Counting is under way in the Glasgow North East Westminster by-election, amid predictions of a Labour victory.
Labour has won the Glasgow North East by-election, sparked by Michael Martin's resignation as Commons Speaker in the wake of the MP expenses scandal.
The contest was sparked after former Commons Speaker Michael Martin stood down over the MPs' expenses scandal.
Willie Bain won for the party, while the SNP came second after failing to break through in what has been safe Labour territory for the last 74 years.
SNP deputy leader Nicola Sturgeon said she expected Labour candidate Willie Bain to hold the seat comfortably.
The Tories came third, leaving the British National Party in fourth place. Left-wing Solidarity came fifth.
Voter turnout has been confirmed as 33.2%. It has also emerged that police are investigating two alleged incidents of voting fraud in the contest.
Voter turnout, at 33.2%, was a record low for a Scottish by-election.
Turnout is the lowest of any Westminster by-election in Scotland.
Meanwhile, police were called in to probe reports of voting fraud.
It has been predicted the British National Party will take third place.
Labour has been the main political force in the area for the last 74 years, with Mr Martin - now Lord Martin - holding the seat in the 2005 General Election with a 10,134 vote majority.
Brian TaylorPolitical editor Big question for the SNP is why the seat is so different from Glasgow East, which they won in the summer of 2008.
Party strategists say the big difference is that, in east, they were able to corral aspirational voters and persuade them things could and should be better.
Faced with the hopelessness witnessed in Glasgow North East, that was a much tougher task.
The constituency neighbours the Glasgow East seat - which the Nationalists snatched from Labour last year in a stunning by-election victory.
Nicola Sturgeon, the SNP's deputy leader, conceded that her party seemed to have failed to repeat that result.
She said: "I'm not predicting an SNP victory, I think Labour will hold the seat comfortably.
"This was very difficult territory for the SNP. In Glasgow North East the SNP don't have the same political base."
Scottish Secretary Jim Murphy said it was possible his party could pick up more than half of all votes cast.
"Things have gone well in terms of the Labour campaign," he said.
"Gordon Brown visited the constituency, he didn't visit Glasgow East, there's a real appreciation across Glasgow about the way Gordon Brown has handled this recession."
Prof John Curtice, of Strathclyde University, also told the BBC he expected Labour to win "fairly comfortably".
'No tradition'
BNP candidate Charlie Baillie predicted the best result ever for his party in Scotland.
He said: "I confidently predict that we shall easily save our deposit and possibly more.
"We have been out campaigning ceaselessly for three or four weeks, the literature we've put out and the effort the team have put in has been absolutely meteoric."
Scottish Conservative deputy leader Murdo Fraser told the BBC this was a seat where his party was often on the brink of losing its deposit.
"There's no tradition of people voting Tory here in a Westminster election," he said.
But he praised Tory candidate Ruth Davidson for fighting a "very energetic" campaign.
Liberal Democrat Westminster leader Alistair Carmichael, said: "We've always found it more difficult, particularly in the west central belt of Scotland.
"Not least because we're in a different political landscape here, and there is another obvious repository for protest votes in Scotland and that's the SNP."
'Alleged personation'
It has emerged that three ballot papers were taken away by officers from Strathclyde Police.
Council chiefs said the investigation involved two ballots cast at a polling station in the Dennistoun area and another cast at another polling station in the same area.
A council spokesman said: "We had two incidents at polling stations where voters turned up and when they identified themselves they were told their names had already been scored off the list - somebody had been given a vote in their name."
"We checked our processes to ensure it wasn't a mistake, it wasn't as far as we can see, so we called in the police.
"Police are still investigating alleged personation."
There are a total of 62,475 eligible voters in Glasgow North East, which saw a voter turnout of 45.8% in 2005.
