Reform UK’s chairman has predicted the party could win up to 400 seats at the next general election.

Zia Yusuf’s comments come as Reform has topped a series of national opinion polls.

He told BBC Radio 4’s Political Thinking podcast that he thought his party “will win between 350 to 400 MPs” at the next election, which must be held before August 2029.

Mr Yusuf said the party is “not a pressure group” and is “here to win”.

He added: “We need 350 to 400 incredible Reform MPs to transform the country.”

It comes after Nigel Farage’s party hit its highest-ever level of support in a poll yesterday.

The survey by Find Out Now put Reform on 29%, up two points from the week before.

Labour was second with 25%, while Kemi Badenoch’s Tories were 11 points behind the rebranded Brexit Party on 18%.

Reform also topped a YouGov voter intention poll for the first time earlier this week.

Mr Yusuf said he does “understand” potential concerns over the prospect of the party accepting a donation from tech billionaire Elon Musk.

He told the podcast: “I can understand those concerns… We’re going to play by the rules.”

Reform leader Mr Farage met Mr Musk, a close ally of Donald Trump, with the billionaire rumoured to be considering a large donation to the party.

Rules preventing foreign donations mean Mr Musk could only funnel any donation through one of his UK-based businesses.

Mr Yusuf also suggested he would be open to former Tory home secretary Suella Braverman joining Reform.

He said he has a “huge amount of respect” for the MP for Fareham and Waterlooville, and when asked if she would be a good Reform member, he responded: “If Suella wanted to join Reform UK? Yeah, absolutely.”
