Mr Corbyn threatened to call the vote if Mrs May refused to name a date for Parliament to debate her Brexit deal – only to change his mind after she did set a timetable.

Last night the PM called the Labour leader’s bluff saying she’d give time for a Commons debate – on the condition it was for full confidence of her Government and not her leadership.
