Labour's Clive Lewis said his party should have been clearer on Brexit, after an exit poll predicted a major defeat for his party.
Mr Lewis, who is defending his Norwich South constituency, is a strong remainer but Labour pledged to negotiate a new Brexit deal if they got elected.
The Broadcasters' Exit Poll at 10pm on Thursday, 12 December predicted an 86 seat majority for the Conservatives.

Reacting to that, Mr Lewis said party leader Jeremy Corbyn should have been clearer.
He said: "I genuinely think sometimes in politics you have to pick a side and fight for it.
"On the biggest issue in British politics since the Second World War, we have spent two years triangulating.
"You’ve kind of squandered it and I think that ultimately that is one of the key issues here."
Mr Lewis said he'd wait to comment on Mr Corbyn's future as Labour leader until all the results were in, but there is already speculation he could resign.
