Nigel Farage, the far-right political leader riding a surge of support in Britain, has announced he will stand down as an MP and recontest his parliamentary seat. It is major gamble that could end his political career and comes amid intensifying scrutiny of the 62-year-old Donald Trump-ally's finances and donations. Speaking in London on Tuesday, local time, he said he would be triggering a by-election in his Clacton-on-Sea constituency.It's an unusual move which could serve as a circuit breaker for Mr Farage, who, facing the biggest crisis of his decades-long career, is attempting to shore up his position in Westminster and silence his critics.He has been accused of failing to declare donations and other benefits in the months before he was elected to the Commons in 2024."I've decided that the people of Clacton should be the judges of my actions," Mr Farage said, claiming the by-election would be "a chance to stick two fingers up to the entire establishment, to frankly tell them to go".While Mr Farage denies any wrongdoing, he is being investigated by the Parliamentary Standards Commissioner and has confirmed he received a £5 million ($9.63 million) "gift" from a Bangkok-based crypto billionaire.Mr Farage founded and leads the right-wing, populist Reform UK party, which is surging in national opinion polls, although it has only eight MPs in the country's parliament.Mr Farage has struggled to explain away the reports he has not been transparent about his financial arrangements.In late April, The Guardian revealed Mr Farage had failed to declare the £5 million payment from British-Thai political donor Christopher Harborne.Last week, The Sunday Times reported the Reform UK leader had not declared benefits he received from the British financier and convicted fraudster George Cottrell.These included several social media and security staff in the lead up to his 2024 election win, as well as the use of a property in central London.Mr Farage again denied any wrongdoing. In the UK, new MPs have to declare financial interests and "registrable benefits" received in the 12 months before they are elected, although personal gifts do not need to be disclosed.Mr Farage has had several roles in UK politics and was for more than two decades a member of the European parliament.He rose to particular prominence as the main campaigner for Britain to leave the European union, something it did in 2020.Mr Farage stood unsuccessfully for seat in the UK's lower house of parliament seven times before he was eventually elected in 2024."Let me be absolutely clear I have done nothing wrong. I have not broken the law in any way at all," Mr Farage said during a video address posted online in which he admitted to being "angry".He railed about the mainstream media and UK's major political parties during the at-times fiery update."And I would say this to you, the voters of Clacton. If I win, you win. Because if I lose, they win," Mr Farage said.
