Your scenario doesn't include the (unlikely, but delicious) possibility of the Conservatives tearing themselves asunder in the process, nor does it include the (slightly more likely) possibility of former Tories leaving UKIP and returning to the nest, creating further tension and conflict within. The Tories may win any new election, but they won't be able to catch a break Europe-wise (if Remain wins).In this case, there would be some shenanigans for sure. I expect the Conservatives would engineer a no-confidence vote against their own government, leaving Corbyn with the impossible decision between (a) facing a General Election in which he will be absolutely tonked and (b) having to propose a vote of confidence in a Conservative government in order to avoid (a) ... and then him being expelled from his own Labour Party because of doing (b).
Or some similar permutation.
Let me dream, even if only for a moment.
As far as I know, content claiming on Youtube is automatic, so I doubt the BBC had anything to do with it (as in, any actual intent).It just seems to be people laughing at Mensch again.
