CONSERVATIVE MP Nigel Evans has warned the Prime Minister that if she fails to deliver a swift departure from the European Union she must quit.

The Ribble Valley Brexit campaigner said a long delay in leaving would be 'totally unacceptable'.

Mr Evans, who last week reversed his previous Commons vote and backed Theresa May's Brexit deal, said: "She had promised, as Prime Minister, to deliver what 17.4 million 'Leave' supporters voted for in 2016."

He told the BBC yesterday: "That is what she has to deliver and if she can't do that she has to go."

Mr Evans said delaying leaving the EU, originally scheduled for March 29, beyond June 30 would be betrayal of the result and a failure of Mrs May's authority.

He appealed to pro-Brexit Tories to back her deal to secure departure from the EU and said voters were in 'despair' over MPs failure to agree on the issue.

Mr Evans said he was now 'frightened about being trapped in the EU'.

Blackburn MP Kate Hollern said if Mrs May could not secure a 'well-managed Brexit', she should call a general election.
