Three artworks by street artist Banksy have cost taxpayers almost £150,000 in cleaning operations and security so far, with the bill expected to rise. The largest single cost relates to a mural painted on the Royal Courts of Justice in September 2025, where removal efforts and security have so far cost more than £85,000. The Ministry of Justice (MoJ) says it has spent £50,000 trying to remove paint from the wall of the Grade II-listed building in Carey Street. The latest costs relate to a mural depicting a judge in a wig battering a protester with his gavel, which appeared on the Royal Courts of Justice in London on 8 September 2025. Banksy claimed the image as his own work, by posting it on his website and Instagram account.
