TG, Mr Corbyn practically invites the criticisms levelled at him.
eg this week's Julie Etchingham interview. he could have just said (about the queen's broadcast) "nah I don't watch it" and the thread would have ended. Instead he claimed to have watched it at a time that was provably impossible.
some years ago the labour party had an issue with the international definition of anti Semitism, due, it's said, because of issues around the criticism of the state of Israel. if that was the case, Mr Corbyn should have said, assertively, "we're not signing this, and this is why....". Instead he sat on his hands and said nothing, causing the party to be backed into a corner, forcing a signature to something they had issue with and not helping with the overall Judaism situation the party are now in.
the man is at best a liability. at worst, well you decide.
