With this new plan for introducing National Service, looking at raiding funds that are for levelling up in the North, and previously saying he wouldn't want to be a war time PM. Could it be he thinks we may be dragged into something in the upcoming years, and wants out before he has to look cowardly, so is doing what he can to purposefully lose the election?
The sceptic in me says it makes no sense to come up with such a contentious and unpopular proposal this close to an election.
