The publishers behind the Sun and MailOnline are looking into allegations that Dan Wootton inappropriately offered colleagues tens of thousands of pounds in return for sexual material.

Wootton’s ex-boyfriend claimed last week that Wootton, who is now a presenter on GB News, used the pseudonym “Martin Branning” and offered individuals large sums of money in return for filming themselves carrying out sex acts.
