BREXIT SHOCK: May’s deal will threaten NATIONAL SECURITY, ex-defence chiefs warn

Two senior former security chiefs condemned Theresa May’s Brexit deal as a threat to national security today and called on Tory MPs to vote it down.

Ex-MI6 boss Sir Richard Dearlove and former head of the Armed Force Lord Charles Guthrie together wrote to local Tory party chairmen urging to pressure their MPs to vote no.

The letter is a fresh blow to Mrs May’s desperate attempts to win on Tuesday night with forecasts suggesting she is on the brink of the biggest ever Commons loss.

Protecting national security has been a key argument of the Prime Minister in defence of her deal – insisting cooperation with the EU is crucial for protecting UK citizens.
