I can't disagree with the critiscism levelled at the Prime Minister but the fact of her being bad does not make Jeremy Corbyn good. Immeadiately after the meaningful vote he said that Labour's position was clear. If the Labour Party have a clear policy on Brexit then I better look under the sofa and see if I can find it.
Both May's and Corbyn's styles are similar:- say as little of substance as you can get away with in the hope that you won't get the blame in the future and, once you have found a phrase that seems to work, repeat it as a mantra. I'm sure that Theresa May has tried her best and that Jeremy Corbyn is a man of principle but neither of them are strong leaders.
