Labour candidate Jane Aitchison ranted online about 's***' jobs at McDonalds, Waitrose shoppers being 'scum' and 'scroungers in the Royal Family

A Labour candidate fighting for a marginal seat ranted online about 's***' jobs at McDonalds, Waitrose shoppers being 'scum' and 'scroungers in the Royal Family.

Jane Aitchison's Twitter tirades were exposed just days after she was selected to fight Pudsey in West Yorkshire.

The Momentum-backed candidate apologised tonight for her 'unbecoming' language and vowed to fight to turn the seat red at the next election.

Conservative Stuart Andrew won the seat by just 331 votes at last year's election and the constituency is a top Labour target.

Responding to the news McDonald's was creating 2,500 new jobs, she tweeted: 'S*** food. S*** jobs. This is what they want for us.'

Commenting on a news report about a 'middle class revolt' at Waitrose over a free coffee offer she blasted: 'From the comments seems real scum already shop there.'

And in August 2012 the candidate - a long term trade union activist - attacked Prince Harry after tabloid pictures of him emerged in Las Vegas.

She said: 'Time to strip Harry of his royal title. Why stop at him? Royal b*******.'

An anonymous Labour MP told the Yorkshire Post tonight the rants would damage the party's chances of winning the seat.

They said: 'We might as well kiss that seat goodbye for Labour. I know the electorate in Pudsey will take a different view to the selectorate in Pudsey Labour Party.

'I don't think the party members in Pudsey are representative of the community.'

The MP went on: 'She's ultra-left, once people know what that means they won't vote for it.

'People from Leeds aren't radical revolutionary socialists, some of them are Labour, some of them are Conservatives but they're not revolutionaries and they don't believe in revolutionary politics.'

Ms Aitchison told MailOnline: 'I recognise that the language used in some tweets I made years ago is unbecoming of a parliamentary candidate and I apologise.

I'm thrilled to be selected as Labour's candidate in this important seat and I am putting forward Labour's positive message of hope and optimism here, with the aim of becoming the MP for the many not the few.'
