Police officers and litter-pickers will be on standby in Primrose Hill on Thursday to guard against the park being trashed by thousands of drunken partygoers – as it was on New Year’s Eve last year.

One year ago, residents were horrified to wake up on New Year’s Day and see their usually quiet village wrecked following the annual pilgrimage to the park to watch the ticketed central London firework display for free.

Broken glass and even human faeces were among the debris left behind after last year’s festivities, leading one resident to note that the neighbourhood was left looking “like a slum”.

This year, Royal Parks – which runs Primrose Hill – has pledged to supply extra litter-pickers and to work closely with Camden Police to minimise anti-social behaviour.

A spokeswoman said: “Last year visitors to the hill dropped a substantial amount of litter.

“This year, the Royal Parks will have extra litter pickers in place.

“However, we ask that people respect the park and are considerate to fellow users and the local community by leaving quietly and taking litter home or placing it in the bins provided.”

She added that revellers will have to leave the park by 1am. Setting off fireworks in Primrose Hill itself is banned.

A spokesman for the police said: “We are working closely with the Royal Parks police and local officers to ensure an appropriate policing plan is in place in an effort to keep the public safe and reduce anti-social behaviour and other crime related offences.”

Any visitors willing to brave the crowds will be rewarded with spectacular views of the main firework display, as well as smaller displays from across the capital.

Hampstead Heath is also a popular vantage spot to see the sky lit up on the night, and may be a less crowded option for young families due to its size.

Revellers won’t need to wrap up warm or bring their umbrellas, as it looks set to be a clear, balmy night, with temperatures predicted to be hovering around five degrees Celsius at midnight.

Transport for London (TfL) is once again providing free travel between 11.45pm to 4.30am on the bus, Tube, TfL rail, DLR and London Overground networks.
