The Royal Parks has warned that people planning to gather for an annual cannabis demonstration in Hyde Park could be arrested.
Thousands are gearing up for the annual ‘420 Day’ rally in Hyde Park on Sunday, which is part of an international movement to protest against cannabis being illegal.
However, Royal Parks, which takes care of Hyde Park, has said the event will be taking place without its permission, adding that the demonstration breaches its regulations.
The charity, which looks after London’s eight royal parks, added that “enforcement of the law and of park regulations is a matter for the Metropolitan Police”.
But what is the event all about, and is it safe to go if you were planning on attending?
What is the 420 rally and why is it taking place?
420 at Hyde Park is a cannabis rally that has been held every year on April 20 since 1968.
It is part of an international movement to protest against cannabis being illegal with Royal Parks saying they “anticipate that thousands of people will turn up to take part”.
The event is organised by the 420 Committee and is supported by a range of charities and organisations.
Patients Cann UK, the UK's patient-led advocacy organisation for medical cannabis community said: “We are inviting the medical cannabis community, along with friends and supporters, to a relaxed and inclusive picnic at Hyde Park. This gathering celebrates community, conversation, and the spirit of togetherness. Please note, while the gathering has a special nod to medical cannabis culture, it is not a PatientsCann UK or Medical Cannabis event. Attendees are kindly requested to follow all Royal Park guidelines and local regulations, ensuring a safe and enjoyable experience for everyone.”
What do the police say?
The police have said they are keeping a close eye on the build-up to the event, and will have officers around on the day.
Met Police spokesperson told the Standard that there will be a “strong and visible police presence across Hyde Park” when the rally takes place.
A Met spokesperson said: “The Met is aware of the 420 Day rally, also known as the cannabis day event, in Hyde Park on Sunday, 20 April and have a policing plan for the day. Using cannabis and other recreational drugs is illegal. Officers will intervene and use enforcement options where proportionate and necessary.
“Our main priority is to ensure park users are safe and achieving that requires officers to make pragmatic decisions, potentially prioritising those offences that pose the most immediate risk.
“Officers will enforce legislation under the Misuse of Drugs Act 1971 through community resolution orders, penalty notice for disorder, postal charge requisitions and arrest, particularly if there is associated anti-social behaviour, disorder or crime.
“There will be a strong and visible police presence across Hyde Park. We encourage park users to speak to officers if they have concerns. Always call 999 in an emergency.”
How many people are arrested each year at the event?
Six people were arrested at the annual get-together in 2024.
In 2023, four people were arrested at the event. Two were arrested for possession with intent to supply, one for assault on an emergency worker and a fourth for failing to comply with park regulations.
Drinks were said to have been thrown at police officers moving in to apprehend cannabis users breaking the law by openly smoking in public.
What is the UK’s legal stance on marijuana?
At present, cannabis is deemed a Class B drug.
Under the Misuse of Drugs Act 1971, it is illegal to possess, produce, supply, import or export cannabis in the UK.
However, under the Misuse of Drugs Regulations 2001, the law does allow for the legitimate use of “some controlled drugs for medical, dental or veterinary purposes”.
The law states that any amount of cannabis can result in an unlimited fine and up to five years in prison, while the cultivation or supply of cannabis can lead to an unlimited fine and up to 14 years in prison.
Which countries have legalised marijuana?
Some countries have lifted laws on cannabis use in recent years.
In 2024, Germany became the third European Union country to legalise the use of cannabis for personal use, following Malta and Luxembourg.
In 2022, Thailand also legalised the drug, as did Mexico in 2021.
Other countries that have legalised cannabis use include Canada, South Africa, Georgia and Uruguay.
