Reform UK leader Nigel Farage is facing investigation by Parliament's standards watchdog over a £5 million gift he received from a billionaire donor.

Farage has described the substantial sum as a reward for his role in Brexit campaigning. The politician stated he "cannot be bought by anybody" in response to questions about the gift.

Separately, Reform UK has disclosed that Farage used earnings from his appearance on the reality television show "I'm a Celebrity" to purchase a £1.4 million house. The party made this revelation while the parliamentary investigation into the £5 million gift continues.

The Commons standards probe represents a formal parliamentary investigation into potential breaches of conduct rules regarding the declaration or handling of financial interests. Such investigations examine whether Members of Parliament have properly disclosed gifts, payments, or other financial arrangements in accordance with parliamentary standards.

The investigation comes as Farage continues to lead Reform UK, having returned to frontline politics after previously stepping back from active leadership roles in Brexit-related campaigns.
