Quite the contrary. Europe was the issue that split the Tories down the middle. Cameron made a huge strategic blunder in allowing a referendum in order to silence the anti-EU faction. Many Tory politicans, Boris Johnson being the most high-profile, split with the leadership and campagined for Brexit. Labour MPs on the other hand followed the party line like drones even though, ironically, it's well known that the current not-for-much-longer leader, Jeremy Corbyn, is a joke Marxist who's anti-EU himself.
At the next election Brexiters wont have a problem voting Tory. With any luck Scotland will have fucked off too by then. The only way Labour can recover is to have a huge cull at the top and elect a new leader who isn't tainted by their Brexit failure. There is a formidable leader-in-waiting in Dan Jarvis who would be a very difficult opponent for the Tories as he's a straight-talking ex-military guy who served in the Paras (Parachute Regiment). Jarvis's weakness is supposed to be his his lack of intellect ... he can't remember foreign presidents' funny names or comment on the economy but, suitably coached, that might not be a fatal handicap.
