Go on then, I'll ask a naive question, and please don't assume anything about my politics from this question - I don't like any of the parties in their current incarnation.
When Mr Corbyn says he'd do ANYTHING to avoid a no-deal Brexit, I presume he means he'd do anything APART from vote for the deal already agreed with the EU? Seems a very limited definition of "anything".
TBH I don't take Mr Corbyn's position on anything particularly seriously. His main priority appears to be for Brexit to happen but for someone else to get blamed for it. A tactic which doesn't seem like it has a remote chance of working.
