Conservative leaflets obtained by the BBC suggest the party accepts the UK might not have left the EU by the time it has to fight an election. One says voting for The Brexit Party would mean "more delay" because Nigel Farage's party "can't deliver Brexit". The "new campaigning products", made available to agents and activists last week, also reveal some of the arguments the party may use in an election. Boris Johnson has insisted the UK will leave the EU at the end of October.
