chambers Street in order to secure the safety of staff and students during the occupation."
"We are constantly reviewing our security arrangements to make sure that they are appropriate to the circumstances in what is an evolving situation."


A man who beat his brother-in-law to death with a mallet and an axe in West Lothian has been convicted of murder.

Jimmy Smith, 58, said he acted in self-defence when Alexander Cameron, 67, attacked him and threatened to shoot his wife Helen Smith on 19 January.
He tried to cover up the crime by burying Mr Cameron's body under a pile of horse manure at West Cairns Farm, Kirknewton.
Smith was found guilty of murder by a jury at the High Court in Livingston.
They also convicted him of attempting to defeat the ends of justice by concealing the body and pretending to police he did not know where the missing man was.
Smith had admitted killing Mr Cameron by repeatedly striking him on the head with a log-splitting axe and a six-kilo fencing hammer and burying the body in a shallow grave.
But he had denied the crime was murder.
Judge Lord Matthews told Smith he would be sentenced at the High Court in Edinburgh on 4 August.
Smith said he feared he was going to be killed when Mr Cameron ran at him swinging a bag at his head.
He said he fell over trying to avoid being struck, grabbed "two large hammers" and swung one of them around onto the back of Mr Cameron's head.
His typewritten confession read: "Pulling myself up I then went into a frenzied sort of numbness and was striking him several times on the head. All that I can remember thinking was: 'I can't let him shoot Helen."
Mr Cameron's body was later exhumed from the shallow grave where it had been concealed under paving slabs and a pile of horse manure.
His wrists and ankles had been bound together with electrical flex and blue polypropylene rope and his head and face were covered in blood from "blunt force trauma" caused by being hit with a sledgehammer and an axe.
Consultant pathologist Dr Robert Ainsworth said Mr Cameron had probably died very soon after suffering the principal injury, which crushed the top of his skull and may have caused his spine to snap.
Forensic scientist Juliet Riches said swabs from the handle of the weapon proved a match for the DNA of the accused Smith, and blood spots matching the DNA of Mr Cameron were found near the head of the axe and on the sledgehammer.
The court heard that Mr Cameron had links to various serious and organised crime groups in Scotland's Central Belt and connections "to do with Liverpool gangs".
He had been sentenced to six years in prison in 2011 for being concerned in the supply of controlled drugs after a cannabis cultivation was found at West Cairns.
The court heard evidence that animosity between Smith and the deceased was fuelled by the fact Smith's wife had helped the authorities convict Mr Cameron of drugs offences by keeping a log of vehicles and visitors to the farm.
During his evidence, Smith broke down in court as he talked about having to have his pet donkey put down three day after he killed Mr Cameron.
When defence counsel Murray Macara put to him: "It might seem you're a bit more upset by the donkey than about Mr. Cameron",  Smith replied: "I loved that wee donkey."
Following the hearing, Mr Cameron's family issued a statement thanking the jury for their time and deliberations in coming to "the true and lawful verdict".
Spokesman Ronnie Mill said: "Alex was a much-loved father, grandfather, brother, family member and friend to many. He is, and always will be, sorely missed by all who knew him.
"James Smith is a coward and a callous, evil, cunning and manipulative person who showed more compassion during evidence for a farmyard animal than he did for a human being.
"He struck a pensioner about the head and body with blunt instruments, bound his hands and feet and buried him in a shallow grave.
"He then tried to avoid detection by trying to remove DNA traces from the weapons he used and by phoning Alex after he had killed him to create an impression that he was concerned about his whereabouts."
Det Insp Stuart Wilson, of Police Scotland, said: "Alex Cameron was subjected to a violent assault on West Cairns Farm and sustained a number of serious injuries, which ultimately resulted in his death.
"James Smith then went to extraordinary lengths to conceal his victim's body before eventually confessing to his crime.
"As a result of today's conviction, Smith will now spend a considerable period of time in prison and I hope that the family of Alex Cameron can now begin to put their ordeal behind them."


Next year's assembly election will be a "straight fight" between Labour and Plaid Cymru, according to Leanne Wood.

But the Plaid leader refused to be drawn on whether she would work with Labour in coalition.
The two parties ran a government together in Cardiff Bay between 2007 and 2011.
At the general election, Plaid said it wanted to work with a UK Labour government to keep David Cameron out of Downing Street.
But looking to ahead to next May's assembly election, Ms Wood said: "It's a straight fight in many people's minds between Plaid Cymru and Labour.
"People need to ask themselves who is going to be the next first minister of Wales and they have got a choice between the existing first minister or myself as the first minister candidate for Plaid Cymru - it's as simple as that really."
Her party will go into the election as the third largest in the assembly behind Labour and the Conservatives.
But speaking to BBC Wales' Sunday Politics programme, she said the Tories - who she has ruled out working with - were "not relevant" in the assembly.
A Conservative party spokesman responded by saying Leanne Wood was the only person in Wales who believed this, adding: "In reality, most voters know that a vote for Plaid Cymru is a vote for Labour."
He added that "despite general election coverage beyond their wildest dreams", Plaid had failed to make an impression outside the seats they already held.
"Voters seeking respite from 17 painful years of Labour dominance will be looking to Andrew RT Davies and the Welsh Conservatives to deliver a new Wales, and we will be taking that positive message to the doorsteps between now and May 2016," he said.
Plaid failed to add to its tally of three parliamentary seats at the general election.
The party's campaign was criticised by one of its most prominent AMs, former Plaid leader Lord Dafydd Elis-Thomas.
His comments have angered some in the party and Ms Wood confirmed Plaid's national executive is talking to his local party about whether to take action against him.
Asked whether that could mean he does not stand again for Plaid in the Dwyfor Meirionnydd constituency, she said she was "not at liberty" to talk about what the outcome could be.


The Conservatives have won the most seats in the Cornwall Council elections.

The Tories have 46 out of the 122 seats being contested with the Liberal Democrats as their nearest rivals with 37 seats, followed by 30 Independent councillors.
Labour have five seats and Mebyon Kernow four.
The unitary authority's remaining 123rd seat, Bodmin St Petroc, will be contested at a later date.
It was delayed following the death of Liberal Democrat councillor Steve Rogerson.
Election 2017: Full results from across England
Local election reaction from Devon and Cornwall
The Tories are the largest group with 46 seats but they would need need 62 seats to have overall control of Cornwall Council.
They could form a minority administration or there could be deals to be done.
Over the weekend there will be talks going on between all the main parties to decide who is going to be in charge for the next four years.
The council has been led by a coalition of Liberal Democrats and Independents since 2013.
In that election the Liberal Democrats took 36 seats, the Independents took 35, the Conservatives had 31, Labour had eight, UKIP had six, Mebyon Kernow had four, the Greens had one and candidates declared as "unspecified" took two.


The Queen will mark the 175th anniversary of the first train journey made by a British monarch.

On 13 June 1842, Queen Victoria made the trip from Slough to Paddington, writing in her journal afterwards that it was "delightful and so quick".
The Queen and the Duke of Edinburgh will embark on the same journey on the day of the anniversary.
Joining them will be two descendants of pioneering railway engineers Isambard Kingdom Brunel and Sir Daniel Gooch.
Mark Hopwood, managing director of Great Western Railway, said he was delighted the Queen was marking "this historic anniversary".
"This occasion marks a very special moment in the history of the Great Western Railway," he said.


Derry and Fermanagh both salvaged late draws to boost their hopes of avoiding relegation from Division Two.

Cavan enhanced their promotion prospects with a comfortable 1-17 to 0-15 home win over Laois and will go up to Division One if they beat Galway next Sunday.
An injury-time free from Ryan Bell gave Derry a 2-12 to 2-12 draw with Meath.
Declan McCusker rescued a valuable point for 14-man Fermanagh who drew 0-15 apiece with Galway in Tuam.
Pete McGrath's side host Tyrone in next Sunday's final round of fixtures still needing something from the game, with the games between Armagh v Derry and Laois v Meath also crucial in determining who falls through the trap door into Division Three.

Derry had a terrific battle with Meath at Owenbeg, Mickey Newman's 10th minute goal giving the Royals an early advantage but Derry hit back with a Danny Heavron goal on the half hour mark.
Cillian O'Sullivan gave Meath a second major of the half and they led 2-4 to 1-6 at the break.
Niall Loughlin's 41st minute goal put Derry back in front and Damian Barton's side hit four points in a row with Christopher Bradley and Benny Heron among the scorers.
They led by 2-11 to 2-7 with 10 minutes remaining before Meath rallied with five unanswered points.
Andrew Tormey thought he'd hit the winner for the visitors before Bell eased Derry's nerves a crucial injury-time free to draw the game.
There was also a dramatic finish for Fermanagh, who hit the last two scores through Tomas Corrigan (free) and McCusker to rescue a valuable league point in Tuam.
Promotion hopefuls Galway led 0-7 to 0-6 at half time and Fermanagh's challenge looked doomed when Niall Cassidy received a red card in the 41st minute.
Galway still led by two points as the game entered stoppage time with Fermanagh's late heroics leaving them on five points, one ahead of Armagh and Meath and two ahead of Laois.
The draw didn't dent Galway's promotion chances as they still face a winner-takes-all promotion shoot-out with Cavan at Breffni Park on 3 April.
Seanie Johnston's 14th minute goal helped Cavan lead by 1-9 to 0-8 at half time against Laois and they led from start to finish for a comfortable five-point win.
Gearoid McKiernan kicked 0-3 from play with Johnston top-scoring with 1-3.

Adam Gemili produced a champion's display under immense pressure to take the British 200m title and win his place in the GB Olympic squad.

Media playback is not supported on this device
The reigning European champion held off Danny Talbot and Zharnel Hughes on a track where he ruptured his hamstring a year ago.
British record holder Dina Asher-Smith edged out Desiree Henry and Jodie Williams in the women's event.
Matthew Hudson-Smith won the 400m in a European leading time of 44.88 seconds.
On his home track, Hudson-Smith pulled away from Rabah Yousif and Martyn Rooney and held his form down the home straight as Yousif came through in second with a characteristic late surge.
In the absence of established stars such as Mo Farah, Greg Rutherford and Jessica Ennis-Hill, Andy Pozzi produced one of the other performances of the weekend to win the 110m hurdles with a personal best of 13.31 secs into a headwind of 1.3 metres.
Pozzi, taking part in his first British championships since 2012 after four years of injury, sealed automatic Olympic selection, along with Lawrence Clarke, who was second.
Gemili had never before won a national title but he powered past Hughes in the lane outside him on the bend and then kept his form as Talbot closed in the last 20 metres to win in 20.44 secs.
A seemingly-unfit Hughes could only come fourth in 20.84, meaning he faces a shoot-out with Nethaneel Mitchell-Blake for the third and final Olympic 200m place.
Gemili, who missed the British Championships last year through injury, said: "This time last year, I was watching on TV as my hamstring was in two pieces.
"That third spot will be tough. Rather them than me. I am glad I booked my place, I wanted to do that automatically. If I didn't then it would have been a tough selection for everyone.
"I know those guys aren't 100%, but when they are they can fly."
Asher-Smith was given a scare by Henry, looking to put the disappointment of her 100m display on Saturday behind her, her margin of victory - 23.11 secs to 23.13 secs, with Williams a further nine-hundredths of a second back - testament to the depth of talent Britain has in the women's sprints.
Athletes needed to finish in the top two in their event this weekend and have two performances inside the qualification standard to be guaranteed a place in the squad for Rio.
While that was straightforward for some - Eilidh Doyle dominating her 400m hurdles final in 54.93 secs, Charlie Grice and Chris O'Hare taking an expected one-two in the 1500m - it left others with anxious weeks ahead.
The final deadline for qualification times is 11 July and Sebastian Rodger will be one hopeful chasing another quick time after winning the men's 400m hurdles but with only one mark under his belt.
But Jack Green, who has battled depression and came off his medication in order to get in the optimum physical shape, will be on the plane for Rio after coming in second with the requisite times already under his belt.
There was emotion too for Steph Twell after she won her third 5,000m title to qualify for her second Olympics, having missed out on London after an awful ankle injury, and for Eilish McColgan, who will join her after fighting through for second.

Laura Muir and Laura Weightman both qualified from the 1500m, the former with an impressive front run, while Jazmine Sawyer produced a brilliant personal best of 6.75m in the penultimate round of the long jump to steal both the title and a debut Olympics spot.
Yet there was disappointment for Goldie Sayers, 11 times the British javelin champion, as she was beaten into second place by a personal best of 57.44m from Jo Blair. She will now need to find a throw of 62 metres or more before that July deadline if she is to go to her fourth Olympics.
Lynsey Sharp has the consolation of an Olympic place to make up for her 800m defeat by 2015 world finalist Shelayna Oskan-Clarke, but seven-time champion Michael Rimmer suffered a huge upset when beaten by Elliot Giles and Jamie Webb, and will now have to hope for the selectors' largesse.

A £400m project to transform a shopping complex in Oxford city centre has been unveiled to the public.

Plans for the Westgate Centre include 70 new shops, a roof-top terrace with views over the city and a basement car park with more than 1,000 spaces.
The Westgate Alliance believes 3,000 jobs could be created. It is submitting a planning application to Oxford City Council in the summer.
An Oxfordshire Green Party spokesman called the plans "excessive".
He added: "We want this council-owned site to include more affordable housing than the current plans.
"Few cities are building this type of shopping mall due to changes in shopping habits. We think it could end up a white elephant and/or impact on other retail offerings within the city.
"Oxford's independent traders would be the worst hit."
But the owners have said the new complex will be "one of the leading shopping and entertainment destinations in the UK".
Sara Fuge, development manager, said: 'We want to create an exciting new destination in the heart of Oxford that will attract visitors from across the city and beyond."
And Bob Price, leader of the city council, said: "This is an incredibly exciting project that will transform the retail and leisure experience in Oxford."
The new development will retain the current library and add a 10,000 sq m (32,808 sq ft) John Lewis department store.
About 30 new homes, as well as cafes, restaurants, covered streets, public squares and a cinema have also been proposed.
The current building was constructed in the 1970s. Westgate Alliance wants the new complex to be completed by 2017.
A public exhibition of the proposal is running at the centre until 28 June.
Ian Hudspeth, leader of Oxfordshire County Council, said: "This is a fantastic opportunity to share these proposals with the local community and we hope to get as much feedback as possible."


Tottenham Hotspur have had revised plans for a new stadium approved by Haringey Council.

Spurs hope to move to their new 61,000-seat home for the 2018-19 season.
The planning proposal featured aspects tied in to a deal that will see at least two NFL matches at the stadium each season in a 10-year period.
The plans must be formally approved by the London Mayor and the current incumbent in that position, Boris Johnson, is a fan of the project.
"Stadium Update: We can announce that Haringey Council's planning sub committee has approved the club's new stadium proposals," the Premier League club tweeted.
The stadium will be built as part of a development that would also include the land their current White Hart Lane ground, which has a capacity of 36,240, stands on, with work due to begin in spring 2016.
"A key driver of the design of the revised scheme has been to address and improve crowd safety and crowd flow issues along the High Road," a recent Spurs statement explained.
"This issue has long been a concern for the club and is largely caused by the location of three buildings on the High Road: Edmonton Dispensary, The Red House, and the former White Hart Public House.
"The current planning permission does allow for increased space behind the three buildings but the crowd flow modelling shows that spectators would be much more likely to continue to take the most direct route along the High Road, with people regularly moving into the bus lane and the road.
"Given the increased number of spectators, not simply for football but for the NFL and other visitor attractions, this is simply not a situation the club can accept."
Tottenham intend to play away from their home ground for the 2017-18 season "to enable a faster construction of the new stadium" before opening it in time for the 2018-19 campaign.


Fetch, sit and roll over - all the kinds of normal things that you would say to your dog.

Ricky has been finding out about one dog who was having some language issues.


Avid Life Media, the owner of infidelity dating website Ashley Madison, is being investigated by the US Federal Trade Commission (FTC), company executives said.

Last year, hackers stole the personal information of millions of the website's customers, which helps link up married people who wish to cheat.
The hack led to an internal shake-up.
Chief executive Rob Segal and president James Millership took the helm in April, Avid Life said on Monday.
The two told Reuters they did not know the exact focus of the FTC's investigation.
A spokesperson for the commission declined to comment on the investigation.
The FTC's consumer protection unit can investigate cases where consumers were told their information was secure, but was then handled recklessly or inappropriately.
In 2015, hackers published the data stolen from Ashley Madison, exposing the personal information, including names, of the website's users.
Ashley Madison- which uses the slogan "Life is short, have an affair" - has faced a mounting list of investigations and lawsuits since the website was hacked.
In a statement on Monday, Mr Segal said: "The company is truly sorry for how people's lives and relationships may have been affected by the criminal theft of personal information."
The company plans to spend millions of dollars improving its cyber security and Mr Millership said its aim was "to rebuild Ashley Madison as the world's most open-minded dating community."
In 2014, another of Avid's dating sites, JDI Dating, paid $616,165 (Â£473,268) to settle an FTC investigation into that site's use of computer programs that created fake profiles, known as fembots. The use of fembots was judged to be misleading to customers.
Ashley Madison was also exposed for using fembots in 2015. The website used these programs to strike up conversatiosn with paying male customers. The website has a five to one male to female ratio.
Avid said it shut down these fake profiles in the US, Canada and Australia in 2014 and the rest of the world by 2015.


The US has said it will limit arms sales to Saudi Arabia amid concerns over civilian casualties linked to air strikes in Yemen.

Precision-guided weapons will no longer be delivered, a Pentagon official said.
President Barack Obama's administration said it was concerned over "flaws" in the way air strikes are targeted in Yemen.
In October, more than 140 people were killed in a strike on a funeral in the country.
A Saudi-led coalition, which is attempting to support the elected government against Iranian-backed Houthi rebels, was blamed for the attack.
White House National Security Council spokesman Ned Price later warned Saudi Arabia that US security co-operation was "not a blank cheque".

But while some sales are being scaled back, the US said it will continue to provide Saudi Arabia with intelligence focused on border security.
It will also provide training for pilots involved in the Saudi-led air campaign, to avoid civilian casualties wherever possible, the official said.
Other contracts are expected to go ahead such as a deal worth more than $3bn (Â£2.4bn) to supply military helicopters.
The Saudi-led coalition is fighting the Houthi rebel movement in Yemen.
Thousands of civilians have been killed and nearly three million people have been displaced in the country, one of the region's poorest, since the war began in 2014.
The Houthis took the capital Sanaa, forcing Abdrabbuh Mansour Hadi's government to flee. Some ministers have since returned to the city of Aden.
Saudi Arabia has denied causing large-scale civilian deaths, saying it is making every effort to avoid hitting civilian targets.


A Milton Keynes artist who claims to have hidden a cheque for £8,000 in an art gallery has urged the public to "take care" while searching for it.

Tomas Georgeson hid the incomplete cheque in the Milton Keynes Gallery to help promote the town as a "cultural destination".
He said whoever discovers it can write the cheque out to themselves.
Gallery director Anthony Spira, said staff "knew nothing about it" but would "scour" the building looking for it.
Primarily a painter, Tomas Georgeson was the winner of the Derby Open competition in 2002 and exhibited his Portrait of my Father at the National Portrait Gallery as part of the 2011 BP Portrait Award.
Mr Georgeson said he had "the greatest respect" for the gallery, its director and its exhibitions programme.
He said: "I should point out that I have not hidden the cheque on or around any of the artwork on display and the public should take proper care if they choose to look for the cheque.
"I hope that the personal risk I have taken in doing this can stand as something positive in a town eager to establish itself as a cultural destination.
"Milton Keynes began with a sense of bold, risk taking creativity and long may that continue."
Mr Spira said the claim had come as a "complete surprise" and he had brought in extra staff to guard its displays.
He revealed there had "definitely been more visitors than normal" on Wednesday after the story appeared in the Daily Telegraph.
He said: "It's early days, they haven't been queuing around the block but there have been about 30 extra people in the first two hours and some have not been to the gallery before so that is fantastic.
"So far so good, nothing has been destroyed but we have had people rifling through our bookcases, looking for clever titles which might be hiding it."
If unclaimed, the cheque will be collected on 1 March.


A police officer in Inverness has been photographed carrying a firearm despite assurances that sidearms would only be deployed under special circumstances.

The officer was carrying a handgun in the railway station in Inverness on Tuesday as he walked through the main concourse.
Police Scotland said the officer had breached new force policy.
A spokesman said he had been reminded of the strict criteria about the issue.
It was a sight more common in 2013 when a policy was introduced allowing firearms officers to carry handguns with them at all times while on duty.
However, after concerns from politicians, the chief constable of Police Scotland, Sir Stephen House, stated last October that specialist armed police officers in Scotland would only be deployed to firearms incidents or where there was a threat to life.

Mae cwmni oedd yn rhedeg cynllun bwyta'n iach i blant, gafodd ei ddatblygu gan Brifysgol Bangor, ar fin cael ei ddiddymu gyda dyledion o dros £1.2m.

Bwriad Food Dudes oedd annog plant i fwyta'n iach gan ddefnyddio DVD a chymeriadau cartŵn arwrol oedd yn derbyn grymoedd hud drwy fwyta'n iach.
Roedd y cynllun yn ganlyniad i 25 mlynedd o ymchwil gan seicolegwyr ym Mhrifysgol Bangor.
Yn ôl y trefnwyr, mae wedi helpu 700,000 o blant ar draws y DU, Ewrop a'r UDA i fwyta'n fwy iach ers iddo gael ei sefydlu ddechrau'r ganrif hon. Yn Iwerddon cafodd y cynllun ei gyflwyno i bob ysgol gynradd.
Mae BBC Cymru wedi gofyn i Brifysgol Bangor am ymateb.
Mae gwefan y cynllun yn dweud ei fod wedi derbyn arian gan "nifer o ffynonellau yn cynnwys cynghorau ymchwil, y diwydiant bwyd, tyfwyr ffrwythau a llysiau, consortia archfarchnadoedd, iechyd cyhoeddus y DU, yr UE a Phrifysgol Bangor."
Yn 2012 cafodd y gwaith o redeg y cwmni ei drosglwyddo i gwmni o'r enw Food Dudes Health Limited. Tri academydd o Brifysgol Bangor oedd ar fwrdd y cwmni.
Aeth y cwmni hwnnw i'r wal ac fe ddechreuodd y broses o'i ddiddymu yn 2015, ac mae disgwyl i'r broses honno gael ei gwblhau yn y misoedd nesaf.
Ymysg rhestr credydwyr y cwmni mae cyrff iechyd cyhoeddus a chynghorau yn Lloegr, sydd gyda £800,000 yn ddyledus iddyn nhw, ac mae £200,000 yn ddyledus i Brifysgol Bangor.
Dywedodd diddymwr y cwmni, Ian Brown o Parkin S Booth & Co yn Lerpwl: "Dechreuodd y broses o ddiddymu Food Dudes Health Ltd ar 9 Hydref 2015 ac fe ges i fy newis i'w ddiddymu.
"Ar 17 Mawrth 2016 cafodd hawliau eiddo deallusol y cwmni eu gwerthu i Brifysgol Bangor am £20,000.
"Roedd rhan o'r gwerthiant yn cynnwys hawliau ar gyfer yr enw 'Food Dudes Health' ac yna cafodd y newid enw i Grub Men Ltd ei gofnodi ar 3 Mai 2016.
"Mae'r broses ddiddymu'n dirwyn i ben ond hyd yn hyn nid yw'r adroddiad terfynol wedi ei roi i'r credydwyr. Byddwn yn disgwyl i hyn ddigwydd o fewn y tri mis nesaf."


New Formula 1 boss Chase Carey says there will be a British Grand Prix despite speculation Silverstone could be dropped by 2019.

The circuit's presence on the calendar had been under threat because of the "potentially ruinous risk" of staging the loss-making race.
However, Carey - who has been put in charge of F1 by new owners Liberty Media - says its future is safe.
"We will have a British Grand Prix," he told BBC Sport.
"The foundation of the sport is western Europe. We want to grow it. There's a negotiating dynamic that exists, but we want a healthy relationship with our promoters.
"We are going to look at ways of making events bigger and better."
Carey has taken over as F1's chief executive from Bernie Ecclestone following US giant Liberty Media's $8bn (£6.4bn) takeover.
Ross Brawn has been appointed managing director as part of a restructuring of F1's management.
And the former Mercedes boss said Silverstone is "very important" to the tradition of the sport.
"A lot of the new circuits are very exciting and they bring their own element to F1," he said.
"They are in it because they want to be part of that show that includes Monaco, Silverstone, Monza, Hockenheimring and the Nurburgring.
"You have still got to maintain those traditions to have the values in F1."
Silverstone first hosted the British Grand Prix in 1950 and has been the event's permanent home since 1987.

A factory worker has been convicted of the "sickening murder" of his former partner who was six months pregnant.

Mother-of-two Isobel Parker, 23, who was known as Becky, was found dead in the bath in her flat in Burnham-on-Crouch, Essex, last July.
Matthew Smith, 24, had admitted killing Ms Parker but denied murder.
A jury at Chelmsford Crown Court found Smith, of Wood Corner Caravan Park, Maldon, guilty by a majority verdict following a three-week trial.
Follow updates on this story and other Essex news
Judge Charles Gratwicke said Smith could expect a substantial sentence when he returns to court on Tuesday.
Det Ch Insp Martin Pasmore said Smith "could not accept his relationship with Isobel was over after she had moved on to the extent that she was six months pregnant by a new partner".
"The jury has today seen through his lies and convicted him of murder."
Ms Parker's body was found by her sister in the property in Booth Place on 17 July 2015.
During the trial, the court heard she had been strangled to death with cable ties.
Ms Parker ended her relationship with Smith in December 2014. He had not taken the split well and had tried to kill himself, the jury was told.
The court also heard Smith was "unhappy" and "very jealous" that she was pregnant by her new boyfriend.


Emergency crews were called to tackle a blaze at one of their own fire stations.

Fire broke out in the drying room at Alresford Fire Station - a retained station - on Sunday morning.
It is thought the fire was caused by a fault with the drying cupboard heater on the ground floor.
No one was injured, but the building, which is also used by Hampshire Constabulary, was left without power.
More on this and other stories from across the South of England
Crews from Winchester, Hightown and Alton were called out at about 10:30.
Hampshire Fire and Rescue said the ground floor was "severely smoke logged", but there was no serious damage and there was no one inside at the time.
Back-up generators have been brought in to enable police and fire crews to continue working as normal.


Manager Chris Coleman says he is focused purely on rejuvenating Wales' hopes and not his long-term future.

Media playback is not supported on this device
Coleman, 46, has a contract until after the 2018 World Cup but has been linked with the vacancy at Crystal Palace as well as hinting he could walk away if Wales lose ground in qualification.
"I said if it comes to a point and we cannot affect our future, I need to sit down with the powers that be," he said.
Wales are third in qualifying group D, four points behind leaders Serbia.
Wales will travel to Serbia for their next qualifier on 11 June after naming a youthful pre-match training camp that included Exeter's 16-year old Ethan Ampadu.
However, Coleman has distanced himself from speculation linking him with his former club Crystal Palace, who are seeking a successor to Sam Allardyce.
Allardyce has resigned as the Selhurst Park club's manager, five months after he joined the Premier League club.
"I would love to go back to the Palace - I am not sure Prince Charles is just ready for me yet," joked Coleman, who recently received an OBE at Buckingham Palace.
"All I care about now is Wales. I don't think about after Serbia.  I cannot afford to think past one game.
"Lots of things have been said on the back of comments I said at the start of the campaign [about leaving if Wales were not competitive] when I signed a new contract. That hasn't happened yet.
"But honestly I cannot go into a game of football thinking 'if we lose' because then I will have lost, we will have lost and I have never thought like that.
"When it comes that we cannot [qualify] - if it comes that we cannot - then there is a conversation to be had.
"But I think we will [qualify]. I am confident we will. I know it's a huge task for us. I still have the same excitement to do the job. I still have the same belief in the players and the team."
Coleman has named a 26-man squad for a training camp at the Vale do Lobo resort in Portugal before the qualifier in Belgrade which follows four successive draws in Group D.
The squad, which is without the suspended Gareth Bale and Neil Taylor, will be reduced to 23 for the trip to Belgrade.
"We are four points behind going to Serbia and we haven't got our best player, what can happen here?" Coleman added.
"I will tell you what can happen. We can go there and get a result that is what can happen.
"And then in the four games remaining we need to be looking at maximum points. We did that in the last campaign so why can't we do it again?
"This is one of the toughest groups but I think we are one of the best teams.
"I don't believe we are far off at all. And I will not start to think if this happens and it's a negative and my future.
"My future is Serbia, Belgrade that is what my future is. Can we produce and can we perform?"
When Wales travel to Serbia, they will be returning to the country where Coleman suffered the lowest point of his managerial career - a 6-1 thrashing in 2012.
That is another reason why the former Wales centre-back does not want to leave his role now.
"It wouldn't look very good now if I did jump ship before we go back to Serbia," he added.
"It would look cowardly as well, going back to Serbia where I got my backside spanked.
"It is a game I am really looking forward to. I don't know what is going to happen but I am used to the speculation.
"I am not ready to say to the FAW and Wales and to my players and to ring them up and say thanks for that. I don't think my journey is finished yet. I am not ready to hand this over to someone else, not yet I am not.
"So I am not thinking about anything else other than Serbia that is for sure."


Harlequins held on after a second-half comeback from Sale to register their seventh Premiership win of the season.

Tim Swiel and Will Addison traded two early penalties each before Denny Solomona gave the visitors the lead.
Charlie Walker's try levelled before Swiel's length-of-the-field score.
Byron McGuigan's try got Sale back into it after a third Swiel penalty after the break, but two more Swiel penalties sealed the win despite Solomona's late second try - his fourth in three games.
Seventh-placed Quins moved level on points with Leicester, although the Tigers have a game in hand, while Sale are now six clear of 11th-placed Worcester thanks to their losing bonus point.
Quins were forced into a late change for England prop Joe Marler and could have gone behind when Solomona, playing just his third Premiership game since his controversial move from rugby league side Castleford, had a try chalked off for a forward pass after a video referral.
But he did not have to wait long before going over as he pounced up a loose ball, but Quins hit back with Walker going in under the posts after great play from James Chisholm and Mike Brown before Swiel raced half the length of the field to increase Quins' lead after a spilt kick just before the break.
McGuigan's try got Sale within two points, but Addison missed the conversion which would have levelled it as Sale's indiscipline was punished by Swiel before Solomona pounced on a clever kick from TJ Ioane to seal a bonus point and a nervous finish.
Harlequins director of rugby John Kingston:
"The win was a massive positive as we dealt with every challenge with unbelievable tenacity, which shows the togetherness of the team.
"Will Collier has broken his ankle and Nick Evans was very frustrated at not being able to return, having failed to pass a head injury assessment.
"Joe (Marler) had a problem with a stamp that he picked up against Gloucester and he had another knock on it at Worcester last week.
"He didn't train with England in the week but we did a bit yesterday and he began to feel it in the warm-up.
"We left it up to him and we erred on the side of caution. It's a strain and he will have a scan but I don't see a problem with him being available for the Six Nations, at this stage."
Sale head coach Steve Diamond:
"I'm satisfied with the bonus point as I've come down here before and lost by 50 points.
"Our performances in the past two weeks have been much better and if we play like that, we won't lose another game at home this season.
"We need to get security in this competition ahead of recruitment for next season but we need to have a bit more control and get the ball to Denny, who certainly knows where the whitewash is."
Harlequins: Brown; Yarde, Alofa, Marchant, Walker; Evans, Care (capt), Marler, Buchanan, Collier, Merrick, Matthews, Wallace, Ward, Chisholm.
Replacements: Gray, Evans, Sinckler, South, Naoupu, Dickson, Swiel, Hopper.
Sale: Haley; McGuigan, Addison, Leota, Solomona; James, Mitchell; Harrison, Webber, Aulika, Evans, Ostrikov, Neild, Ioane, Beaumont (capt).
Replacements: Briggs, Flynn, Longbottom, Mills, B Curry, Ioane, Phillips, MacGinty, Charnley.

Ambulance trusts spent hundreds of hours having to appeal against speeding fines issued to emergency vehicles by police forces.

More than 20,000 tickets were issued to paramedics after they were caught on speed cameras responding to 999 calls.
Only 400 of those tickets were upheld, a Freedom of Information request by the BBC has found.
The police said some speed cameras only captured the speed and number plate of the vehicle.
Health bosses have called for the automatic exemption on emergency vehicles to be better enforced. Some trust staff are spending 40 hours a month appealing against the fines.
A Freedom of Information request by the BBC to all ambulance trusts in England showed they received 23,227 speeding tickets between 2009 and 2014.
If not appealed against, some trusts would be facing a bill of up to £160,000 a year.
Yorkshire Ambulance Service Trust had to appeal against fines that would amount to more than £774,000 over five years, while the South Central Ambulance Service Trust, covering Berkshire, Buckinghamshire, Hampshire and Oxfordshire, spent up to 10 hours a week appealing against the fines.
The highest speed recorded was 115mph in a 50mph zone by the South Western Ambulance Service.
Appeal process:
Carl Rees, from the Association of Ambulance Chief Executives, said "common sense should be applied" and "notices should only be sent out if no blue lights can be seen flashing".
"After the appropriate checks have been made the PCN (penalty charge notice) should be waived. We understand that this is what happens in the majority of cases," he said.
The law:
Section 87 of the Road Traffic Regulation Act 1984 states:
Source: "Guidance regarding the legal obligations placed on forces as body corporate when dealing with speeding and red light offences by emergency service vehicles"
Association of Chief Police Officers of England, Wales and Northern Ireland
Assistant Chief Constable Stephen Barry, from the National Police Chiefs' Council, said while police would generally stop notices from being sent out, this was more difficult since the introduction of average speed checks.
"When an emergency vehicle clearly displaying blue lights triggers a camera, but the police can see that it was being driven safely in accordance with the law with blue lights displayed, they would generally stop notices from being sent out.
"This has been made more difficult with the introduction of average speed checks in recent years, which usually capture the speed and number plate of the vehicle but not necessarily an image."


About £50,000 worth of artwork by Belfast artist Terry Bradley has been stolen after a "well-planned" raid.

It is estimated that between 80 and 100 pieces of art were taken from a pop-up gallery in the city centre.
These included original canvases worth up to £10,000. A large original painting of Batman, worth an estimated £2,500, was also taken in the burglary.
Ashley Bradley, the artist's wife, said they believed thieves gained access after one hid in the gallery overnight.
She added that Mr Bradley was "devastated" by the thefts.
"Terry puts his heart and soul into his work," she said. "They're a moment in time. The original pieces cannot be replaced.
"Some of the original drawings have been ordered by people for Christmas - they're all gone. So much stuff has been paid off by customers and we're going to work to replace what we can.
"Terry is completely floored by what's happened."
Staff at the gallery have said they will work hard to replace the stolen artworks. Gayle Williamson said she was heartbroken when she arrived at work this morning: "I was speechless. What can you say?
"It's horrendous and I wasn't expecting it in the mouth of Christmas, but we'll do our best to replace what orders we have."
Police said they are appealing for witnesses to the burglary that took place on Chichester Street between 18:00 GMT on Wednesday and 10:00 on Thursday.
Mrs Bradley said the family believed the gallery had been targeted by people who "knew what they were doing".
"We think someone had hidden in the gallery and opened the back door," she said.
"I was in last night with my daughter at about 21:30. We hope somebody wasn't in there with us.
"It would have taken a long time. These are big and heavy pieces - I can only lift one picture at a time.
"My sister opened at 10 o'clock this morning and it was all gone."
Mrs Bradley, who vowed that the gallery would re-open on Friday, urged anyone who has any information to come forward.
"We're going straight back to work. Nobody was hurt. Hopefully we have enough time before Christmas to replace what can be replaced.
"My hope is a fan of Terry will see this art being passed off. I know they'll be outraged when they hear this has happened.
"If someone sees them, they will know what they are and hopefully come forward with information so we can get them back."
Stolen artwork by Mr Bradley has been recovered before.
In 2014, two paintings, worth £6,000 each, were taken from a shop in south Belfast. Police found them after a tip-off.
