Notting Hill Carnival could be cancelled without 'urgent funding' from the government, its organisers have reportedly warned in a leaked letter.

It comes after a review of the festival, which takes place on August Bank Holiday weekend, identified 'critical public safety concerns'.

Last year, more than 300 people were arrested and eight people were stabbed during the event, which attracts up to two million visitors.

Ian Comfort, the Carnival's chair, has now said in a letter seen by the BBC that additional funding is needed to address the issues and make sure it safe to run.

He is understood to have written to Culture Secretary Lisa Nandy to request the money, which is 'essential to safeguarding the future and public safety of this iconic event'.
