I don't think JC has the Parliamentary Labour Party backing. My own Labour MP wont even mention his name or place it in her election literature (something that's gone on a lot with the others as well). Its interesting we could get a new PM of either hue with a lot of back stabbers right behind them right from the off.
But I would venture yes whatever's left will be binned and the money whatever money spent elsewhere. Spun out with new jobs for the ex service leavers in say the police, or border control.
