The UK's Chief Rabbi has strongly criticised "the airing of vile Jew-hate at Glastonbury" after a live broadcast of Bob Vylan's performance at the festival went out on the BBC, during which the band's singer led the crowd in chants of "death, death to the IDF [Israel Defense Forces]".

Writing on X, Sir Ephraim Mirvis wrote: "This is a time of national shame. The airing of vile Jew-hatred at Glastonbury and the BBC's belated and mishandled response, brings confidence in our national broadcaster's ability to treat antisemitism seriously to a new low.

"It should trouble all decent people that now, one need only couch their outright incitement to violence and hatred as edgy political commentary, for ordinary people to not only fail to see it for what it is, but also to cheer it, chant it and celebrate it. Toxic Jew-hatred is a threat to our entire society."

In a statement issued on Monday, the BBC said: "The team were dealing with a live situation but with hindsight we should have pulled the stream during the performance. We regret this did not happen."

A criminal investigation has now been launched over performances by both Bob Vylan and Irish-language rap trio 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.

A statement added: "This has been recorded as a public order incident at this time while our enquiries are at an early stage."

Speaking in Parliament on Monday after the announcement, Culture Secretary Lisa Nandy called the scenes broadcast "appalling and unacceptable".
