Half of Leave voters feel “betrayed” by Boris Johnson’s failure to take Britain out of the EU today, leaving the Tories at risk of haemorrhaging seats to Nigel Farage’s Brexit party, according to a new poll.

A survey carried out by a former Downing Street pollster reveals 57 per cent of Leavers are “disappointed” at the deadline being moved to January, 22 per cent are upset and just 2 per cent are pleased.

However, more worrying for the Tories is the revelation that of those who voted for Brexit, 49 per cent feel “betrayed” at missing the October 31 deadline which the PM vowed to meet “do or die”, adding that he would “rather be dead in a ditch” than get an extension.
