The Isles of Scilly's MP has suggested that the success of the Brexit Party in the European elections was in a part a protest vote.
Derek Thomas, the Conservative MP for the St Ives constituency, said that tomorrow’s by-election in Peterborough will be the real test of what people may do in a general election.
He told Radio Scilly that he hopes the Tories will win back the seat they lost to Labour in 2017 and that he believes a change in leader will help the party’s chances.
"I think the real test of how people are feeling will be this Thursday. What I hear when I’m out and about is that people expected us to have done Brexit by now and they are not necessarily holding the political party to account, they’re holding Theresa May. And it may be that a change of leader might change people’s outlook on how they vote in the future."
Derek added that there is a danger of the two-party system collapsing if Brexit is not delivered.
He said: "In 2017, people voted for Labour and Conservatives in massive numbers. 85% of MPs are in those two parties in Parliament. Every single one of us stood in a manifesto to deliver Brexit and I think what you’ve got now is a complete disappointment and breakdown of trust because people voted for something in 2017 which we haven’t done.
"So I think we’ve got to get Brexit done. If we don’t deliver Brexit for any reason I think you will then see a real break-up of the main parties."
