The predicted 55 seats for SNP would be a “great night” for the party according to its Dunfermline and West Fife candidate.
Douglas Chapman, who is expected to hold his seat, said he was confident of success in his constituency based on canvassing but it remained too early to judge the result.
Mr Chapman won with a majority of just 844 in the 2017 general election and again faces competition from Labour’s Cara Hilton, who was hot on his heels then.
Exit polls have suggested that SNP will increase its seats in Westminster and that Mr Chapman and party colleagues in North East Fife and Glenrothes, Stephen Gethins and Peter Grant, will hold theirs.
Mr Chapman said: “Certainly, the exit poll looks good, although I think it comes with a very large health warning.
“As the night unfolds we will need to see how close the exit polls are to reality, but certainly if we could end the election now with SNP winning 55 seats I would take that as a great night for the SNP.”
Speaking at the Michael Woods Sports and Leisure Centre, in Glenrothes, where votes from Fife’s four constituencies are being counted, he said that from conversations on doorsteps, signs were good for him.
However, he said he had been “in this game far too long” to make any assessment based on the first ballot boxes.
“Hopefully, if the reaction we have been getting at the polling stations today is anything to go by it’s very positive, so let’s hope we can push that into actual votes by the end of the night,” he said.
Mr Chapman also said turnout at polling stations looked very high, up on 2017 figures.
He said: “That’s a good sign for democracy that people are prepared to go out and cast their vote.
“Some of the conversations we have had on the doorstep have been really quite intense, not in an argumentative way, but I think people have been really struggling with understanding what’s going on and how they should cast their vote in the best direction.
“It’s not been an easy decision for a lot of people but I’m hopeful they have decided in the right way as far as we are concerned.”
Standing for the Liberal Democrats in Dunfermline and West Fife is Rebecca Bell and for Conservative Moira Benny. Mags Hall is the Scottish Greens candidate.
Voter turnout is yet to be announced. Last year’s turnout in the constituency was 67.5%
