TEN years at the Town Hall, Theo Blackwell has told colleagues that he will turn the Labour Party’s annual general meeting into a leadership contest rather than a coronation. Sarah Hayward had been the only candidate to have officially thrown her hat into the ring ahead of next month’s meet-up. Her notice that she would challenge leader Nash Ali led to Nash step down two days later. Theo had always said he would think about whether he would make his own pitch. He has now done so in a series of messages to colleagues this week, which I’m told include a fond tribute to Nash and some ideas for the way forward.
