Having called a snap election Theresa May's campaign goes from bad to worse. First she hid from the public and then there were a couple of disastrous tv appearances. Then the debacle of the Tory Manifesto and the Dementia Tax. And then Jeremy Corbyn who May started the campaign holding a 24 point lead over, catches the whole of the political right and their croney media out by suddenly announcing he will take part in the leaders debate, which May has repeatedly refused to consider joining.
