Former defence secretary Gavin Williamson has launched attacks at Prime Minister Theresa May as he described her Brexit talks with Labour as a 'grave mistake'.
Mr Williamson, who was sacked over the Huawei leak, said pressing ahead with the talks will have 'fatal' consequences and pointed that Labour Party leader Jeremy Corbyn's goal is to bring a general election.
He labelled Mrs May as 'politically naive' for going into fruitless negotiations with Labour and urged her to 'make the right choice', he told the Mail on Sunday.
The Tory for South Staffordshire said: "Even if Labour do a deal, break bread with the Prime Minister and announce that both parties have reached an agreement, it can only ever end in tears.
"The Labour Party does not exist to help the Conservative Party.
" Jeremy Corbyn will do all he can to divide, disrupt and frustrate the Conservatives in the hope of bringing down the Government.
"His goal, and he has made no secret of it, is to bring about a general election."

Mr Williamson said Mrs May seemed oblivious to the fact many Tories believe she is 'negotiating with the enemy'.
He added: ""Even if we get to a point where Jeremy Corbyn agrees a deal with the Prime Minister, when it comes to detailed scrutiny of the votes, Labour will revert to form.
"Even if it passes the first few votes, it will fail later."
he former Cabinet minister believed the Prime Minister failed to 'recognise when a plan will not work' as he warned her that she was turning her own supporters against her.
"We are now at a crossroads and it is imperative the Prime Minister makes the right choice," he added.
"In order to deliver Brexit, there has to be a clear-sighted determination of what you are wanting to deliver, as opposed to delivering the lowest common denominator.
"The only way to deliver anything is by ensuring you have your own tribe and your own people with you 100 per cent of the way.
"This is what has to be delivered - not doing a deal with Labour."
The European Union and the UK have now agreed to postpone the Brexit deadline to October 31 after the MPs failed to reach an agreement to move forward.
