Based on some of the changes he signalled this week, I think that is what he will do. I think the plan will be to build up support in the opinion polls over the winter, then test the water with the local elections in May. If that looks ok, I think he will go for an election in early July, which will be 3 years since the last one. That's not too unusual really, because most governments try to go the country after 4 years anyway (they only ever go the full 5 year term if they are behind). Jim Callaghan and Gordon Brown got the timing wrong. As you say, I think he wants to get on with the changes, so beginning them sooner is in his own interests.
