People gathered in London for what was billed as a free speech rally, spearheaded by Tommy Robinson and included an appearance from Elon Musk in a live interview broadcast on stage.

The Metropolitan Police said it estimated around 110,000 were in Whitehall for the Unite the Kingdom event, while organizers said helicopter footage showed millions of people attending the rally.
