Glastonbury Festival organisers have issued a rare warning that they may be forced to close part of the festival site ahead of a highly anticipated and politically charged performance by Irish hip hop group Kneecap.
The Belfast trio - Mo Chara (real name Liam Óg Ó hAnnaidh), Naoise Ó Cairealláin, and JJ Ó Dochartaigh - are due to perform on the West Holts Stage at 4pm today.
