“It is absolutely clear to me it is because of my support for Corbyn.”The post they are referring to was put up over a year ago so it is extraordinary to use it now.”Someone has got paranoid and thought I am describing the Labour bureaucracy as fascist. They are making a big mistake.”I would never describe the Labour Party as fascist.” The great-nephew of former Prime Minister Clement Attlee has been suspended from the Labour Party after he posted a picture on social media of David Cameron with a Hitler moustache.John Macdonald, a longtime Labour member who supports Jeremy Corbyn for the leadership, uploaded the image of Mr Cameron in August 2015.Superimposed on the picture was a quotation from Mein Kampf, in which Hitler outlines how to take total control by taking “a little of their freedom at a time…until past the point at which these changes cannot be reversed”.Mr Macdonald’s suspension, which occurred last Friday, came immediately after he publicly backed Mr Corbyn’s latest campaign.
