I doubt Corbyn will get the votes to get in but he WILL split any remaining Labour vote, increasing reform, Robert Lowe's party if it gets off the ground fast enough and a few independents or more national parties share.

But I think in the next election the UK has, when it might happen (as there are rumours Starmer might call next year to head off corbyn before he's established), Labour, conservatives, lib dems and SNP will be devastated.
