Their stance on Brexit is kinda theoretical - they'd cancel the whole shebang if they won a majority, which isn't likely. But if they did, then that would presumably be on the basis of a strong remain turnout, in which case just cancelling it isn't an outrageous idea. Realistically, in any coalition scenario they'd push for another referendum.
This'll be the last UK election I can vote in, been out of the country for almost too long. Last vote like all my others is going to the LDs. They used to rule my county with an iron fist until the MP got caught banging an SAS bloke's wife lol
