An NHS worker has apologised for screaming 'Nazi scum' at a Donald Trump supporter who was covered in milkshake at a protest earlier today.
Siobhan Prigent, who is based in London, took to Twitter to say she was 'very sorry' for her behaviour at the demonstration in Parliament Square.
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.
A woman, who is believed to be Ms Prigent, can be seen holding a placard which says 'This episode of Black Mirror isn't funny any more! #NoThanksNazis'.
In the clip, a 'Trump Stinks' face mask also appears to be dangling from the woman's poster.
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.

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
