Keir Starmer said he didn't think it was "appropriate" for Kneecap to play Britain's biggest festival while member Mo Chara faces terrorism charges.

Irish-language rap group Kneecap has peformed for tens of thousands of fans at the Glastonbury Festival despite controversy and criticism from British politicians.

The Northern Irish trio have been at the center of controversy since their Coachella performance back in April. At that show, they displayed a message that read: “Israel is committing genocide against the Palestinian people. It is being enabled by the U.S. government who arm and fund Israel despite their war crimes. F— Israel; free Palestine.”

Organizers of the Glastonbury Festival said Sunday they are "appalled" by the onstage statements of the punk duo Bob Vylan, whose singer led the crowd in a series of chants including "Death, death to the IDF" and "Free Palestine" the day before.

The senator from Texas has accused fans at the music festival of being "antisemitic zealots" after being led in chants about the Israel Defense Forces.
