An Asian UKIP candidate is accused of calling a Tesco trolley collector a 'f***ing foreigner' and told him to 'go back to where you came from' in a car park row.

Sam Naz, 33, who finished fifth in her bid to beat Tory Zac Goldsmith to become MP for Richmond Park and North Kensington in London, allegedly racially abused Mohammed Wafta, 48, after he intervened in an altercation between her and another customer.

Mr Wafta, who is of Muslim background, told Snaresbrook Crown Court that he spotted her arguing with the man at the supermarket in Leystone and went over to see if she needed help.

When he intervened, the man got into his car and drove off - only for Naz, who is the daughter of Pakistani immigrants, to turn her anger on the Tesco worker.

Mr Wafta told Snaresbrook Crown Court that he spotted Naz arguing with the man, at the supermarket in Leystone, and went over to see if she needed help

Mr Wafta told the hearing: 'I went outside in the car park to collect trolleys between 4pm and 5pm.

'I heard an argument between a male and women by the last exit.

'The only person I heard was the lady calling for security and the police to come and arrest this man.

'I left the trolleys and went between the two people. The man was definitely about to punch her in the face.

'He was saying no woman can say the 'f***' word to me and I let her go. She was holding the man who was about to run away.

'I was trying to calm her down saying I will call the police. The man got in his car with a baby in the front.

'The woman held onto the handle, he got off and they were arguing. He then got back in the car and drove off.'

Mr Wafta told the court Naz then turned her ire towards him, mistaking him for security.

'She started shouting and swearing. She said: 'What kind of f***ing security are you?'

'What kind of f***ing man are you? You aren't even f***ing born here, you don't belong here.'

Mr Wafta told the court he had tried to calm her down, saying he was not security and was only trying to help her.

He said: I told her you are too pretty to say those words, she had used them over 50 times.

'I said stop using those words, if you look at me, and look at you, we are both foreigners.'

'She then told me: 'No, I was born here.'

He told the court Naz had then stormed into the Tesco promising to 'make sure they f***ing sack you'.

Mr Wafta said he had followed Naz into the store, where the swearing continued.

He said: 'I came in and she pointed at me and began shouting and swearing at me.

'My manager Chris grabbed me from my back to get me away from the quarrel or fight.

'When Chris had grabbed me and dragged me away I was about to try and approach her.

'I lost my temper, maybe I'd have done something bad.

'I felt very upset, in all my life I've not been cussed at like that.'

Prosecutor Swarma Kodikara said: 'You will probably hear from Ms Naz as to how this came about.

'She repeated this abuse a number of times to this man who had tried to rescue her from a rather dangerous situation.

'That did not seem to occur to Ms Naz as she kept calling him a "f***ing foreigner" and a "f***ing b***ard" a number of times.'

Naz later took up her fight with 31-year old store manager Christopher Sanders and demanded 'this man ought to be sacked'.

She told Mr Sanders that he was a racist before she left the store.

Naz was arrested on March 29 last year and told police that Mr Wafta had stood by and said: 'You deserve it' while she was being assaulted by the unknown male.

The jury also heard about Naz's run as a UKIP candidate - 'a party which some of you may think has controversial views about immigration'.

'Ms Naz explained in her interview that she believed she was a target by some of the witnesses there who knew her as a member of the UK Independence Party,' said Ms Kodikara.

She added that they may have been 'hostile to her choice of political party'.

'What we have to prove this case is the evidence of Mr Wafta and the evidence of independent eyewitnesses who will come to this court and say Ms Naz had made such racial remarks to Mr Wafta,' added Ms Kodikara.
