Liam Óg Ó hAnnaidh, known by his stage name Mo Chara and a member of the Irish rap group Kneecap, appeared at Westminster Magistrates Court in London on August 20, 2025, facing terrorism charges. The charges stem from allegations that he displayed a Hezbollah flag, a proscribed terror organization, during a Kneecap concert in London in November 2024. Mo Chara denies the charges, and his defense has argued that the case was mishandled. The court has granted him bail, and a ruling on whether he will stand trial has been postponed until September 26, 2025. Hundreds of supporters gathered outside the court in solidarity with Mo Chara, chanting slogans in support of Palestine. Despite controversy and calls for boycotts, Kneecap performed at the Rock en Seine music festival in Paris in late August 2025, where they reaffirmed their pro-Palestine stance and criticized Israeli government policies. The festival organizers resisted pressure to drop the group. The case raises broader questions about artistic expression, free speech, and political activism within the context of counterterrorism laws in the UK.
