Labour won the Wythenshawe and Sale East parliamentary by-election today while the Conservatives were pushed into third place by Ukip and Lib Dem support was decimated.
Former councillor Mike Kane held the seat for the party, polling 13,261 votes.
Ukip surged from fifth place in 2010 to second despite leader Nigel Farage complaining the campaign had been "as dirty as they come".
The party's success and the demise of the Tory vote is yet another by-election blow to Prime Minister David Cameron.
But the Liberal Democrats were dealt a humiliating blow when they polled just 1,176 votes - not enough to hold their deposit.
The by-election was brought about by the sudden death of the serving MP, Paul Goggins, on January 7, at 60.
