Avon and Somerset Police launched a criminal investigation into comments made on stage by the Irish language rap trio at the music festival. On Friday, the force said that detectives had sought advice from the Crown Prosecution Service and chosen not to take any further action against Kneecap on the grounds that there was "insufficient evidence to provide a realistic prospect of conviction for any offence".

Kneecap called the investigation "political policing intimidation" and said their performance was a "celebration of love and solidarity". "This is political," they said. "Every single person who saw our set knew no law was broken, not even close." Kneecap had faced weeks of controversy over their pro-Palestinian stance, with Sharon Osbourne calling for their US visas to be revoked over messages they displayed on stage at Coachella.

The question over whether Kneecap should even perform at Glastonbury drew comment over the weeks before the festival, with the prime minister stepping in to say he did not think it was "appropriate". Group member Liam Óg Ó hAnnaidh had appeared in court charged with a terror offence, related to alleg-edly displaying a flag at a gig in November in support of proscribed organisa-tion Hezbollah. He denies the charge.

Kneecap did perform but the BBC did not livestream their performance. Police said that their enquiries into pop-punk duo Bob Vylan continue. The duo, whose set was broadcast live, led the crowd at the festival in chants of "death, death to the IDF [Israel Defense Forces]". Culture Secretary Lisa Nandy called the scenes "appalling and unacceptable", and the BBC apologised for not cut-ting the feed. Police did not specify which part of Bob Vylan's or Kneecap's sets were subject to criminal investigation. But in an earlier statement they said that they had recorded them as a public order incident. (BBC/ EPA/Shutterstock)
