Reaction to the result in the Glenrothes Westminster by-election which saw Labour hold the seat.
LINDSAY ROY - SUCCESSFUL LABOUR CANDIDATE
"This is a victory for the people of Fife, it's a victory for Gordon Brown, it's a victory for the Labour Party.
"It's a victory for our team of staff in the Labour team who have taken on a tremendous challenge here and done so effectively well."
ALEX SALMOND - FIRST MINISTER AND SNP LEADER
"Obviously, we are disappointed not to take what was a safe Labour seat.
"However, we substantially cut Labour's majority and achieved a 13% increase in our share of the vote and a 5% swing against an entirely negative campaign on local issues from the Labour Party."
TAVISH SCOTT - SCOTTISH LIB DEM LEADER
"The first minister made a great virtue of visiting Glenrothes regularly.
"Perhaps if he spent more time being first minister rather than leader of the SNP, there would have been a different result."
PETER GRANT - SNP CANDIDATE
"We have seen the SNP vote in this constituency increase by almost 50% on what it was a few years ago.
"That is a magnificent result by any standards, without taking anything away from the achievement Labour have managed."
MAURICE GOLDEN - CONSERVATIVE CANDIDATE
"The Alex Salmond bubble has well and truly burst. Scotland has woken up to the fact that in a Westminster election, the SNP is not a voice for change."
ANGUS ROBERTSON - SNP LEADER AT WESTMINSTER
"Let's deal with the facts. The SNP vote in the last Westminster general election was just over 8,000 and last night it was just over 13,000 so another 5,000 people left their homes and voted for the SNP.
"Our vote went up - that's a good thing - it wasn't enough to win the seat, Labour's majority went down."
DAVID MUNDELL - SHADOW SCOTTISH SECRETARY
"This was an election which was fought on very local issues, very Scottish issues.
"It's not an election which can be extrapolated into a UK general election."
GORDON BANKS - LABOUR BY-ELECTION CAMPAIGN MANAGER
"We have put under scrutiny the SNP at local, national and devolved level and they have been found wanting."
