It’s temporary, but the caretaker PM gets to stay in office throughout the election campaign. My guess is that if Corbyn could demonstrate that he has the votes the Lib Dem’s would come on board. But it seems very unlikely that enough Tories would be able to stomach having Corbyn in charge of national security even if its only for a couple of monthsIt’s a temporary measure and then they’ll have a general election, I cannot fathom why they can’t just put party politics behind them and get it done.
