The Camborne and Redruth MP George Eustice has criticised the Prime Minister's handling of Brexit negotiations, saying she should have reached out to other parties to build a consensus behind a plan.
The former minister quit the Government earlier this year because of Brexit.
Mr Eustice said despite the fact she had shown 'tenacity and resilience', she had "lacked agility" when it came to negotiations.
He added that Theresa May had been sent to Brussels on "her hands and knees to beg for an extension", and claimed the European Union had also "not acted in good faith".
Mr Eustice was speaking as part of the West Country Debate - where he was joined by Bristol East MP for Labour Kerry McCarthy, and Bath's MP Wera Hobhouse for the Lib Dems.
The pair heavily criticised Theresa May's speech where the Prime Minister laid blame for a delayed Brexit squarely at MP's feet.
