Nigel Farage, the Brexit campaigner who leads the UK's right-wing Reform UK party, resigned as MP for Clacton on 7 Jul, forcing a by-election he intends to contest. The resignation follows weeks of scrutiny over an undeclared £5mn gift from Christopher Harborne, a billionaire investor with a roughly 12% stake in Tether, the issuer of the USDT stablecoin.
