The organisers of the Glastonbury Festival have apologised for the display of a poster suggesting that Jews control the media.

The framed image, measuring around four feet by two feet, was hung in the Shangri-La art section of the festival and featured the words "There are 500 Newspapers, 100 Magazines, 9000 Radio Stations + 2400 Publishers - All Controlled by Six Corporations - The Six Are Owned By Rothschild".

It included logos of the six companies in question - Warner Brothers, Viacom, General Electric, Newscorp, CBS and Disney. None of the companies in question are owned by N M Rothschild & Sons.

One festival-goer, who did not wish to be named, said he complained to five members of the festival staff but they ignored him. He then stationed himself next to the poster to explain to people who saw it that "it was factually incorrect and a popular conspiracy that Jews control the media".

Social media users, including the actress and JC columnist Tracy-Ann Oberman, tweeted the festival to ask whether organisers were aware that the poster was on display.

Glastonbury responded on Sunday evening, at the end of the festival, saying that they were addressing the issue.

In a statement on Wednesday, a spokesperson said: "As soon as we were made aware of the complaint by a member of the public, the organisers of Glastonbury Festival and the organisers of Shangri-La took decisive steps to remove the poster from display.

"We would like to apologise unreservedly for any offence caused."
