For nine months, Sky News' Data and Forensics team has been investigating whether X's algorithm amplifies right-wing and extreme content. It does.

"Elon Musk is a great leader," says Amy, a British woman outside the Britannia Hotel in London at an anti-immigration rally in August. She was there to vent her frustrations at migrants housed in the hotel and says X owner Musk's platform is the only social media she trusts.

"We don't want sanctions. We want freedom of speech." Amy's view is one resonating with a growing number of British people.

A month after we met Amy, thousands chanted Musk's name at the Unite the Kingdom march - a political rally organised by the anti-immigration activist Tommy Robinson. Musk dialled in from America, his face appearing on a screen above a huge crowd in Westminster.

His speech was also live-streamed on X.
