Top Tory George Osborne has already congratulated John Stevenson for his victory in Carlisle.
Count has started at Barrow Town Hall.
Carlisle was expected to be Cumbria's closest contest. A victory with a 2,774 majority - for either side - was never predicted. Battle between Tories and Labour has mirrored national campaigning from start to end.
Justice Minister Simon Hughes has lost his seat Bermondsey. Labour steal with 4,489 majority.
Alex Salmond has just won his seat

Conservative David Mundell, the only Tory MP in Scotland in the last parliament, says the outcome of the contest with the SNP in Dumfriesshire, Clydesdale and Tweeddale is "too close to call".
First non-SNP MP in Scotland is Lib Dem Scottish Secretary Alistair Carmichael, who has retained his Orkney and Shetland constituency, but his support fell from 62% in 2010 to 41.4% this time.
Tory Mayor of London Boris Johnson is back in Parliament as MP for Uxbridge. Will Parliament be a more colourful place with him it?
Vince Cable, Business Secretary in the last government, has lost his seat in Twickenham. Another big casualty.
Labour politician Thomas Docherty, son of the late former Copeland councillor Bob Docherty, has lost his seat in Dunfermline to the SNP.
Lib Dem leader Nick Clegg has retained his seat in Sheffield, but with a much-reduced majority.
Candidates in Workington appear to be getting closer to the stage....could we be near a declaration?
Nick Clegg says it's been a "cruel and punishing" night for his party - further fuelling talk that his time as leader is over. Pundits still have Cumbrian MP Tim Farron as the front-runner.
David Mundell has HELD Dumfriesshire, Clydesdale and Tweeddale for the Conservatives. A fairly safe bet that he'll be Scotland's only Tory again in the next Parliament.
Currently unconfirmed, but it is widely believed that Labour's Ed Balls has lost his seat. He was recently in Carlisle to back Lee Sherriff in her bid for the Carlisle seat.
Another high-profile casualty as Esther McVey, employment minister in last Cons govt, loses her seat.
In Dumfriesshire, which covers places including Gretna, Annan and Langholm, David Mundell polled 20,759 votes, just 798 ahead of the SNP's Emma Harper.
