From September 14 it will be illegal to hold a social gathering in England of more than six people. Weddings, funerals and sports matches which have social distancing measures in place will be exempt.
Anyone who breaks the new rules risks a fine of £100, doubling for each offence up to £3,200.
Currently the police only have powers to disperse gatherings of more than 30.
Taking to Twitter the Brexit Party leader sharply criticised the new rules.
He commented: “This draconian law that comes in from Monday to allow gatherings of only 6 people will not be respected by protestors and those going to raves, so why should the rest of us comply?”
In June London, and other cities across the UK, saw large ‘Black Lives Matter’ protests following the death of George Floyd in Minnesota during an altercation with police.
Piers Corbyn, brother of the former Labour leader, was fined £10,000 at the end of last month for organising an anti-lockdown protest in Trafalgar Square.
The 73-year-old said he was being targeted as an “organiser” after being arrested on the afternoon of August 29.
Boris Johnson explained the rational for the new restrictions on social gatherings during an address on Wednesday.

The Prime Minister said the rules had become “quite complicated and confusing” and needed “simplifying and strengthening”.
He added: “I want to be absolutely clear, these measures are not another national lockdown.
“The whole point of them is to avoid a second national lockdown.
“It breaks my heart to have to insist on these restrictions.”
The UK has seen a sharp increase in the number of confirmed COVID-19 cases raising fears of a second wave.
On Wednesday an additional 2,659 cases were confirmed across the country.
Cases have risen nationwide from 12.5 infections per 100,000 people to 19.7.
These cases exist disproportionately amongst young people with 54 cases per 100,000 people for those aged 19 to 21.
Thus far the virus has been far more deadly to the elderly and those with certain pre-existing medical conditions.
There are concerns some young people have been ignoring social distancing advice when attending parties and other social gatherings.
The return of schools and universities this month risks further increasing the rate of infection.
The Government hopes to increase testing capacity to 500,000 per day by the end of October.
