No.
Smaller parties Liberal Democrats, SNP, would immediately reverse the decision if given power.
The referendum is irrelevant to them.
Labour would play the same games, even though the leader, Jeremy Corbyn, would secretly like to leave.
But the majority of Labour MPs and party members want to stay in the EU.
Or, at a minimum, go from being 'half in' the EU, to being 'half out' of the EU.
Lib Dems won't get into power, unless it's part of a coalition like the one they had with the Tories between 2010 and 2015. SNP won't get to power - they have no mandate outside of Scotland.
Labour, led by Jeremy Corbyn, a Leaver, are a Brexit party, but I would rather have Davis, Fox and Johnson negotiating Brexit deals than Starmer, Gardiner and Thornberry, which would be our Brexit team should Labour get in soon.
