Theresa May will have put Brexit in "jeopardy" if she fails to win the election, it has been claimed.

Paul Nuttall, the Ukip leader, branded the decision to call a snap election "hubris" and said it would have far reaching consequences if the exit poll proves correct.

Early predictions suggested that the Tories would fail to win a majority, resulting in a hung parliament.

"If the exit poll is true then Theresa May has put Brexit in jeopardy," Mr Nuttall tweeted.

"I said at the start this election was wrong. Hubris."

Brexit talks are due to begin later this month but if Labour win, they have vowed to scrap the Brexit white paper and replace it with a new list of negotiation priorities.
