Detectives leading a criminal investigation into the Hillsborough disaster have released CCTV images of 19 men they want to speak to.

Ninety-six fans were killed as a result of the crush at the football ground in Sheffield in April 1989.
Images of potential witnesses at the stadium's Leppings Lane end have been released as part of Operation Resolve.
Senior investigating officer Neil Malkin stressed the men pictured "had done nothing wrong".
Det Ch Supt Malkin said the men seen near Exit Gate C when it opened at about 14:50 were in the "right place at the right time" and may be able to identify others.
"Together with evidence already gathered, it would mean we can provide a complete picture of events to the Crown Prosecution Service," he said.
"We just want to focus on them to try and conclude what happened. The potential evidence could help shape our understanding of what happened at Gate C."
In April an inquest jury concluded the 96 who died at Hillsborough were unlawfully killed.
It found a number of errors by South Yorkshire Police and South Yorkshire Ambulance Service, as well as stadium defects, contributed to the deaths.
Hillsborough inquests: The 96 who died
Operation Resolve is one of two criminal investigations ordered following the publication of the Hillsborough Independent Panel's report in 2012.
A separate criminal investigation by the Independent Police Complaints Commission is examining police conduct.
Some relatives of those who died have expressed concerns over the new appeal for witnesses near Gate C.
Lou Brookes, who lost her brother Andrew at Hillsborough, told the Victoria Derbyshire programme earlier she was "absolutely disgusted".
She said: "I have serious concerns for their motives and objectives for pursuing this issue."
Lawyer Elkan Abrahamson, who is representing a number of Hillsborough families, said: "Operation Resolve in the course of the inquest came up with an absurd theory that Gate C was opened before [police match commander] David Duckenfield gave the order to open it.
"When we corrected this they then abandoned that theory and they seemed then to be pursuing another theory that even if it was opened after the order was given, it wasn't opened because of the order."
"If that is the theory that they are still pursuing I just can't see the point in it."
An Operation Resolve spokesperson said comments made by some families had been raised and considered."
They added: "Our job is to conduct a thorough and impartial investigation particularly around the opening of gate C.
"We are keen to identify and interview the 19 people in our witness appeal as we believe that they could hold vital information."
Operation Resolve has taken more than 1,200 statements from fans who approached from the Leppings Lane end on the day of the disaster.
A video reconstruction of the ground as it was in 1989 has been created to help jog people's memories.
Det Ch Supt Malkin said: "We are hoping with the context people will recognise themselves or friends and family. These people may recognise each other.
"We want to hear their experience of entering through Gate C, how they came to be there at that time, what they saw, what they heard."
The detective urged people to come forward and to inform police if any of the 19 have since died so they can be eliminated from the investigation.
A file is expected to be passed to the Crown Prosecution Service at the end of the year.


A Panamanian fisherman who survived 28 days adrift in the Pacific and watched two companions die is suing the owners of a cruise ship that sailed past.

Adrian Vasquez has filed a lawsuit in Florida alleging negligence by Princess Cruises, his lawyer said.
The American cruise company has said it deeply regrets that one of its ships sailed past the dying men.
Passengers said they spotted the castaways and alerted staff, but the firm said the captain was not informed.
Mr Vasquez's lawyer, Edna Ramos, said the lawsuit includes testimony from two cruise ship passengers who said they saw the boat and reported it to a member of staff.
One passenger, Judy Meredith, earlier told reporters she had informed a sales representative about the boat and had shown him it through a spotting telescope.

She said she had been assured the information had been passed on to the crew.
Mr Vasquez and his friends set out in their three-metre-long open fishing boat the Fifty Cents from the port of Rio Hato in February, and were on their way back after their catch when the engine failed.
After 16 days adrift, he says, they saw a cruise ship sailing past, and had made attempts to flag it down with a red sweater.
"We felt happy, because we thought they were coming to rescue us," he said.
Mr Vasquez was eventually rescued 1,000km (620 miles) off the mainland, near the Galapagos Islands. His friends had already died of thirst.
He said he survived thanks to a sudden rainstorm that replenished his drinking water supplies.
Princess Cruises said there appeared to have been a "breakdown in communication".
It said the captain - Edward Perrin - and the officer of the watch were not notified.
Princess Cruises said it understood its responsibility under the law of the sea to help any vessel in distress, and said its ships had been involved in more than 30 rescues over the past decade.


Struggling League One club Chesterfield are to be put up for sale by their majority shareholder Dave Allen.

Club director and company secretary Ashley Carson revealed the news at Monday's annual general meeting.
It comes in the wake of chief executive Chris Turner, 58, taking over last week as the club's director of football.
Chesterfield, who appointed Gary Caldwell as their new manager on 17 January, currently stand second from bottom in League One.
Following Saturday's home defeat by John Sheridan's 10-man Oldham Athletic, the Spireites are three points shy of safety after a run of just one win in eight games, which was at home to bottom club Coventry.
Former Sheffield Wednesday goalkeeper turned manager Turner was appointed as Chesterfield CEO in December 2011.
Allen, who previously had shares in Sheffield Wednesday, first invested in Chesterfield in 2009, taking over as chairman from Barrie Hubbard in 2012 before resigning in November 2016.
He said then that he had put in £1.9m investment over the previous two years, for which Allen, who owns 60 per cent of the club's shares, had not personally charged any interest.


The Conservatives have won the constituency of Gower - a seat Labour has held for more than 100 years.

Following two recounts, AM Byron Davies gained the seat with 15,862 votes - a majority of just 27.
Labour's Liz Evans received 15,835.
Political expert Richard Wyn Jones, from Cardiff University, told BBC Wales it was "a bitter blow" for Labour who had held the constituency for nearly 100 years. The win has taken the tally of Tory-held seats in Wales to 11.
"I'm absolutely delighted that the people of Gower have put their faith in me," Byron Davies said.
Meanwhile, Stephen Kinnock, the son of former Labour leader Neil, has become an MP after Labour held on to Aberavon.
Elsewhere, the party also held Neath, Llanelli and Swansea East.
Conservative Stephen Crabb retained his Preseli Pembrokeshire seat where he has been a MP since 2005.
Labour's Geraint Davies kept Swansea West and Plaid Cymru's Jonathan Edwards held Carmarthen East. Tory Simon Hart held Carmarthen West and South Pembrokeshire.


A US civil rights group has called for more police protection after several mosques in California received letters calling Muslims "vile and filthy".

The Council on American-Islamic Relations (CAIR) said the handwritten and photocopied letters also praised President-elect Donald Trump.
The letters - signed only by "Americans for a Better Way"- warned that Mr Trump would "cleanse America".
There is no indication that Mr Trump is in any way connected to the hate mail.
He has not publicly commented on the issue.
During his electoral campaign, Mr Trump suggested banning Muslims from entering the US.
CAIR said the letters had been sent in recent days to mosques in San Jose, and Long Beach and Claremont in the Los Angeles area.
The letters were addressed to the "children of Satan", the civil rights group said.
A police investigation was under under way into what was treated like a "hate-motivated incident," San Jose Police Department spokesman Sgt Enrique Garcia was quoted as saying by the Associated Press news agency.


A crash with a motorbike which killed Belgian cyclist Antoine Demoitie was an "unfortunate accident", says his team.

The 25-year-old was hit by the motorbike after several riders came down in a crash as the Gent-Wevelgem race passed through northern France.
Jose Been, spokeswoman for the Wanty-Gobert team, told BBC Sport it was "not a case of the motorcyclist going too fast and causing the crash".
Demoitie was taken to hospital in Lille but died some time later.
A French police inquiry is under way and the sport's governing body, the UCI, is co-operating with the investigation.
Demoitie was among several competitors involved in a fall in the one-day race, which was won by world champion Peter Sagan.
"The cyclists fell right in front of the motorcyclist who had no time to react and just hit them," Beem said.
"The motorcyclist is very experienced and has been in the races a long time. He is as grief-stricken as we are.
"It was a very unfortunate, horrible accident for both sides."
At a news conference on Monday, tearful team manager Jean-Francois Bourlart said Demoitie rode his first WorldTour race - the E3 Harelbeke in Belgium - last week.
"He was very proud of himself and we couldn't have been more proud of him," he said.
"On Sunday, the incredible happened, the inconceivable. We can't believe it. We are angry. We cry and we think of his wife Astrid and his family."
Earlier on Monday, Professional Cyclists' Association president Gianni Bugno, a former rider, said: "I do not want to accuse anyone, but make everyone reflect on the responsibility we have to ensure... a very high level of attention, awareness, and control over safety standards during each race."
Several high-profile professional cyclists have paid tribute to Demoitie, while others have questioned whether there needs to be rule changes around motorbikes, which are used mainly for security and media.
In a Facebook post, German sprinter Marcel Kittel said the sport had reached a "new and very sad low point in the history of cycling and safety".


Macauley Bonne's brace gave Leyton Orient a victory at Woking.

The visitors, searching for a swift reprieve after their 6-1 drubbing at Bromley, were almost gifted an early lead when Woking's Josh Staunton headed just past his own net from Joe Ward's tricky ball back to him.
That was as close as either side came before the interval, but Orient got the breakthrough they deserved as Bonne converted Jake Caprice's fine cross after 50 minutes.
The 21-year-old striker, who spent a spell at Woking last season, then got his second of the afternoon with a cool finish late on to wrap up the points for the visitors.

Shares in Royal Mail closed down 8.3% after the firm warned that rivals - including Amazon - were eating into its parcel delivery business.

Royal Mail said the rise of delivery firm Whistl could wipe £200m off sales.
It also said competition was endangering its government-mandated Universal Service, which guarantees a single price postal service that delivers to all UK addresses.
The caution came as Royal Mail reported a small fall in pre-tax profits.
They dropped to £218m for the six months to 28 September, from £233m in the same period last year.
In its financial statement, Royal Mail named Whistl, formerly known as TNT, as a direct threat to future profits.
The company also said it faced increased parcel competition and that Amazon's recently-launched delivery service could singlehandedly dent its business by as much as 2%, in the short term.
In the past six months, Royal Mail's UK parcel delivery division saw revenues fall by 1%.
However the firm's international parcel delivery service, GLS, fared well, with revenue up 7%, helping the company's overall revenue to rise by just £5m to slightly above £4.52bn.
Royal Mail's letter business saw volumes drop by 3%, although this was not as steep a fall as had been expected.
The slower decline was due to election pamphleteering, particularly relating to the Scottish Referendum, for which Royal Mail delivered seven million campaign mailings and over five million poll cards.
Royal Mail boss Moya Greene told the BBC that increased competition was threatening the company's ability to deliver letters to all parts of the UK - a service mandated by law.
She added that the "cherry-picking" of urban mail routes by competitors "undermines the economics" of its nationwide delivery service.
Royal Mail has long called for the regulator, Ofcom, to consider expanding the Universal Service mandate - which ensures mail is delivered across the UK, six days a week, at one fixed price - so that it includes rivals such as Whistl.
That may include forcing competitors to also deliver letters to rural areas at an affordable price - a service for which companies can make little or no profit.
"We believe the current regulatory framework does not fully address the problem posed by unfettered direct delivery competition," Royal Mail said.
"We think there is an urgent need for a new framework that will secure the sustainable provision of the Universal Service for the future."
In response, a spokesman for Ofcom said the regulator's own evidence "clearly shows that the service is not currently under threat".
"We would assess any emerging threat to the service quickly, in the interests of postal users," he added.
Royal Mail has been under increased public scrutiny since it was privatised in October 2013.
In July, a group of MPs voiced concerns that the taxpayer may have lost out by about £1bn after Royal Mail shares were "undervalued".
After an initial pricing of 330p, Royal Mail shares rose above 600p in the months after its flotation, but have been steadily declining since the early summer, to 430p.
Analysis: Kamal Ahmed, BBC Business Editor
Lurking on page 8 of today's numbers is the real story in Royal Mail's results - that the business is warning of a "material risk" to the Universal Service obligation.
Some may dismiss this as special pleading from a company that does not much like competition.
But I have just spoken to the Royal Mail's chief executive, Moya Greene, and she is clear - if action isn't taken now, Royal Mail's ability to fund the six day letter delivery service across the UK will come under possibly unmanageable strain.
"The threat is now," she told me.


"Upside-down rainbows" or "smiles in the sky" have been sighted across Yorkshire.

The optical illusion is not in fact a rainbow according to BBC weather presenter Keeley Donovan,
"It is known as a circumzenithal arc," she said, adding: "It is formed when sunlight is refracted through ice crystals rather than raindrops."
Photographs of the spectrum of colours spotted on Friday have been shared on social media.
One BBC Weather Watcher, Mrs D from Glusburn County Primary School near Keighley, said the children had been delighted to see it.
She said: "My class and all the children saw this circumzenithal arc, which appeared just after the Remembrance service we attended in Sutton Park.
"The children were very excited to see a smile in the sky."
Ms Donovan said the meteorological phenomenon usually forms high up in the sky among the cirrus and cirrostratus clouds.
"Although they form fairly frequently, they are usually obscured by layers of clouds beneath, and rarely visible," she added.


A former coal mine that is now a national museum has taken on two new apprentices to help keep underground memories alive.

It is more than 30 years since the last coal was dug at Big Pit in Torfaen, after which it became the National Coal Museum.
It hired the pit's former miners to maintain the underground workings and act as tour guides.
But many are now retiring - and fresh blood was needed.
David Powell from Treharris and Ben Monro from Caerphilly were among 52 who applied for the new jobs as mining craft apprentices.
"I am extremely excited at the prospect of becoming a part of Welsh industrial heritage and to contribute to Big Pit's aims and objectives as a world class museum," said Mr Powell.
Ben Monro added: "I feel passionate about encouraging individuals and families from all backgrounds to visit our national museums and look forward to increasing understanding and appreciation of our history and culture."
The pair will now undergo vocational training, with hands-on experience working next to members of the maintenance team, as well as becoming part-time members of the local Mines Rescue Team.
It is hoped after six months of training they will become underground guides at the pit.
Mine manager Huw Jones said: "The apprenticeships are an important part of the succession plan at Big Pit and will help to ensure that the public can continue to enjoy the underground experience at the museum and learn about the history of the mining industry in Wales.
"We are hopeful that the apprenticeship initiative will continue year on year."


Multiple TT winner Michael Dunlop went quickest in the opening practice session for the 2016 Festival of Motorcycling on Monday.

The first session for the event, which includes the Classic TT and Manx Grand Prix, also saw newcomers getting their first untimed laps of the TT course.
Dunlop, from Northern Ireland, set the fastest lap of the session on his Classic TT Superbike at 121.133mph lap.
The second practice session will be held on Tuesday.
Steve Mercer (118.203mph) and Ivan Lintin (117.995mph) were the next quickest in the session - also on their Superbikes.
Welshman Ian Lougher (113.363mph) leads Lightweight practice with John McGuinness fastest in the Classic TT class and Michael Rutter leading the Junior Classic TT class.
Clerk of the Course Gary Thompson warned riders of damp patches around the course ahead of the session.
Alan Thomas from Wales was reported off at the Water Works but organisers said he was "uninjured".
The first races get under way on Saturday.
Michael Dunlop - 121.133mph
Ian Lougher - 113.363mph
John McGuinness - 107.089
Michael Rutter - 99.501mph


The Cannabis Is Safer Than Alcohol party (Cista) has called for a Royal Commission to review current UK drug laws.

The party launched its Northern Ireland manifesto in Belfast on Tuesday.
It claims vulnerable people are missing out on medical treatment due to the refusal of governments to treat cannabis the same way as alcohol.
The party aims to achieve the decriminalisation of cannabis and the establishment of a regulated industry.
It was founded earlier this year by Paul Birch, the co-founder of social networking site Bebo, and is fielding four candidates in Northern Ireland.
Mr Birch said he accepted Cista was a "single issue party".
He said he believed there was no debate on whether cannabis was safer than alcohol.
Mr Birch said successive governments had pursued a "pointless" drugs policy that "doesn't do anyone any good".
"It's just a waste of police money and time and we are flushing tax revenue away," he said.
"Medical cannabis is one of the victims of the war on drugs - that's why medical cannabis is not available in the UK."


Three explosions have hit a bus carrying the German football team, Borussia Dortmund, to a Champions League match at their home stadium.

Player Marc Bartra had to have an operation after breaking a bone in his wrist. No other players were hurt.
Dortmund police said the vehicle was targeted deliberately but said it's too early to know whether it was a terrorist attack.
The match against Monaco has been delayed until 5.45pm (UK time) on Wednesday 12 April.
Dortmund Police said there will be extra security and more police officers at the delayed match to make sure people are safe.

Fans at the 80,000-seater Signal Iduna Park in Dortmund, who had already arrived for the match, were told to stay there until it was safe to leave.
The stadium was later evacuated safely and police thanked the fans for their co-operation.
Borrusia Dormund and their fans used social media to help find the thousands of Monaco supporters, who had travelled to Germany for the match, a place to stay for the night.


Police investigating the disappearance of a Fraserbugh man have launched a fresh appeal for information six months after he was last seen.

Shaun Ritchie, 20, was last seen with friends at a remote woodland area near Strichen on the night of Friday 31 October into the Saturday morning.
Police Scotland said it had been one of the biggest ever search operations carried out by the force.
There was no evidence, said the police, that he had been the victim of a crime.
Insp Stewart Drummond said: "The searches carried out to locate Shaun have been extensive and also challenging due to the difficult terrain.
"Items of Shaun's clothing were recovered as part of the early stages of the enquiry which would have placed him in the Greenburn area.
"If Shaun has walked on from this area, as appears to be the case, we have no indication of the direction he has taken, which compounds further searches due to the size of terrain already searched."
He explained:  "We have interviewed a number of people, including those who were with Shaun on the night he was last seen.
"Although we will always keep an open mind as to the circumstances, there is no evidence to date which would indicate that Shaun has been a victim of any crime.
"We understand this is a difficult time for Shaun's family who just want answers and not knowing where he is or what has happened to him is beyond frustration for them.
"We are therefore again appealing for any information which may assist us in finding Shaun and ask people to come forward and contact Police Scotland."
A CCTV image released earlier showed Mr Ritchie wearing dark grey skinny jeans, a white t-shirt, a grey hoodie and brown trainers.


Sir Rod Stewart has donated cash to a fund set up in memory of a Rangers fan who died in a bus crash at the weekend.

The singer, who supports Celtic, contributed to the fundraising drive for Ryan Baird after getting in touch with former Rangers captain Richard Gough.
Mr Baird, 39, died after the supporters' club bus he was travelling on crashed near Kilmarnock.
The fans were travelling to see Rangers play Partick Thistle at Ibrox stadium.
Mr Gough told the Evening Times: "As soon as it happened Rod got in touch with me and said as soon as a fund was set up I was to let him know. Which I did.
"He made a contribution, which is fantastic, which I have thanked him for. He is a good man."
In Sir Rod's message to Mr Gough, he said: "At sad times like this we are one big football loving family. RS(Celtic)."
The accident left 18 other people in hospital.
Mr Baird, originally from Northern Ireland, had been living in Sanquhar, Dumfries and Galloway.
He was travelling with the Nith Valley Loyal Rangers Supporters Club.
Meanwhile, Rangers players have visited injured fans in hospital.
The supporters' club thanked Rangers for all their support and said managing director Stewart Robertson, manager Mark Warburton, assistant manager David Weir and players had met with supporters at their base on Tuesday.
They said four first-team players have also visited the two fans who are still in hospital.
The supporters' club said in a statement: "These visits have been valuable in helping our members, especially the youngsters, start to come to terms with what has happened.
"Rangers directors have been in touch with us and the family daily. The Nith Valley loyal and our community will never forget what they've done for us."
Police said inquiries into the crash continue.


Italy will host the Ryder Cup for the first time in 2022 at the Marco Simone course in Rome.

It will be the 44th edition of the biennial team tournament between Europe and the United States of America.
Europe has held the event outside of England on only five other occasions - Muirfield (1973) and Gleneagles (2014) in Scotland, Spain (1997), Republic of Ireland (2006) and Wales (2010).
Europe defend their title in Minnesota next year before France hosts in 2018.
Italy beat Austria, Germany and Spain in the bidding process.
European Tour chief executive Keith Pelley said: "History has shown time and again that the Ryder Cup is pure theatre with the players the stars.
"There is no question that the Eternal City of Rome will provide a wonderful backdrop for one of the great occasions in world golf.
"We have exciting plans for the development of The European Tour and our international schedule for the benefit of all our players, and Italy shares this ambition.
"Their commitment to the Italian Open will provide an inspiring benchmark."
The Marco Simone course, 17km from the centre of the Italian capital, will be reconstructed to meet the standards for the tournament.


Bristol City Council has bought an eyesore site in the city centre, which it says will be key to one of the UK's largest urban regeneration projects.

The former sorting office site has been derelict for more than 17 years.
The mayor said the site presented an "awful arrival" for people coming in to Temple Meads station and buying it was vital to transforming the area.
The Taxpayers' Alliance has criticised Bristol's "extraordinary" commercial property portfolio.
The acquisition of the 2.1 hectare (5.2 acre) former Royal Mail site, close to the planned Â£91m arena, is seen as a key site in the Bristol Temple Enterprise Zone.
Bristol Mayor George Ferguson told BBC Bristol it had cost "under Â£6m" and marked a "real step change" in the transformation of the area behind Temple Meads station.
"It's been one of my main aims to deal with this terrible eyesore, this awful arrival to Bristol."
"When you're entering a wonderful city like Bristol from London on the Great Western Railway, you expect a much better arrival."
The Taxpayers' Alliance, which campaigns for lower taxes, says the council owns buildings housing a nightclub, 25 restaurants, 22 farms and 198 shops, following a Freedom of Information request.
Spokesman Tim Newark said: "It seems ridiculous at a time when Bristol City Council is pleading poverty and putting up Council Tax that it is sitting on commercial property assets worth hundreds of millions of pounds."
Mr Ferguson said property was "a very important part of our holdings and that actually enables us to keep the taxes lower than they might otherwise be".


World number one Andy Murray gained revenge for last Thursday's defeat by Albert Ramos-Vinolas in Monte Carlo by beating the Spaniard to reach the last four of the Barcelona Open.

The Scot dug deep to claim a 2-6 6-4 7-6 (7-4) victory in a match that lasted two hours 59 minutes.
He recovered from two breaks of serve in the third set, his opponent serving for the match at one point.
Murray now faces Austria's Dominic Thiem in the last four.
Ramos-Vinolas, who is at a career-high world ranking of 19, capitalised on a string of unforced Murray errors to take the first set but was pinned back in the second as the Scot battled back to level.
In Monte Carlo, Murray had led 4-0 in the final set before capitulating to a defeat to Ramos-Vinolas.
In Barcelona, it was the Spaniard who held a final set lead, winning the first two games before injuring his foot attempting to receive a volleyed return, which led to a lengthy period of treatment.
The incident initially benefited Murray, who won the next three games, but Ramos-Vinolas steadied the ship and looked set for victory after breaking in the ninth game.
However, Murray dug deep and immediately broke back before taking the match to a tie-break that he largely dominated and clinched on his second match point.
"It was obviously a very tough match," said Murray. "It was kind of the opposite of the match we had last week where probably  today he deserved to win. He created a lot more chances, he served for the match and couldn't quite get it.
"Last week I had 4-0 [in the third set], I felt like I had all of the  chances. Sometimes on clay matches happen this way, so very happy to get through."
Rafael Nadal, a 10-time winner in Barcelona, joined Murray in the last four courtesy of a 7-6 (7-1) 6-2 win over Korean qualifier Hyeon Chung.
The Spanish 14-time Grand Slam champion, 30, takes on Russia's Karen Khachanov or Argentine Horacio Zeballos in the last four.
Britain's Aljaz Bedene continued his winning run with a straight-sets win over second seed Ivo Karlovic to reach the Hungarian Open semi-finals.
British number four Bedene broke the Croat's serve early in both sets on his way to a 6-4 6-3 victory, and a 15th-straight win.
The 27-year-old, ranked outside the top 100 at the beginning of March, has climbed to world number 68.
He faces fourth seed Fernando Verdasco or fellow qualifier Laslo Djere next.
Bedene came through qualifying in Budapest to reach his first ATP Tour semi-final since January 2016.
He also won back-to-back titles on the second-tier ATP Challenger Tour earlier this month.
The clay court specialist has now won 22 of his past 23 matches, with the only defeat coming on hard courts at the Miami Masters.


UKIP could have its first AM when the Welsh assembly elections are held in 2016, an academic has said.

Dr Rebecca Rumbul from the Wales Governance Centre thinks the party could win a seat as some are won by a form of proportional representation.
But she does not believe it will gain any MPs in Wales at next year's general election because of the "first past the post" system.
She spoke after UKIP won a by-election to see its first MP elected in England.
Thursday's victory for Nigel Farage's party led Prime Minister David Cameron to say the general election would be "the most important in a generation".
Meanwhile, Labour leader Ed Miliband said his party needed to "reach out" to disaffected voters.
A recent BBC Wales poll suggests support for UKIP ahead of the general election has doubled from 7% to 14%.
UKIP has already said it plans to open an office in the south Wales valleys.
UKIP Welsh MEP Nathan Gill predicts the party's current momentum can carry them to victory in at least one Welsh seat next May.
But Dr Rumbul told BBC Radio Wales it was more likely the party would be successful in the assembly elections in 2016.
She said people tend to vote differently in the different types of elections with UKIP performing strongly in the European elections in May in comparison to the general election in 2010.
"Because of the way the general election system works - the first past the post system - I do think it's unlikely that UKIP will get an MP from Wales," she said.
"However, our system in the Welsh assembly is much different and under that system it's actually quite likely that we may see some UKIP AMs returned in 2016."
The Wales Governance Centre at Cardiff University examines issues affecting Wales covering law, politics and government.


Thousands of fireworks exploded in the night sky during a national pyrotechnic contest.

18 August 2016 Last updated at 13:46 BST
The British Fireworks Championships saw six display companies vying for the champion's title.
The competition is held in the natural amphitheatre of Plymouth harbour.
This year's winner was Northampton company Gala Fireworks, who were the final team to perform on Wednesday night at the end of the two-day event.


Plans to build a large biomass plant and eco park on the site of the former Anglesey Aluminium works near Holyhead have taken an important step forward.

The UK government has approved design changes to the proposals by Chester-based Lateral Power.
Plans for a biomass plant at the site were first put forward in 2009 and a licence was granted in 2012.
The factory could create 400 new jobs with an extra 600 in the construction phase.
A spokesman for the Department of Energy and Climate Change (DECC), which first granted permission for the plant in 2011, said ministerial consent had been given to allow for some technological changes to the biomass generating station at Penrhos Works.
The plant is expected to generate 299MW of electricity, which is enough to power about 300,000 homes.
Anglesey Aluminium smelting works shut in 2009 with the loss of nearly 400 jobs.


This stripy little cutie is a baby tapir that was born on Thursday morning.

29 May 2015 Last updated at 11:20 BST
Tapirs are relatives of the horse and rhino and are usually found in South America.
This one was born at a zoo in Prague, in the Czech Republic.
Once the baby is about two months old, he will lose his stripes and turn brown.


Singer and actress Olivia Newton-John has revealed she has breast cancer again, 25 years after recovering from her original diagnosis.

The Grease star has postponed upcoming tour dates after discovering that severe back pain she has been suffering is a result of the disease spreading to her spine.
The 68-year-old was due to perform across the US and Canada next month.
She will have treatment and expects to return to the stage later in 2017.
Last week, the four-time Grammy award winner cancelled planned meet-and-greet events for the upcoming tour dates due to "severe back pain".
A statement on Tuesday said: "The back pain that initially caused her to postpone the first half of her concert tour, has turned out to be breast cancer that has metastasized to the sacrum.
"In addition to natural wellness therapies, Olivia will complete a short course of photon radiation therapy and is confident she will be back later in the year, better than ever, to celebrate her shows."
After surviving her initial cancer diagnosis in 1992, Newton-John became a prominent campaigner for others facing the disease, as well as on other health issues.
She set up the Olivia Newton-John Cancer and Wellness research centre in Melbourne, Australia. It was partially funded by a sponsored walk along the Great Wall of China, aided by celebrity friends including Sir Cliff Richard and Joan Rivers.
Tuesday's statement advised ticket holders for her upcoming concerts to contact the venue about refunds.


In a quintessential suburban backyard scene, somewhere in Australia, a nervous man stands up to make a barbecue-stopping announcement.

As the others pass around barbecue sauce, he declares: "Mum, Dad, I like tomato sauce. I'm a tomato sauce man. Always have been."
His father, momentarily overwhelmed, gives him an emotional hug. The son shares a kiss with his husband - both are wearing wedding rings.
"A simple difference shouldn't be a big deal," ends the ad, part of a campaign to legalise same-sex marriage in Australia.
Ahead of Sydney's annual Gay and Lesbian Mardi Gras on Saturday, the ad's makers used a quintessential Australian scene to convey their message, and they're not the first to do so.
Last year, Malcolm Turnbull became the first sitting Australian prime minister to attend the Mardi Gras.
But while he personally supports the legalisation of same-sex marriage, the issue has divided his conservative government, and a proposal for a vote on the issue was blocked in parliament last year.
This set the issue back indefinitely, to the frustration of rights activists. Mr Turnbull has said he won't be going to Mardi Gras this year, as he has "other things" on.
Armand de Saint-Salvy, who directed the tomato sauce ad, said it was a way of reigniting the marriage equality debate.
"I wanted to show a typical Aussie family where there was a same-sex married couple and it wasn't a big deal, it was part of everyday life, which hopefully will be the case in a few years," he told the BBC.
"I think everyone can relate to family coming together. That's really what the message is: equal love."
Dee Madigan, an advertising expert, said the scene bears similarities to adverts for beer, and works by taking the issue into the backyard.
"It's a really 'blokey' ad and I think that's the power of it," she told the BBC. "It's not high camp."
While the setting may seem an unlikely choice, she said it would appeal to mainstream audiences.
"The ordinariness of it plays into this sense - that I think everyone has now - which is, 'oh God, let's just stop making such a big deal and just get on with it'," Ms Madigan said.
In a similar way to watching sport, putting on a "barbie" is often a social leveller in Australia.
"Sausage sizzles" have become a staple of election days in a nation where voting is compulsory. Competitions testing skill at the grill have been held. The Queen even concluded an 11-day tour of Australia by attending a huge barbecue.
Australian author Mark Thomson, who wrote a book on barbecues, said the backyard ritual holds a unique place in national culture.
"A barbecue is a profoundly egalitarian social setting," he said.
"Australians have remarkably few social rituals that bond us in ways that we all recognise. You go to something like an Australian citizenship ceremony and it's never quite as good as a barbecue with friends."
So it is no surprise that barbecue-themed adverts have increasingly explored issues such as multiculturalism and responsible drinking.
Examinations of social issues have also featured in ads for products, occasionally bringing controversy.
A perennial campaign to convince people to eat lamb on Australia Day is perhaps the best-known example.
The ads for Meat & Livestock Australia (MLA) typically involved scenes of jingoism, and recently faced criticism, prompting a rethink in 2017. This year's commercial changed tack to celebrate multiculturalism and confront controversy surrounding Australia Day.
In the video, indigenous Australians discuss being the "first here" as boats arrive from the Netherlands, Britain, France, Germany, China, Italy, Greece, Serbia and New Zealand. The advert ends by asking "aren't we all boat people?", accompanied by an all-inclusive barbecue.
The advert received widespread attention, much of it positive, but still drew criticism for exploring a sensitive subject as "a marketing ploy".
MLA group marketing manager Andrew Howie said the lamb advert was designed to reach younger audiences.
"You have to be able to create something that has enough currency that it starts to flood their social media feed," he said.
Ms Madigan agreed social media marketing in particular relied on viral attention.
It was not surprising that marketers were turning to backyard scenes to explore complex concepts, Mr Thomson said.
"It's great that people are using those things to sneak in ideas about who we are," he said.
"The barbecue is not about to disappear anytime soon."


Police in Ireland have described the death of a woman in County Galway as a tragic incident.

The 64-year-old woman has been named locally as Teresa McDonagh.
It is believed she died after being attacked by two Bullmastiff dogs at a family member's home on Sunday afternoon.
Emergency services were called to the scene but the woman was pronounced dead after efforts to resuscitate her failed.
Irish national broadcaster RTÃ‰ reports that nobody was home when the victim arrived at the property at lunchtime.
Emergency services were only alerted after the occupants returned to the home at 15:00 local time and discovered Mrs McDonagh.
Her body has been taken to University Hospital Galway, where a post-mortem examination will take place.
Bullmastiffs are listed in Ireland's 1998 Control of Dogs Act, which means they must be securely muzzled in public, but there are no restrictions on them on private property.
The dogs involved in the attack were later put down.


German Chancellor Angela Merkel is to use her New Year's speech to urge Germans to see the influx of refugees as an opportunity for the future.

Warning against support for xenophobic groups, she says "it's important we don't allow ourselves to be divided".
Germany has taken in more than a million asylum seekers this year, far more than any other European country.
Europe's response to the migration crisis has been criticised by the outgoing head of the UN refugee agency.
Antonio Guterres told the BBC that the EU had been and continued to be "totally unprepared" for the arrival of refugees and "unable to put its act together".

Migrants offered 'bad weather discounts'
The migrants reaching Europe by land
More than one million refugees and migrants have reached Europe by sea since the start of 2015, according to the UNHCR. About half are from Syria.
Germany has been the destination of choice for many of those arriving by sea, and it has also attracted large numbers of migrants from Balkan states.
In her New Year's address to be broadcast on Thursday evening, Mrs Merkel acknowledges that the past year has been challenging but she repeats a message she has used on several occasions: "Wir schaffen es" - we can do it.
She warns that integrating the new arrivals will take "time, strength and money", according to a pre-released text of the speech recorded on Wednesday.
"I am convinced that if we tackle the huge task posed by the influx and integration of so many people in the right way today, then this will represent an opportunity for us tomorrow."
The chancellor does not specifically mention Pegida, which has held large "anti-Islamisation" rallies in Germany, but urges Germans not to follow "those with coldness, or even hate in their hearts, and who claim the right to be called German for themselves alone and seek to marginalise others".
The migrant crisis has strained relations between EU member states, with some countries introducing temporary border controls despite the bloc's principle of passport-free movement.
Criticising the EU's response, Mr Guterres - who is stepping down as UN High Commissioner for Refugees after 10 years - said divisions in Europe meant countries had failed to act.
"For the first time, in meaningful numbers, refugees and other migrants came to Europe - and Europe was totally unprepared for that," he said.
"But not only it was unprepared then, it is still unprepared today. It was unable to put its act together."
Instead, he said, countries had served their own interests - discouraging migrants from entering their borders by introducing increasingly harsh policies.
Some states such as Hungary, Austria and Slovenia have resorted to building fences along their borders to manage the arrivals of thousands of migrants.
Meanwhile, a Danish government proposal to seize assets of asylum-seekers to help fund their stay has drawn sharp criticism.


Ministers campaigning to leave the European Union say recipients of EU funding would get the same money if the UK votes to leave.

EU funding projects for areas including farming, science, and culture would be continued until 2020, they said.
Priti Patel said government would have "options and choices" after Brexit with "more than enough money" to go around.
But Remain campaigners said leaving the EU would "wreck Britain's economy" and trigger public spending cuts.
BBC political correspondent Ben Wright said Vote Leave's open letter, signed by ex-London mayor Boris Johnson and ministers including Michael Gove, Chris Grayling and Priti Patel, sounded like "a pledge of a government in waiting".
Vote Leave has no power to make public spending promises - but is trying to reassure recipients of EU money their funding would be safe, he added.
The UK votes on whether to remain in the EU or to leave on 23 June.
In other developments:
The ministers' letter claims that as an EU member, the UK is liable for billions of pounds in tax refunds for big businesses, saying savings could also be made through taxing offshore companies if it votes to leave.
"It is therefore clear that there is more than enough money to ensure that those who now get funding from the EU - including universities, scientists, family farmers, regional funds, cultural organisations and others - will continue to do so while also ensuring that we save money that can be spent on our priorities," it adds.

The letter also said the "official bill" for the UK's EU membership was over £350m a week.
Vote Leave's use of the £350m figure has been criticised by the UK Statistics Authority and the Institute for Fiscal Studies as "potentially misleading", as it does not include the UK's rebate - a deduction on the UK's overall contribution negotiated by Margaret Thatcher's government in the 1980s.
But in the letter, also signed by Julian Brazier, James Duddridge, George Eustice, Penny Mordaunt, Dominic Raab, Iain Duncan Smith, Desmond Swayne, Theresa Villiers, and John Whittingdale, Vote Leave said the UK had no control of the money and "could not count" on the rebate.
It has previously called for an extra £100m a week to be spent on the NHS if the UK leaves.
How the UK is affected by the Common Agricultural Policy and EU fishing policies.
Ms Patel, who is an employment minister, denied that Vote Leave was making a series of unfunded promises, telling the BBC that the cash injection for the NHS and a cut in VAT on domestic fuel were its only two firm commitments of where money could go after Brexit.
"We are saying very clearly when we take back control of the money we spend to the European Union, the government of the day will have options and choices about how they choose to spend that money," she told Radio 4's Today.
However, she also suggested action could be taken to relieve pressure on school places and she questioned "why any government" would want to reduce support for "immensely important" parts of British society, such as universities, science base and the farming industry.
"We know that there would be more than enough money to ensure that those who currently get that funding from the European Union, that money would still exist and it could still go there to those priorities."
What are the polls saying about which way the UK will vote on 23 June?
Britain Stronger in Europe dismissed the analysis and said the Leave campaign had made 24 spending commitments totalling over £113bn.
Alan Johnson, head of Labour In, said it would only take a 0.6% reduction in economic output after a vote to leave to "eradicate the £8bn that is sent to the European Union and distributed through farming subsidies".
"It is fantasy economics," he told Today. "That money does not exist."
Former chancellor Alistair Darling said "just about every economic expert" had said leaving the EU would "wreck" the UK economy.
He added: "The Leave campaign have had to abandon their key spending pledge after using misleading figures and have been caught pledging their claimed saving 10 times over."
The Leave campaign has also accused EU officials of spending taxpayers' money on "outrageous and excessive" expenses.
Taking examples from a website detailing expenditure by the European Commission, it claimed an "exorbitant" amount of money went on "jollies", including visits to luxury hotels and resorts, restaurants and private jets.
The European Commission said many of the claims were inaccurate. Officials almost always used economy class, it said, and private jets were only hired when other transport was not available.


About 2,500 homes on the Essex coast are being evacuated as the area prepares for a potential tidal surge.

Chief fire officer David Johnson said the homes in 61 streets in Jaywick were being evacuated with flood levels expected to reach 50cm (20in) from the top of the sea wall.
He said people should start packing some belongings and those who could voluntarily leave the area should.
Three severe flood warnings, indicating danger to life, have been issued.
They include the coast from Clacton to Lee Wick and at Mistley, Brantham and West Mersea.
More than 20 severe flood warnings are in force in Norfolk, Suffolk and Essex.
Mr Johnson said the whole of Jaywick would be evacuated.
He said: "The information that we have from the Environment Agency is that the water is going to be about half a metre from the top of the sea defences, but obviously with some significant winds blowing there will be waves over the top of those defences.
"The decision has been taken to evacuate Jaywick as best we can as a purely precautionary exercise and I would urge people not to panic."
People will be evacuated to school buildings in the Clacton area, he said.
"If people are able to voluntarily leave and stay with friends and relatives overnight that is always a good idea and will be very helpful."
He said police officers would be knocking on every door in the village and asking people to leave.
"We can't force people to evacuate their homes, but as a purely precautionary exercise it would be sensible to do so," said Mr Johnson.
The rail line between Norwich and London was disrupted by damage to overhead wires caused by falling trees in Diss, Manningtree and Wivenhoe.
A Greater Anglia trains spokesman said: "At present there are no services in either direction between Colchester and Norwich.
"There is currently a reduced service running between London and Colchester in both directions with delays up to 60 minutes.
"Services between London and Southend/Southminster and stopping services between London and Shenfield are running a full timetable this evening."

Human Rights Watch says it is confident photos smuggled out of Syria by a defector in 2013 showing 6,786 people who died after detention are authentic.

The group carried out a nine-month investigation into the 53,000 images handed to the opposition by a military police photographer, codenamed Caesar.
Researchers interviewed former prisoners, defectors, forensic experts and families of the disappeared.
Syria's government and its allies had questioned the images' authenticity.
They were first published in January 2014 in a report by three former war crimes prosecutors that was commissioned by Qatar, which supports the political and armed opposition in Syria.
In an interview earlier this year, President Bashar al-Assad said: "You can bring photographs from anyone and say this is torture. There is no verification of any of this evidence, so it's all allegations without evidence."
But on Wednesday, Human Rights Watch laid out in a new report what it said was new evidence regarding the authenticity of the Caesar photographs, identifying a number of the victims and highlighting some of the key causes of death.
The US-based group said it had located and interviewed 33 relatives and friends of 27 victims whose cases researchers verified; 37 former detainees who saw people die in detention; and four defectors who worked in Syrian government detention centres or the military hospitals where most of the photographs were taken.
Syria torture report
In pictures: Syria accused of torture
Using satellite imagery and geolocation techniques, HRW confirmed that some of the photographs of the dead were taken in the courtyard of the 601 Military Hospital in Mezzeh, a western suburb of the capital Damascus.
The group also identified a coding system for the cards placed on the bodies.
"We have meticulously verified dozens of stories, and we are confident the Caesar photographs present authentic - and damning - evidence of crimes against humanity in Syria," said Nadim Houry, HRW's deputy Middle East director.
HRW said its report focused on 28,707 of the 53,275 photos smuggled out of Syria by Caesar that, based on all available information, showed the bodies of at least 6,786 people who died in detention or after being transferred from detention to a military hospital.
The remaining photographs are of attack sites or of bodies identified by name as of government soldiers, other combatants, or civilians killed in attacks, explosions or assassination attempts.
Most of the victims were detained by just five intelligence agency branches in Damascus, and their bodies were sent to at least two military hospitals in Damascus between May 2011, when Caesar began copying files and smuggling them out of his workplace, and August 2013, when he fled Syria, HRW said.
Forensic pathologists from Physicians for Human Rights analysed a subset of the photos, and found evidence of several types of torture, starvation, suffocation, violent blunt force trauma, and in one case, a gunshot wound to the head.
Among the 27 victims identified by HRW - all of whose families spent months or years searching for news of their whereabouts, in many cases paying huge sums to contacts and middlemen - were Rehab al-Allawi, a boy who was 14 at the time of his arrest for having an anti-Assad song on his phone, and student Rehab al-Allawi, who was 25 when she was detained while working with an activist group.
The former detainees, held in the same places as most of the victims, told HRW that guards kept them in severely overcrowded cells with very little air circulation, gave them so little food that they grew weak, and often denied them the opportunity to wash. Skin diseases and other infectious diseases proliferated, and the detainees said guards denied them adequate medical care.
"Many of the former detainees who were held in these nightmarish conditions told us they often wished they would die, rather than continue suffering," Mr Houry said.
The Syrian Network for Human Rights, an activist group, has documented the arrest and detention of more than 117,000 people in Syria since the uprising against Mr Assad began in March 2011.


A "dangerous" prisoner who wrote letters threatening to kill people and have sex with their corpses has been jailed for 45 years.

Richard Ford, 38, was serving a 30-month sentence for possessing a knife when he made the threats from his cell.
A judge passed the "highly unusual" sentence after hearing of Ford's fear he would enact his "sadistic urges".
He acknowledged the term "may be controversial" but said it was necessary to protect the public.
Ford, who has spent most of the last 14 years in jail, was being held at HMP Nottingham last January when he passed a series of notes to prison officers containing a list of potential victims.
He named several prison officers, a fellow inmate, a district judge, a police officer and a former partner.
Sentencing at Lincoln Crown Court, Judge Michael Heath told Ford, who admitted ten charges of making a threat to kill, the case had caused him "very considerable anxiety".
He said Ford, who had expressed a desire to never be released from prison, was "plainly dangerous" and "would pose a grave and immediate danger to the public".
But, the judge said, he was bound under the law to pass a sentence which was not "wholly disproportionate" to the offence of making threats to kill, which carries a maximum ten-year jail term.
"Achieving both of these aims in this case is impossible," he said.
By Clive Coleman, BBC legal correspondent
This case is truly exceptional, and the sentence passed shows the ability of the criminal justice system to do something exceptional in response to it.
Most defendants who are as dangerous as Richard Ford would have committed offences which carry a life sentence. A few years ago another option would have been an indeterminate sentence for public protection, or IPP.
These were designed to protect the public against those whose crimes were not serious enough to merit a normal life sentence but who were seen as too dangerous to be released when the term of their original sentence had expired. They were abolished in 2012.
Threats to kill carry a maximum sentence of ten years.  Normally a judge will balance the need to protect the public with the fact that a sentence must be proportionate to the crimes committed. Judge Michael Heath made it clear that in these exceptional circumstances he erred on the side of protecting the public and so passed a sentence which might ordinarily seem disproportionate to the crimes committed.
The judge imposed a mix of consecutive and concurrent nine-year jail terms, adding up to a total of 45 years.
"I realise that the overall length of the sentences I am going to pass is highly unusual and may be controversial but I pass them because I deem them to be the only adequate way to protect the public in your case," he said.
"You say you don't feel that you can stop yourself from acting upon your sadistic urges. Those urges are to kill and have sexual intercourse with the corpses of those whom you kill.
"You have made it clear to me that you do not wish to be released from prison. If you are released you think you will get drunk, obtain a weapon and kill."
Isabelle Wilson, in mitigation, said Ford did not feel he was safe to be released and wanted to receive treatment either in a prison or in a hospital setting.
"The thoughts he discusses are concerning but at least he is willing to speak about those thoughts openly," she said.
The court was told Ford had been assessed by a number of psychiatrists but there was no recommendation that he receive hospital treatment.
Judge Heath said that, therefore, he was not legally able to make a hospital order.
The court was told Ford had convictions from 2002 and 2003 for indecency offences against men.
He was also convicted for possession of a knife in a public place in 2011, 2013 and 2014.


A powerful car bomb has exploded outside a state security building in northern Cairo, Egyptian security officials say.

The blast, which was felt across large parts of the Egyptian capital, injured 29 people, six of them police.
The explosion happened in the early hours of Thursday morning. There were no reports of any deaths.
The militant group Islamic State (IS) says it carried out the attack "to avenge Muslim martyrs".
The statement was not attributed to IS's known branch in Egypt, Sinai Province, but simply had a logo reading "Islamic State, Egypt".
A BBC correspondent in Cairo reports a heavy police presence on the streets.
Residents across Cairo reported hearing and feeling a large blast just before 02:00 local time (00:00 GMT).
There have been several bomb attacks by Islamist militants in Cairo this year.
"A man suddenly stopped his car in front of the state security building, jumped out of it and fled on a motorbike that followed the car," a ministry statement said.
"The car exploded wounding six policemen," it added.
The blast left a crater in the street and partially destroyed the building. Locals said glass from blown-out windows was strewn across several streets nearby.
Sinai Province militants based in northern Sinai have been behind many of the recent bomb attacks in Cairo.
Thursday's bomb comes just days after President Abdul Fattah al-Sisi approved new counter-terrorism laws designed to fight the growing jihadist insurgency.


Foxconn has lined up several high-profile US technology firms to join its bid for Toshiba's memory chip unit.

Apple and Dell are among the firms involved in the consortium, said Foxconn chief executive Terry Gou.
Foxconn, the world's biggest contract electronics manufacturer, makes the iPhone for Apple.
Mr Gou said Amazon could also come on board, while talks continued with Google owner Alphabet, Microsoft and Cisco Systems.
Apple declined to comment, while others did not respond to requests for comment.
It was not clear say how much Foxconn planned to offer for the division, which analysts have valued at about $18bn (Â£14.2bn).
Earlier this year it was reported that Foxconn could offer as much as $27bn for the unit. It was not clear why the potential bid was so much higher than its mooted value.
Toshiba is selling some or all of its chip unit to cover huge losses in its nuclear division, Westinghouse Electric, which has filed for bankruptcy.
It was the latest headache for the Japanese conglomerate. In 2015, Toshiba's chief executive resigned after the firm said it had overstated profits for years. It is also set to post another annual loss.
Toshiba: What's going wrong?
Toshiba shareholders angry as chip unit sale approved
The memory chip unit is said has attracted interest from several firms including Western Digital, Micron Technology, SK Digital and Broadcom.
Previously, it was reported that Foxconn would offer $27bn. Foxconn acquired Japan-based Sharp last year.
Toshiba hopes to announce a deal by mid-June, with shareholders voting on the sale on 28 June.
The Japanese government plans to examine the national security considerations of a deal. That could present a challenge to Taiwan-based Foxconn, which does much of its manufacturing in China.


Harry Potter creator JK Rowling says she is "delighted" Johnny Depp has a role in Fantastic Beasts and Where to Find Them and its planned sequels.

The British author said Depp had done "incredible things" with the character of dark wizard Grindelwald.
Depp makes a fleeting appearance in the first Fantastic Beasts film but will play a larger part in its sequel.
Director David Yates said Depp was an "extraordinary talent" as well as "a huge Potter fan".
"He was beyond excited about working on this material," said Yates at the world premiere of Fantastic Beasts in New York.
The film, a prequel to Rowling's wizarding series, is set 70 years before the events depicted in the first Potter book.
In those stories, Grindelwald was a good friend of Albus Dumbledore, future headmaster at the Hogwarts School of Witchcraft and Wizardry.
But their close relationship eventually broke down - a plot thread set to be explored in the Fantastic Beasts series.
Speaking on Thursday, Rowling said future Fantastic Beasts films would show Dumbledore "as a younger man... at what I think was the formative period of his life."
Yet she refused to confirm speculation that the character would be seen in a gay relationship with Depp's character, simply telling reporters to "watch this space".
The author admitted she had been "in a kind of a bleak mood" as she prepared to travel to the US in the wake of this week's presidential election results.
But she said that working on the second film's screenplay during her flight had made her feel "a whole lot better".
Eddie Redmayne plays Newt Scamander in Fantastic Beasts, a "magizoologist" who travels to New York to continue his studies of magical creatures.
Fantastic Beasts and Where to Find Them has its UK premiere in London next week ahead of its release on 18 November.

John Lewis sales rose 5.1% over "three peaks" of the Christmas period, the retailer has said.

Black Friday, Christmas and post-Christmas trading at John Lewis was boosted by online sales, which rose 21.4%, offsetting a fall in store sales.
Like-for-like sales at Waitrose, which is part of the same group, fell 1.4%.
John Lewis Partnership chairman Sir Charlie Mayfield told the BBC that "grocery is challenging".
However, he said: "We're pleased with our overall results, we think they'll be pretty much in line with the market."
He added that John Lewis' Black Friday sales had been "more heavily weighted towards online" than in previous years, and that its shops had not been as busy as on previous Black Fridays.
John Lewis sent out 18% more parcels than a year earlier in the Black Friday sales period - peaking at five parcels a second in its busiest hour, John Lewis Partnership said in a statement.
Sir Charlie added that shop sales in John Lewis' post-Christmas "clearance" sales had risen 16%.
The employee-owned firm, which runs 46 John Lewis shops, shrugged off unusually mild December weather as fashion, home and technology sales were boosted.
The mild weather adversely affected retailers including Next, which said on Monday that its trading performance in the run-up to Christmas had been "disappointing".
In the six weeks to Saturday 2 January, total sales at John Lewis Partnership were up 4.1% from the same period last year to Â£1.8bn.
UK supermarkets have been engaged in a long-running price war, while discounters Aldi and Lidl have also been steadily taking market share from the biggest grocers.
Sir Charlie said Waitrose had seen a growth in customer numbers of about 7%, but grocery was "a tough market" which was deflationary.
"Prices are falling. The fact is, if broccoli is half price, you and I have to eat twice as much for us to make the same money," Sir Charlie said.
Waitrose peak trade "came particularly late this year", but the firm had record trading days on 23 and 24 December, John Lewis Partnership said.
In December the rate of food price deflation was 0.3%, the same  pace as November's rate, according to British Retail Consortium (BRC) figures.
Non-food prices fell in December at a 3% rate, and overall UK shop prices fell 2%, the retail lobby group said.
"For the last two years and eight months, customers have been able to fill their baskets, whether virtual or physical, and pay less for their goods than the year before," said BRC chief executive Helen Dickinson.
"A number of key commodities in the retail supply chain - in particular, oil which is now trading under $40 per barrel - have fallen dramatically recently and the impact of these falls will continue to make its way through to shop prices for some time to come," she said.
Sophie McCarthy, an analyst at Conlumino, said the John Lewis Partnership's December trading figures had been "robust".
She said that the retailer's "emphasis on quality and service" and its investment in online shopping "continues to be favoured by consumers".
John Lewis had a "surge" in online trading during the period, helped by sales made through mobile devices, she said.
"Click-and-collect orders also rose this year, with half of online orders collected in this way," she added.


Thomas Cook has donated half of a Â£3m compensation payout it received after the deaths of two British children in Corfu to charity, the firm has said.

Christi and Bobby Shepherd, from West Yorkshire, died from carbon monoxide poisoning at the Louis Corcyra Beach Hotel in 2006.
An inquest jury ruled they had been unlawfully killed and said Thomas Cook "breached its duty of care".
The holiday firm was awarded damages against the hotel's owner in 2010.
Thomas Cook said its insurers had taken half of the payout for legal costs. It said donating the remainder to Unicef was "the right thing to do".
Group chief executive officer Peter Fankhauser said: "Thomas Cook has not in any way profited from our claim against the hotel owner.
"In late 2012, we brought a claim against the hotelier for breaching their contract to provide safe accommodation to our customers and to comply with all applicable laws, which was decided in our favour.
"Today I have made arrangements for the full amount - Â£1.5m - to be donated in full to Unicef, the world's leading children's organisation.
"I believe this is the right thing to do and I apologise to the family for all they have gone through."
The children, from Horbury, near Wakefield, were on holiday with their father, Neil, and his now wife, Ruth, when they died.
All four were found by a chambermaid in a bungalow at the hotel.
Their father and stepmother had also become ill and were in a coma when they were found but recovered in hospital.
Thomas Cook was cleared of responsibility at a trial in Greece in 2010 and was awarded damages against the hotel's owner.
The inquest held in Wakefield heard a faulty hot water boiler had been housed in an outbuilding attached to the side of the bungalow where the family was staying.
When previously asked about the compensation it received, a Thomas Cook spokesman said: "After it was clear that the hotel was responsible for the tragedy all parties affected were compensated and Thomas Cook received a compensation that partly compensated for the costs related to the incident."
The company said it was "shocked and deeply saddened" by the deaths.
The charity donation by Thomas Cook follows criticism of the firm from the parents of Bobby and Christi over the weekend.
Neil Shepherd and Sharon Wood accused the travel giant of not apologising over the deaths following the end of inquests last week.
Mr Shepherd and Mrs Wood said it was "disgraceful" an apparent letter of apology from Mr Fankhauser was only brought to their attention by journalists.
In a statement on Sunday, Mr Shepherd and Mrs Wood said: "It is disgraceful that after all we've been through Thomas Cook are still putting us last in the equation.
"We haven't had this 'so called' letter of apology. We have been shown it by the press and feel it is an appalling continuation of Thomas Cook's PR exercise.
"It's not an apology for their wrongdoing but a general offer of sympathy."
Mrs Wood told The Mail On Sunday: "It seems our children's lives are worth only a fraction of Thomas Cook's reputation."
She said the firm should have apologised at the inquest.


Lost BBC radio commentary of England winning the World Cup has been found - 50 years on from their triumph.

Frank McFarlane, who went to Worcester College for the Blind, had recorded the match on reel-to-reel tape by holding a microphone near to a pocket radio.
He mentioned this at a school reunion to a BBC Radio 5 live listener who was "99% certain" the audio was lost and got in touch with the corporation.
The BBC did not keep copies of the radio commentary at the time.
Saturday marks 50 years since England beat West Germany 4-2 in the final.
The listener, James Robinson, said he meets Mr McFarlane, from Oxton in Wirral, once a year at the reunion and about five years after he first mentioned the full recording, it was brought to the reunion.
Mr McFarlane said: "In those days you really weren't supposed to record from the radio and keep things, so I'm waiting for the solicitor's letter."
Kenneth Wolstenholme's famous words for England's fourth goal on BBC TV were: "Some people are on the pitch. They think it's all over. It is now."
Alan Clarke, on the radio, said: "Twenty seconds, twenty seconds, and it's Hurst and Ball charging wide on the right here and there's people on the pitch at the moment.
"And [Hurst] shoots and a goal by Hurst, goal by Hurst, number four and the England players going down on the turf, hugging each other, on their hands and knees.
"And there it is, number four to England."
Mr McFarlane, a "sports fanatic" who said he has also recorded cricket, explained: "[I] did it in the most amateurish old-fashioned way with an external microphone on the table a few inches away from a little pocket radio.
"I thought 'well I'll do this because this will be well worth keeping, I hope.'
"[I] could've made thousands on it, couldn't I?"
Asked for his assessment, he said the radio commentators "kept up with the game very well".
Mr McFarlane said: "[It was] Alan Clarke, Brian Moore, then you moved into others, Des Lynam, Alan Parry, etc. The summariser... hardly said a word unless brought into the commentary."
Radio commentator Brian Moore, who was later ITV's main voice of football, said: "Stiles with a long ball through to Moore and Moore will run for all he's worth after this when he turns it in.
"Can Hurst get a shot in? It's a chance for Geoff Hurst and he's hit the bar. It must be a goal. I would have thought that went in. But he's not given it.
"I thought that hit the bar and went in, Maurice Edelston."
Summariser Maurice Edelston said: "I'm not certain, but yes it's given, it's given and England are in the lead."


(Close): Wall Street markets rose slightly on Friday as the price of oil climbed and investors shook off a poor April jobs report.

The Dow Jones Industrial Average rose 79.92 points, or 0.45%, to 17740.63.
The S&P 500 climbed 6.51 points, or 0.32%, to 2057.14 and the Nasdaq gained 19.06, or 0.4%, to 4736.16.
The US Department of Labour reported the economy added 160,000 jobs in April, analysts had been expecting more than 200,000 additional posts.
The rising price of crude oil following Thursday's gains, however, helped lift stocks.
The price of West Texas Intermediate crude rose 26 cents to $44.59 a barrel.
The price jumped on Thursday after producers around the Canadian city of Fort McMurray closed or cut output in response to a wildfire.
Shares of Chevron edged up  0.44% and Exxon Mobile nudged 0.53% higher.
The online review site Yelp was one of Friday's biggest winners. Its share price rose 23.7% after beating earnings expectations on Thursday.
A major faller was mobile payment company Square fell 21.7% after the company reported a bigger than expected first quarter loss.


Police are searching a park in an area where three severed human feet have been found this year.

Officers are searching in Weston Park East in Bath, where the first foot was found by dog walkers in February.
A second foot was found in a garden of a property in Weston Park in July, and another was found in a garden in nearby Cranwells Park two weeks ago.
Police said they do not believe a crime has been committed and it is likely they were all medical exhibits.
Det Insp Paul Catton, of Avon and Somerset Police, said he "strongly believed" the finds had originated from "an old private collection".
A spokesman said the new search was being carried out "to try to find anything which may be connected to the discoveries".
"All three feet show signs they have come into contact with animals and it is likely that they have been moved to the locations they were found from a specific source," Det Insp Catton added.
"Regulations are significantly stricter these days compared to several decades ago and we believe the source is most probably someone who used the feet as a teaching aid.
"It is also possible these feet may have been found by someone who has then innocently buried them in an attempt to dispose of them and they have then been unearthed by animals, or that animals have disturbed the location they were stored."
Tests on the first foot showed it was human but found very little DNA, and preliminary results from on the second foot were similar.
The third foot, found on 5 August, is still undergoing tests.
Mr Catton said officers were searching the whole of the park and the grounds of a nearby school.
"The school is in a central location to the sites where all three feet have been found and the last thing we want is for a member of the public to come across one of these unpleasant finds.
"We believe someone knows something about where these feet have come from and would appeal for them to get in touch," he added.


Sky TV presenter Eamonn Holmes has apologised after he appeared to link an attack on Manchester United's team bus with the Hillsborough disaster.

Mr Holmes was talking on Sky News about the violence outside West Ham's stadium on Monday evening.
He tweeted later there was no comparison between the events.
Barry Devonside, who lost his son Christopher, 18, said Mr Holmes "should have known better." He added: "Last night was hooliganism.
"There was no hooliganism at Hillsborough."
In apologising, Mr Holmes tweeted: "I was trying to talk about images we never ever want to see again. If anyone concluded anything different accept my humblest & most honest apologies."
The Manchester United supporting broadcaster said on air: "This is going back to the 70s and 80s. Everything that you were seeing that was bad about Hillsborough for instance."
Mr Holmes tweeted after the programme: "Just being made aware of someone trying to use me to stir up trouble re The Hillsborough disaster . How low, how disgusting.
"The Hillsborough families have suffered enough without distasteful sniping like this. For the record there is no comparison between events last night at West Ham and Hillsborough."
He added: "Last night's events do not remotely register in comparison.  I am an honest & decent football supporter and man.  I would never seek to create such an offence.
"Those who are trying to do so are very wrong. Obviously there is no comparison between Hillsborough & the scenes at West Ham last night....
"I apologise unreservedly if anyone thought I was making that connection."


Barcelona are "in a hole" and "finding it difficult to score goals" admitted boss Luis Enrique following their shock Champions League quarter-final defeat.

The holders were beaten 3-2 on aggregate by Spanish rivals Atletico Madrid, who won the second leg 2-0.
"The team are sad. We aren't at our best at the moment, nor our most effective," he said.
"I'm 99.9% to blame, no 100. That's why I am the coach, the most responsible. We all have to improve."
Antoine Griezmann scored both goals for Atletico at the Vicente Calderon, while Lionel Messi failed to net for the fifth club game in a row.
"It is clear that we are not in our best form, especially if you consider how we were playing before, but we need to lift ourselves," added Enrique.
It is only the third time in 11 years that Barcelona have not reached the semi-finals of the Champions League.
They are three points clear of Atletico at the top of La Liga, but have lost three of their past four games in all competitions.
"It was the game we predicted, although perhaps I didn't expect Atletico to play so deep. It wasn't our best day," added Enrique, who won the treble in his first year in charge at Barca.
"We have to stay calm and think that we still have two competitions where we are in the running.
"Everyone can choose the explanation. To give mine I have to analyse the performance. It is not our best time, but it is not the time to be nervous."

The new president-elect of the US, Donald Trump, will visit President Obama at the White House today.

They'll be sorting out how Team Trump will take over power in January.
It could be an awkward meeting, because the two men have often criticised each other in the past.
Donald Trump won the US election to become the new president, beating his opponent Hillary Clinton.
But lots of people were unhappy with the result, and there were protests overnight in some American cities.


The firm behind Dolmio pasta sauces and Uncle Ben's rice says some products should only be consumed once a week due to high salt, sugar or fat content.

Mars Food said it would distinguish between "everyday" and "occasional" items on packs and on its website.
The company said some foods were higher in salt, sugar or fat to maintain the "authentic" taste of products.
The advice is part of its Health and Wellbeing Ambition to "create and promote healthier food choices".
Mars told the BBC that just 5% of its products would be labelled "occasional".
These include Dolmio lasagne sauces, pesto, and carbonara and macaroni oven kits.
Mars said its website would be updated over the next few months with a list of "occasional" products to be eaten not more than once a week, and "everyday" ones.
Those products, including Uncle Ben's oriental sauces, are to be reformulated over the next five years to cut salt, sugar or fat.
Shoppers will see the new guidance appearing on websites in the coming months.
Mars said its "nutrition criteria" has been developed based on recommendations from leading public health authorities such as the World Health Organization.
It supports the salt-reduction strategies of bodies such as the UK Food Standards Agency, Department of Health and US Food and Drug Administration (FDA), it added.
Fiona Dawson, a global president of Mars, said: "Our nutrition criteria sets a very high standard for our products, and we also want to help our consumers understand the difference between 'everyday' and 'occasional' products within a balanced diet.
"The food industry has already made great strides in reducing sodium, but we have more work to do to help consumers reduce sodium intake.
"We support release of the US FDA's draft sodium reduction guidance, because we believe it's important to begin a stakeholder dialogue about the role industry can play in this critical part of consumers' diets."
The move comes after Chancellor George Osborne announced a sugar tax, with the aim of tackling childhood obesity, in his recent Budget.


Jack Dorsey spends his mornings running one of the world's most influential social networks.

Then, at lunchtime, he springs up from his desk, walks a short way down Market Street, and takes charge of one of the world's biggest payment firms.
Just imagine that. Running both Twitter and Square must surely make Dorsey one of San Francisco's most under-pressure chief executives - an inbox chock-a-block with to-dos.
Many people said he wouldn't be able to do it. Indeed, when Dorsey returned last year to Twitter, a company he co-founded, it was only meant to be a temporary measure.
But eventually, the board came to the conclusion that if anyone was capable of reversing Twitter's fortunes, it was Jack Dorsey, even if they only had 50% of him.
It has been almost a year since he regained control of the company, and his most pressing problem back then still faces him today: fix Twitter.
"We're making progress," Dorsey told me, adding that he considers the most important thing to be the company's ability to devise, develop and release updates to the service.
"That's going very well, but you know, things take time to change."
Unfortunately for Twitter, the 300 million or so people who use the service at least once a month don't always take well to new ideas. One recent furore, for instance, was about an icon changing from a star to a heart.
And Dorsey's personal delivery of an announcement this week was designed to publicise that work was being done to make Twitter a simpler place to spend time on the internet.
But at the same time, he needed to stress that Twitter wouldn't be changing so much that its current, fiercely loyal users would feel alienated.
The "new" tweets, in which users can add photos and videos without using up any of the 140 character limit, seem to have found that delicate balance.
"We're not giving up on Twitter being in the moment," he said. "That concept of brevity, that concept of speed. Being able to just think of something and put it out to the world."
But improving simplicity isn't even half the battle for Dorsey.
Twitter, you will no doubt have noticed over the past couple of years, has become a service synonymous with online abuse.
That may be an unfair tag to load onto Twitter, but the ease in which people can sign up - coupled with a lack of a Facebook-style real name policy - means anonymous, hateful comments feel more commonplace here than elsewhere.
Whether a public figure or not, those caught in the middle of a controversy can find the speed and frequency of replies overwhelming, and for some, pretty terrifying.
"I don't think the negativity and the abuse and harassment is unique to Twitter," Dorsey says.
"I think it's an industry-wide, internet-wide issue that we all need to solve. And we did make it a priority for the company."
He went on to outline the company's tools for blocking and reporting abusive users.
But it's in this area that Twitter has many users unconvinced.
Those who have been at the receiving end of abuse wonder how it can be that, after 10 years, Twitter's engineers are yet to devise ways in which abuse can be proactively stopped from reaching those being targeted, rather than relying on reactive action.
One popular suggestion - giving users the ability to automatically ignore messages from accounts that have only just been registered - remains ignored, for the time being. Dorsey lists safety as a priority, but you could argue it should be the priority.
What Twitter does have going for it, of course, is that an awful lot of people would miss it were it to disappear.
Regardless of the looming threat from "cooler" networks like Snapchat and Instagram, Twitter for now remains the world's watercooler.
But how much is that worth? One easy way to alleviate the pressure on Dorsey and his team would be to sell-up. Predictably, names like Google and Facebook spring to mind.
Is Twitter for sale?
"We're focused on making Twitter amazing and making something people want to use every single day," says Dorsey, avoiding the word "no".
"We are an independent company and we're thriving and we want to continue to build that."
Even if Google came to him right now with its chequebook?
"We're focused on building our service."
Since 2014 Twitter's stock price has dropped from an all-time high of $69 (Â£47) to, at the time of writing, $14. It surely can't go much further south without someone making an offer he can't refuse.

Team Sky's Luke Rowe says he "could be out for up to a year" after breaking his right leg while white-water rafting on his brother's stag party in Prague.

The Welshman has had one operation and will have another this week after fracturing his tibia and fibula.
Rowe, 27, concedes his lay-off might be even longer than a year.
"It was a freak accident. It wasn't like I was swinging from the roof tops drunk, but there is only one person to blame," Rowe told BBC Wales Sport.
Rowe, Team Sky's road captain, broke a rib in a crash on the opening stage of this year's Tour de France but rode on to help Chris Froome win the title.
Rowe, who says he has no regrets about attending his brother's stag-do, jumped into a shallow section of water while rafting and landed on rocks.
I knew straight away how serious it was, it was excruciating pain and there are quite a few broken bones. It was a case of trying to get out of the water as quickly as possible and into an ambulance.
I've broken a fair few bones in my career but this was significantly worse than any of them. It was double the pain - add the pain of a few broken bones together.
I lifted my leg, but my foot stayed still, it was kind of hanging off, limp. The bone didn't break the skin, but it is pretty scary when you look down and see that when you are on the side of a riverbank.
It was a freak accident but it was a mistake. The water clearly wasn't deep enough to jump into, but hindsight is a beautiful thing. Other people were jumping with no problems, but I hit a rock.
I knew straight away the implications of what I had done and how long it would take to come back.
Rowe told Team Sky he was going on the stag-do and they flew a doctor out to Prague to immediately accompany him back to Cardiff for the first of what could be several surgeries.
The leg is in a bad way and recovery is a bit of an unknown at the moment. It will be a long road back but I won't back down and I want to get back to where I was.
Some people react to the operations and treatment really well but it is hard to predict a race, a point in the season or even a year when I will be able to come back.
I've been asking the doctors time and time again. When can I train? When can I walk? When can I get back on a bike?
The first questions I asked were for dates because you get impatient. But essentially the doctors are all telling me the same thing. We do know that operation by operation, scan by scan, it will get better. But the timescale? We just don't know that.
It's a moment in your career where your back is against the wall and you really need to roll your sleeves up. It's going to be a tough few months for me and it could be up to 9-12 months - that's realistic.
I have to live my life. I'll be on crutches at my brother's wedding in seven weeks' time and I don't think I will be spending much time on the dance floor."


Christian Burgess scored his third goal of the season to fire Portsmouth to a 1-0 win at home against League Two promotion rivals Luton.

Burgess' thumping header from Carl Baker's corner 14 minutes before half-time handed Pompey victory at a sold out Fratton Park.
The win would have been more commanding but for Gary Roberts missing a late penalty.
Gareth Evans and left-back Enda Stevens both went close to doubling Pompey's lead as the hosts dominated the first half.
Evans should have done better in the opening seconds of the second half when he failed to convert a free-header from Baker's cross.
Roberts passed up the chance to seal the points in stoppage-time when he blazed over from 12 yards after Noel Hunt had been fouled by Olly Lee.
The win completed a double for Pompey over Luton following their 3-1 triumph at Kenilworth Road.
The Hatters' misery was compounded as midfielder Cameron McGeehan was taken to hospital after sustaining a 16th-minute injury in a challenge with Pompey captain Michael Doyle.

A homeless woman who died in Belfast city centre at the weekend has been described as "an amazing" person.

Thirty-two-year-old Catherine Kenny was found dead in a shop doorway at the corner of Donegall Place and Castle Lane on Saturday morning.
Her sister, Lee-Marie Hughes, told the BBC that Catherine's death left her feeling "devastated" and "heartbroken".
Police are investigating the cause of her death but a crime is not suspected.
Catherine Kenny is the fifth person to die in Belfast this year who had been receiving help from homeless charities.
Ms Hughes described her sister as a caring person who, "would have helped the lowest in society".
She also spoke of how drugs had a significant impact on Catherine's life.
"We had a very intense and long battle with Catherine and her addiction to alcohol and drugs," she told the Stephen Nolan show.
"We've been dealing with this since Catherine was 16, but, back then, it was never hard drugs. But then they gripped her with a vengeance."
Mrs Hughes husband, Darren, said Catherine had tried on numerous occasions to turn her life around.
"Catherine got to a dark place and unfortunately tried many times to come back on the path again but wasn't able to.
"I firmly believe that a  lot of that was from not being able to avail of residential detox and addictions care.
"She kind of just moved around to try and start somewhere afresh - a fresh start would be a fresh outlook on life, but unfortunately the demons just followed her".
The Extern charity said it had worked with Ms Kenny and had offered her emergency accommodation.
Danny McQuillan, a direct with Extern, said it was a "complete tragedy that once again another homeless person has died on our streets".
"Nobody should be living and certainly nobody should be dying on our streets in 2016," he said.
Ms Kenny was found by a passerby who knew her.
James Edwards told the BBC: "I walked past her and I noticed her sleeping bag wasn't wrapped around her."
He noticed that something was wrong when he tried to cover her with the sleeping bag, and the emergency services were called to the scene.
"She was a really, really nice girl and she didn't have a bad bone in her body," Mr Edwards said.
"It's just an awful shame - this girl could have had help."
Last month, the lord mayor of Belfast held an emergency meeting of agencies that work with the homeless following the death of a man in a shop doorway in High Street on 24 February.


A wedding venue in the Vale of Glamorgan has been fined £20,000 after a guest tripped, broke his neck and died because its patio lights were not working.

Grandfather Bob Kemp, 62, from Barry, stumbled over a low wall in the darkness at Sully Sports and Leisure Club in June 2012.
Newport Crown Court heard he fell just 4ft (1.2m) onto the grass below.
He was taken to the University Hospital of Wales, Cardiff, but never recovered.
Judge Ian Murphy QC said: "Mr Kemp was in perfectly good health, he was a healthy and happy man when he came out of that club.
"But he had been exposed to an unnatural risk to health."
The court heard, on the evening of the tragedy, the lights placed above the wall had not been working properly.
Alex Greenwood, prosecuting, said: "The club paid only lip service to health and safety issues."
But Sully Sports and Leisure Club claimed they had a "common sense" approach and denied any wrong doing.
However, the jury found it guilty of breaking health and safety laws after failing to provide adequate lighting.
The court also heard Mr Kemp's partner of almost 30 years, Jenny Newland, died a few months later.


What is thought to be the last surviving Dundee tram has been found in a garden in Perth where it was being used as a summer house.

The horse-powered Dundee Corporation tram dates from the late 19th Century and is believed to be one of the first built for the city in 1887.
It has now been removed and taken to Dundee Transport Museum to be restored and added to the collection.
The museum already has the last surviving Aberdeen tram.
The Dundee tram was removed from service to be replaced by electric vehicles shortly after the turn of the century.
Almost all the old trams were burned, but the number 24, which ran a route through Dundee city centre in to the west end, survived.
It was transported to Perth where it was placed in the garden of a man called Jock Ness.
Jimmy McDonnell, chairman of Dundee Museum of Transport, said: "It's one of the first built for Dundee and is almost certainly the last of its type to survive - and it's one of the oldest surviving in Scotland.
"It has now lain in that garden for a long period of time - we can account for at least 60 years, but we believe it has been there for up to 100.
"It has been used as a summer house, but it still has its original interior which is astounding."
"When we found it in situ it was just about landlocked - the houses and an orchard have grown up around it."
Mr McDonnell and a team of volunteers, including heavy moving experts, worked to lift the tram and transport it to Dundee.
He added: "It weighed two tons and we had to lay a plastic road and get it on to a low loader with special lifting plant.
"We have people coming up from the British National Tram Museum to take a look at it because they are very interested in it.
"It will take pride of place in our museum when it is restored."
