The event occurred after a large march against the far-right in London, attended by Polanski and newly elected MP Hannah Spencer. The march, organized by the 'Together Alliance', brought together over 100 charities, campaign groups, and trade unions. According to organizers, around half a million people joined the protest, which went from Park Lane to Trafalgar Square via Whitehall.
Polanski shared a photo of the event on X (formerly Twitter) along with a message about the importance of unity and hope. The tweet drew a reaction from Laurence Fox, who questioned the meaning of 'far-right' and the normality of hope.
