Labour last night sacked a local election candidate who had called the Queen "a parasite" and "vermin".
Peter White had at first defended his rant before later apologising "unreservedly". But it was not enough to save him from being sacked by the regional board of the London Labour party, who had demanded an explanation.
White had been due to fight for a seat on Havering council in the capital next year.
He was axed for comments which were posted on the Facebook page of Conservative MP Andrew Rosindell, who has been campaigning for the Queen's diamond jubilee in 2012 to be marked by a public holiday.
White said: "What is the point of celebrating the diamond jubilee of someone who is born into a position of privilege, she is a parasite and milks this country for everything she can."
He went on: "She has more front than Margate asking for extra money from the civil list. Maybe she should sell a couple of her properties. Maybe if she wants Buckingham Palace to be maintained from public funds she should open it to the public.
"Don't get me wrong, I have no problem with a public holiday but let's have one that means something, rather than celebrating vermin."
Rosindell, MP for Romford, said White's online attack on the monarchy had prompted messages of outrage from people around the world, including many republicans.
"Frankly his actions have warranted the decision. I think it is fully understandable that Labour would want to disassociate themselves from him. These remarks were shameful and caused great offence to people across the world. There has been an enormous response. Even republicans are disgusted at the kind of words he used. It is beyond the pale to say things like that whatever your views."
White apologised last month in a statement issued by the party, which said: "The way I expressed myself was totally inappropriate. I regret what I said and apologise unreservedly."
Labour is now looking for another candidate for the South Hornchurch ward in Havering.
