Rachel Reeves held the Leeds West seat for Labour with an increased majority of more than 10,000.
Speaking after the declaration, Ms Reeves conceded it was a disappointing night for her party, but was still proud to represent her constituency.
“I would like to think everybody in Leeds West who have had put their faith and trust in me. It was an honour to be elected five years ago, and I will work as hard as I possibly can to fulfil that honour again.”
“Tonight has been a difficult night for my party. We will have to learn from and understand the result.
“I am sorry that the manifesto that I fought for will not be implemented, but I am also sorry for the people of Leeds West and the people of my country that we can’t fulfil it.”
She also refused to be drawn on whether she feels Ed Miliband is the right man to lead the Labour Party.
“I don’t think that is a decision for here and now,” she said, “We don’t yet have all the results from the other constituencies.
“I am proud to serve Leeds west and will continue to do my best for the constituents.”
The result was announced with Ms Reeves receiving 18,456 votes, powering ahead of nearest challenger, Conservative Alex Pierre Traves, on 7,729.
The first ballot boxes arrived at just after 11.30pm, to a frenzy of sampling from officials.
At one point officials and candidates were warned against placing papers on the counting tables.
The seat has been a Labour stronghold since 1987 when John Battle took the seat from Liberal Michael Meadowcroft.
Rachael Reeves has held the seat for Labour since Battle retired in 2010, when she received 16,389 votes.
