Labour has seen a slump in support since Keir Starmer stepped up his personal abuse of Nigel Farage, a survey found yesterday.

The Prime Minister has launched a series of scathing attacks on the Reform leader in recent days, branding him the 'enemy' on Saturday, calling his migration policies 'racist' on Sunday and using his Labour conference speech to question his patriotism.

Sir Keir stepped up the offensive again yesterday, claiming Mr Farage is responsible for the Channel crisis – and even describing the dinghies packed with illegal migrants as 'Farage boats'.

But a new poll yesterday suggested the tactic may have backfired. The More in Common survey, conducted over the weekend, recorded a five-point fall in support for Labour.

The poll of more than 2,000 people found Reform's lead over Labour had jumped from three points to ten in a week, with Mr Farage's party up two points to 30 per cent and Labour down five to 20.
