Five protesters have been arrested at the pro-Brexit March to Leave demonstration in London.
Police said two people were held on suspicion of assault, one for being drunk and disorderly and another for assaulting a police officer.
A fifth person was arrested after they were identified as being wanted for an offence in Hertfordshire.
Thousands of people opposed to the UK delaying its withdrawal from the EU marched through central London, as MPs rejected Theresa May’s Brexit deal for a third time.
Some protesters cheered as the prime minister suffered another Commons defeat, but others feared it meant a second referendum was on the cards and were frustrated by the possibility of a lengthy delay to Brexit.
The final leg of March to Leave, which began in Sunderland two weeks ago, saw protesters file from Fulham towards Parliament Square.
The march was joined by prominent Brexiteer Nigel Farage and featured speeches from English Defence League founder Tommy Robinson and UKIP leader Gerard Batten.
Demonstrators were filmed jostling with police and journalists after the planned speeches and protests ended, and one group were seen appearing to push camera crews away.
Two MPs said they were abused during the demonstrations.
The SNP’s Joanna Cherry wrote on Twitter that she had been called a “traitor” and told to “go back to her own country” as she walked home.
Labour MP Lisa Nandy also said she was “accosted” outside Parliament and staff had been told to leave the building for their own safety.
There were mixed reactions after the Commons vote, although Mr Farage celebrated the defeat of Mrs May’s “appalling” agreement and said he would rather have an extension to Article 50 or leave with no deal immediately.
A no-deal Brexit would see Britain leave the EU with no agreements in place for what a future relationship will look like.
One protester, 52-year-old saleswoman Louise Hemple, said: “Excellent. We’re now on track for a no-deal.
“And that will mean we’ll have complete control, which is what we Brexiteers voted for.”
Roger Hopkins and Charlotte Clifford, from Eastbourne, said they were pleased the agreement had been defeated as it was a “bad deal”.
Mr Hopkins said: “What I really really hope for now is to come out on WTO (World Trade Organisation) terms – it’s not crashing out or anything like that.”
