It seems inevitable that the European elections this month will be seen as a litmus test of the British public's attitude to Brexit, especially when it comes to a second referendum. And, if Nigel Farage's Brexit party triumphs over the Remain coalition, the case for a People's Vote will be weaker than ever.

They may be even unhappier though when they realise that Change UK candidates aren't even sure why they're not Lib Dems. The Change UK MEP candidate for south-west England, Rachel Johnson, was interviewed by Radio 4 this morning, and suggested that her new party was a 'fresh alternative to the Lib Dems.'
