The major announcement in Jo Swinson’s closing speech to conference on Tuesday, much trailed, was that the Liberal Democrats – were they to form a majority – would revoke Article 50 on their first day in government, ending Brexit overnight. She decried both Labour and Conservative as ‘tired old parties’, and suggested that Boris Johnson – somewhat perplexingly – was acting like a ‘socialist dictator’, while linking Jeremy Corbyn and Nigel Farage in a feat of rhetorical contortion. As if to prove the Lib Dems’ moderation in all things, she unveiled a lukewarm climate policy, aiming for net-zero emissions by 2045, knocking five years off the government’s goal but giving themselves far more wiggle-room than the target of 2030 due to be debated by Labour next week.
