A majority of police officers feel unsafe working at Notting Hill Carnival, a survey by the Metropolitan Police Federation has suggested.
As part of the survey, officers who have worked at the event over the last 10 years described it as "hell" and a "warzone".
There were more than 350 violent or sexual offences reported at the carnival in August, including the fatal stabbing of young mother Cher Maximen, according to the Met Police, and 61 attacks on officers.
However, the carnival's organiser said the survey had an "an anti-carnival agenda" and only represented the views of a minority of the 7,000 officers who work at the event.
