Several thousand anti-lockdown demonstrators have marched through central London despite restrictions on mass gatherings during the COVID-19 pandemic.
The event on Saturday was billed by organisers: "Unite for Freedom".
The protesters view COVID-19 restrictions as unnecessary and a breach of their human rights. They oppose vaccinations, mask-wearing and so called health passports.
Media reports put numbers at about 10,000, though the Metropolitan Police did not confirm a figure.
Protesters chanted "Freedom" and "Take off your mask" and some carried placards saying: "No to vaccine passports" and "Lockdowns kill".
Most were unmasked.
A spokesman for the Metropolitan Police said he was not aware of any arrests.
England has relaxed its lockdown restrictions in recent weeks.
Non-essential shops and outdoor hospitality reopened on April 12, but indoor gatherings are still banned until May 17 at the earliest.
The latest protests come as more than half of the UK's total population has received a first dose of a coronavirus vaccine, figures show.
NHS England data up to April 23 shows that of the 38,189,536 total doses given in England so far, 28,102,852 were first doses - a rise of 107,656 on the previous day.
It means the UK first dose total so far is now 33,496,293, with more recent figures still to be reported by Wales, Scotland and Northern Ireland.
