What began as a Conservative headache has become a Labour headache

Nigel Farage's prominence has only grown since he was elected as the MP for Clacton last July .

Support for Reform has surged to around 25 per cent and may overturn Labour ’s 14,696 majority in the Runcorn and Helsby by-election on 1 May .

Mr Farage is repositioning himself as a leftish populist.
