A new Opinium poll indicates that Nigel Farage's personal approval rating has fallen to its lowest point since the 2024 general election, coinciding with continued scrutiny over his financial affairs.

According to the survey, Farage's net approval rating has dropped to -27, with more than half of respondents expressing an unfavourable view of the Reform UK leader and only around a quarter viewing him positively.

The findings also show Reform UK's voting intention falling to 24 per cent, a two-point decline from the previous week and the party's weakest result in an Opinium poll for more than 18 months.Labour polled at 19 per cent, the Conservatives at 18 per cent, the Greens at 16 per cent and the Liberal Democrats at 12 per cent.

The decline follows ongoing controversy surrounding a £5 million gift received by Farage from Thailand-based crypto investor Christopher Harborne, which is the subject of a parliamentary standards investigation.

Additional reports have also raised questions about financial support allegedly provided by George Cottrell, a convicted fraudster, including claims that he paid for party office expenses that were not declared as donations.

Reform UK strongly denies any wrongdoing and insists it has complied with all legal donation requirements, describing the allegations as politically motivated attacks by the establishment.

Farage has also triggered a by-election in his Clacton constituency, framing the contest as a battle between ordinary voters and the political establishment.

Polling experts suggest that while Farage's core supporters remain loyal, the controversy could discourage potential Conservative defectors whose support would be essential if Reform UK hopes to become the dominant force on the political right.
