Andrew Sparrow's Guardian politics live blog leads on Michel Barnier saying it is "perfectly possible" to negotiate UK rejoining the EU without an obligation to join the euro, but that free movement and single market membership are non-negotiable – rebutting Nigel Farage's claim that rejoining means signing up to the euro. The blog also flags Sadiq Khan facing the London assembly, a Farage press conference with Danny Kruger, and the Bank of England's expected interest rate rise.
