The Irish rap trio has drawn widespread criticism in recent months, with U.K. politicians condemning the choice to allow them to perform at the musical festival.

Kneecap’s performance at Glastonbury Festival will not be live-streamed but is likely to be made available on-demand, the BBC has said.A number of politicians have called for the Irish rap trio to be removed from the line-up and Prime Minister Sir Keir Starmer said their performance would not be “appropriate” after one of the members was charged with a terror offence.

A criminal investigation has been launched over performances by Bob Vylan and Kneecap at Glastonbury on Saturday, Avon and Somerset Police has said. The force said it had appointed a senior detective to investigate whether comments made by either act amounted to a criminal offence after reviewing footage.
