The Met’s "robust" policing plan include the monitoring of coaches coming into London to ensure that demonstrators cannot pile in from areas outside the capital.
More than 150 demonstrators were arrested at an anti-lockdown protest based around Trafalgar Square on 5 November, to mark the fist day of the nation’s second national shutdown.
The protestors, including Jeremy Corbyn’s brother Piers Corbyn, claim the lockdown and other measures brought in under Covid-19 legislation are whittling away at civil liberties. He was arrested at the demonstration.
The protesters on Saturday are expected to meet around King’s Cross.
One of the organising groups StandUpX tweeted: "We are taking over in the thousands in London on Saturday 28th November 12pm Kings Cross Station."
Jake Wright tweeted: “Roll on the protests that will be happening across London this weekend and I have a feeling that many thousands will be coming to the anti-lockdown protests in London this Saturday."
But police warned the demonstrators would be met with officers enforcing Covid laws.
The Met said in a statement: "Ahead of a planned protest on Saturday, 28 November, the Met is urgently reminding those looking to attend that protest is not currently a permitted exemption to the prohibition on gatherings under the current Coronavirus regulations.
"Strict regulations have been introduced by the Government nationally to help prevent the spread of Coronavirus. This means that anyone gathering for protest risks enforcement action by officers.
"A robust policing plan is in place throughout the weekend and officers will take action if they witness breaches of the regulations.
Chief Superintendent Stuart Bell, policing commander for this weekend, said: “The Met has a proud history of facilitating protest. However, our city is in a critical fight against Covid-19 and we cannot allow gatherings to jeopardise the progress and sacrifices our communities have made in fighting this virus.
“That is why we will be taking action in relation to prohibited gatherings on the streets of London, including those related to protest across the capital this weekend. Our top priority is public safety and that is why we cannot allow individuals to break the law and put their health and the health of their friends, family and the wider community at risk. If you are planning on attending a gathering, I would urge you to reconsider and stay at home.”
Across the week, officers have been engaging with policing partners nationally, as well as coach companies, following information that protest organisers were looking to hire coaches and travel to London from other parts of the country. Part of this Saturday’s policing plan will involve monitoring coaches travelling into the capital.
Chief Superintendent Bell, continued: “This type of behaviour not only breaks the law, it also risks spreading the virus between multiple areas of the country. It is for this reason that we urge people not to travel into London and this is also why we will be taking appropriate enforcement action if this happens.”
