A woman filmed unleashing a vile torrent of racist abuse on a crowded tram through Croydon has been struck off from her role as a dental nurse.

Emma West, 37, from New Addington, made headlines around the world when footage of her foul-mouthed rant - in which she maligned "a load of black people and a load of f***ing Polish" - was uploaded onto YouTube in November 2011.

She admitted guilt nearly two years later at Croydon Magistrates' Court, by which time more than 2.2 million people had watched the video.

Magistrates ordered West, who also admitted slashing her partner with a knife and assaulting a police officer, to carry out community service.

She was struck off after the General Dental Council ruled she posed a risk to patients and that her "appalling" behaviour had brought the profession into disrepute.

At a hearing on Friday, the council's professional conduct committee watched the YouTube clip, entitled My Tram Experience.

The footage, which lasts two minutes and 25 seconds, sees West holding her then four-year-old son on a tram from Wimbledon to New Addington. 

She shouts at passengers: "What has this country come to? A load of black people and a load of f***ing Polish.

"You ain’t English. No, you ain’t English either. You ain’t English. None of you’s f***ing English.

"It’s nothing now. Britain is nothing now. My Britain is f*** all now."

West was arrested and charged with a racially aggravated public order offence within days of the footage becoming viral.

But she was not convicted until June 2013 after her lawyers argued she was not fit to stand trial.

It then emerged the mum-of-two had admitting stabbing her partner of 12 years, Ricky Metson, with an ornamental knife during an argument at their home.

A spokeswoman for the General Dental Council committee said: "Her conduct was truly appalling. It clearly has the capacity to bring the profession into disrepute and to undermine public confidence in its standards.

"Furthermore, her violent and abusive conduct would demonstrate a real risk to the safety of patients. 

"In relation to her racially aggravated offence, this was committed in a public setting and received further public exposure, as a person had uploaded the video clip to the internet which has been viewed extensively."

Miss West, who was already suspended from her job at a dental clinic in New Addington, will be struck off from the dental practice register after 28 days if she does not appeal.

She did not attend or send anyone to represent her at the hearing.
