This is the horrifying moment an elderly fan of the President was assaulted and knocked to the ground during a horrifying scuffle at yesterday's anti-Trump rally in London.

A mob in Parliament Square rounded on the the man and violently pushed him to the ground while yelling 'Donald Trump not welcome here'.

It happened at the poorly-attended demonstration where Jeremy Corbyn gave a firebrand speech railing against President Trump and lecturing the crowd about creating a 'better world'.

The video emerged after another Trump supporter was attacked with a milkshake by a mob chanting 'Nazi scum' at the same protest - that was attended by only around 10,000 people.

In the new video, the pensioner wearing a 'Make America Great Again' hat can be heard shouting 'get off' whilst the other men grab his jacket and pull him.

They then push him down onto the floor, leaving others around them outraged at the brutal forced used against the elderly man.

Others attending the rally then raise their hands and shout 'woah woah woah' to the violent protesters in order to stop them continuing their assault.

He is then helped up by members of the crowd and one can be heard saying 'have some respect, he is a senior citizen'.

Another said: 'When you act like that, you act like Donald Trump, so don't'.

The man is then lifted off the floor with many asking him if he is alright. The chanting then dies down as many look on horrified.

The men who had pushed him to the ground then disperse into the wider crowd.

It is thought that the man had stolen one of the anti-Trump placards and was holding it tightly to his chest, as he appeared to be walking away from the aggressive crowd.

It comes after another elderly man had milkshake thrown at him yesterday during the demonstrations, while a group of protesters yelled 'nazi scum' at him.

Video footage from the scene shows a number of marchers yelling at the semi-retired grandfather before he is hit with the beverage.

The man tells the angry mob that he is 'here to stay' before throwing the empty cup back at protesters as a sole police officer attempts to stop the incident from turning into a brawl.

The man claimed he was kicked in the legs, and attacked with a banner with a stick on the end. The demonstrators also attempted to remove his Make America Great Again hat - which he eventually got back.

Speaking to MailOnline, the man, who refused to be identified, said he was peacefully debating with 'moderate lefties' and 'having a laugh with the majority of them' before the demonstration turned violent.

He said: 'We have to put forward how aggressive the left can be - it's not us, you know if they want to call me right wing because I'm supporting Trump then I must be right wing, but I'm not a racist.'

Speaking of the moment he was attacked, the man added: 'I came out to support Trump, to stop the left who since we voted for Brexit have been protesting against democracy.

Last night Siobhan Prigent, who was one of the protesters who screamed 'Nazi scum' in his face, took to Twitter to apologise for her behavior.

In the video she can be seen holding a placard which says 'This episode of Black Mirror isn't funny any more! #NoThanksNazis'.

She wrote in a now-deleted tweet: 'I am very sorry for my behaviour today. I should have protested peacefully & I didn't, & I regret that.

'I've let myself down & I do understand that fully. There are two sides to every story, but my actions were my own, & that's on me. Please leave my family & friends out of it.'
