That Slogan, about Labour siding with the EU, is yet another HUGE lie in a litany of lies. The Labour Party is siding with the good name of the British people. Upholding international law.
By creating a false slogan, writing in big letters that this is Labour actually siding with the (nasty, emotive) EU, the Conservatives hope that enough people will jump to the conclusion that Tories = Backing Britain. Labour = Backing the EU... when it is absolutely f*** all to do with it. Truth is, loads of people don't really understand/care that much, and just see the headlines.
This tactic, whoever plays it (but it is predominantly people like Johnson, Cummings and Trump) ... it is a sickener for public debate and democracy. So... not really funny. No.
Well I thought it was funny.... much like most of the rest of politics.. Surely you don't take these bent,lying charlatans seriously? You must be very young if you do.
