The Metropolitan Police made 11 arrests for alleged hate crime-related offences at the two major protests held in London on Saturday.
A total of nine have been linked to Tommy Robinson's Unite the Kingdom march and two to the Nakba Day pro-Palestine protest.
An estimated 60,000 people joined the former, while between 15,000 and 20,000 attended the Nakba Day rally, according to the Met.
A total of 43 arrests were made on the day, with 20 linked to the Unite the Kingdom protest and 12 connected to the Nakba rally, the force confirmed.
The remaining 11 arrests were not linked to either group, or their affiliation has yet to be confirmed, the Met added.
Approximately 4,000 police officers were deployed on Saturday, with four assaulted during the day and six subjected to alleged hate crime offences, the force announced in a post on X on Saturday evening.
The offences included those motivated by race, religion, sexuality and disability. A further seven hate crime offences remain under investigation, with suspects yet to be identified — all linked to the Nakba Day protest.
Three arrests were made as a result of live facial recognition technology, the Met added. All three individuals were wanted for failing to appear in court and none were affiliated with either of the protests taking place on the same day.
Mr Robinson, whose real name is Stephen Yaxley-Lennon, shared a video on X from the demonstration in which he declared: "Keir Starmer, the country's awake, your days are numbered."
In a separate clip, he claimed millions had attended the march. Taking to the stage, Mr Robinson urged those gathered to get involved in local politics.
Among the other speakers were former Apprentice candidate Katie Hopkins, television personality Ant Middleton, former actor Laurence Fox and former Conservative MP Andrew Bridgen.
Siobhan Whyte, mother of Rhiannon Whyte, who was murdered by a Sudanese asylum seeker, addressed the Unite the Kingdom protest, telling the crowd that Prime Minister Sir Keir Starmer "failed my daughter".
Polish politician Dominik Tarczynski, who claimed to have been banned by Sir Keir from entering the UK ahead of the rally, appeared on stage via videolink.
Organisers of the pro-Palestine rally estimated at least a quarter of a million people were in attendance. Labour MP Apsana Begum told protesters at the rally that the movement would not be divided by the "far right".
MP Diane Abbott declared they faced a "common enemy" in the "far right". She added: "They are viciously right-wing, viciously racist, they are anti-black, anti-Muslim, and viciously anti-semitic. We have to come together... to fight the racists, to fight the fascists, to fight the antisemites."
Your Party co-founder Zarah Sultana informed the demonstrators that Andy Burnham was "not an alternative" to Sir Keir and "is another establishment politician cut from the same Zionist cloth".
Former Labour leader and Your Party co-founder Jeremy Corbyn addressed supporters at the pro-Palestine demonstration in Pall Mall, saying that Westminster requires a shift in "policy" not "personalities".
