Mark Hendrick was returned to Westminster as Preston’s MP after a landslide victory at the Guild Hall.
The Labour politician secured 18,755 votes - increasing his previous majority by more than 50 per cent.
His majority was increased to 12,067, with Conservative candidate Richard Holden polling 6,688 votes.
UKIP’s James Barker took third place with 5,139 votes, while Gemma Christie of the Green Party won 1,643 votes.
Liberal Democrat candidate Jo Barton received 1,244 votes.
Mr Hendrick’s majority in 2010 was 7,733, which was increased by more than half at this year’s election.
After the result was announced by Mayor of Preston, Coun Nick Pomfret, Mr Hendrick said: “It is an excellent result - it’s a 50 per cent increase on last time.
“I’m delighted for myself, but a bit deflated about what seems to be happening elsewhere in the country so I have mixed feelings.
“I think Lancashire’s results look excellent, but obviously with Scotland, and winning less than we expected elsewhere in the country, means I have lost a lot of very good friends and colleagues and I am sad to lose so many.
“I think we are looking towards another five years of austerity and things are going to get very difficult and in some cases worse for people in Preston.”
