The UK Parliamentary standards watchdog has opened an inquiry into Reform Party leader Nigel Farage over an alleged gift of about £5 million that is reported to have been undeclared, the BBC understands. Both outlets say the decision comes from the Parliamentary Standards Commissioner, who has begun an investigation into the circumstances around the money. The Daily Mail identifies the commissioner as Daniel Greenberg and states the probe focuses on whether the payment was properly declared under Commons rules. The articles also report Farage’s public response, with the Daily Mail saying he vows to “put questions to bed once and for all.”

As of now, the sources provide no further details on the donor, the nature of the gift beyond its reported value, or the timing and compliance aspects under consideration. The inquiry is described as an initial standards process, meaning any findings would depend on the commissioner’s assessment of the evidence and relevant parliamentary rules.
