An email exchange marked “private and confidential” between over 30 individuals was reportedly leaked to the band, with the outlet quoting a solicitor’s letter sent to those on the chain in response.
The letter claimed: “Your correspondence seeks to monopolise your status within the industry to impose direct and concerted pressure on Glastonbury, to restrict freedom of expression.
"Such a direct and coordinated approach seeks to create a chilling effect upon the wider music industry whereby those who hold opposing views, will seek to impose their own view on the wider industry.
"We write to put you on notice that we are now formally instructed to commence high court civil proceedings for damages for the damage you have inflicted on our client’s reputation.
“However, before our clients formally seek to issue pre action correspondence, we write to offer you the opportunity to resolve these matters by way of an immediate and unequivocal apology.”
Kneecap have previously claimed that they are the victims of a “smear campaign” orchestrated by “members of the establishment” to try and “silence” their anti-Israel advocacy.
They have also shared a tweet on the band’s official feed claiming that Israel “owns politicians” and “controls corporate media”.
Glastonbury has previously declined to respond to the JC’s requests for comment.
