Labour leader Ed Miliband has called the loss of a 6,000 vote majority in the Bradford West by-election "incredibly disappointing".
George Galloway and his Respect Party won by 10,000 votes, taking a seat Labour have held since 1974.
Mr Miliband said it was important to learn from the defeat, including why "only four out of ten people voted for the three mainstream political parties."
