A string of bands have pulled out of the Victorious music festival hours before they were due to perform after Irish folk music band The Mary Wallopers claimed they were 'cut off' for displaying a Palestinian flag.

The Last Dinner Party, Cliffords and The Academic announced on Saturday that they would no longer be performing at the Portsmouth music festival following Friday's incident.

The organisers, who claimed the band had their set cut short for using a 'discriminatory' chant, have since issued an apology to the band and pledged to make 'a substantial donation to humanitarian relief efforts for the Palestinian people'.

Rock band The Last Dinner Party said they would boycott the festival in a statement shared on their Instagram page.

The statement said: 'We are outraged by the decision made to silence The Mary Wallopers yesterday at Victorious. As a band we cannot cosign political censorship and will therefore be boycotting the festival today.
