Sue Hayman has been re-elected as MP for Workington.
The Labour candidate won with 21,317 votes against Conservative Clark Vasey, with 17,392 votes, Ukip's George Kemp, with 1,556 votes, Lib Dem Phill Roberts, with 1,113 votes and Independent Roy Ivinson, with 278 votes.
Mrs Hayman said: "Thank to all the people in Workington who put their trust in me to be their MP and continue with the work I've been doing.
"We've fought this campaign on a positive message of standing up for people, defending our NHS, police, school, public services and getting the best possible deal for Brexit."
She added it was disappointing that the Conservatives had decided to fight such a negative campaign.
Mrs Hayman said: "I will pledge to continue to work tirelessly for everyone in the constituency, no matter how they voted.
"It's a great honour to be re-elected as your MP."
Mrs Hayman thanked council staff, police and the returning officer Andrew Seekings for their help during the count.
She also thanked her agent Celia Tibble and her campaign team for their hard work.
The turnout in Workington was 69.25 per cent with a postal vote turnout of 84.16 per cent.
Mr Vasey entered Workington Leisure Centre, where the count was held, to hear the results being announced and left the venue straight after.
All losing candidates declined to give a speech following the announcement of the results.
Mrs Hayman, who was elected for the first time in 2015, received 5,035 more votes than the previous election, but her majority decreased from 4,686 to 3,925.
During the count, Mr Kemp, Mr Ivinson and Mr Roberts said they knew they did not have a chance of winning the seat.
Mr Kemp said: "A lot of Ukip votes have gone to the Conservatives, especially to try and win the seat for the constituency.
"A lot of my local voters said they would be voting Conservative because they don't like the idea of Jeremy Corbyn in the Government.
"Ukip has seen a bit of a decline since Brexit."
Mr Ivinson stood in the Workington constituency for the first time in 2015 and stood in the Copeland by-election earlier this year.
He said he learnt a lot from standing three times in two years and he was enjoying the buzz of the count.
Mr Roberts said: "The Liberal Democrats' campaign went as we planned. We were able to get our major policies out to the electorate.
"At the same time we addressed Theresa May's attempt to crush the opposition in Parliament which we felt was totally undemocratic. The electorate have now realised that."
On the national results, Mrs Hayman said: "I'll be going home and watch it unfold. It will be an interesting evening."
