Shadow chancellor John McDonnell gives us the first reaction from a Labour figure. He says if the result is anywhere near the exit poll it "will be extremely disappointing for the party overall and the movement".
He admits it has "come as a shock" and he "thought it would be closer".
Mr McDonnell says: "We knew it would be tough because Brexit has dominated."
But he adds he hoped "other issues would cut through".
He is pressed on whether he and Jeremy Corbyn will resign, but he says: "We will see the results in the morning and decisions will be made then."
