Sammy Wilson cruised to a comfortable victory in East Antrim on a disappointing night for the Traditional Unionist Voice (TUV).
Despite losing almost 2,000 votes from his 2005 Westminster triumph the former economics teacher and DUP Finance Minister was in ebullient form as he promised no return to the violence of the past.
He received 13,993 ballots and said the election showed the public wanted positive action from their representatives.
"I believe that the results which we have seen across Northern Ireland over the election have indicated that people in Northern Ireland want one thing and that is they want to see politicians doing positive things to make their lives and their communities better," he said.
"They don't want to go back to the 1970s or the 1980s, they don't want just as we have seen at Foyle, the security situation many of us have lived through for all of our lives, happening again in Northern Ireland."
The TUV's Sammy Morrison trailed in last, with 1,826 votes, and made no excuses but congratulated the victor.
The Conservatives and Unionists' Rodney McCune, a barrister in London who gained 7,223 votes, was less charitable.
"It is a good result, we have done incredibly well. We have got an MP who has been here for five years, who has had a decrease in his majority which is very unusual in a first term for any MP," he said.
"We look forward to seeing what status the incumbent has the next time we have an election."
Mr Wilson served as Environment Minister at Stormont where he sparked controversy with his denial of climate change.
He is known for his feisty opposition to Labour and the Conservatives and Gerry Lynch, defeated Alliance candidate, said the message on the doorsteps had been that he was a good MP.
