Labour are going to get a massive kicking at the next election, Corbyn has been a massive anti-EU campaigner all his career, wanting to take back power off the EU.
He's a charlatan, with Keir starmer in his ear a staunch remainer, he's been told this is how you fight the Tories to win, so he's changed Labour into a remain party, turned his back on thousands of supporters who voted leave, and done a 180 on his own beliefs in order to try be PM.
Sooner Corbyn is gone the sooner Labour can genuinely think about winning an election again, when Starmer will probably be the next leader.
