The UK Independence Party (Ukip) is not worthy of the description "fruitcakes and loonies", the leader of the Monster Raving Loony Party's eastern region has said.
In a letter to The Independent, Lord Toby Jug said the use of the term "loonies" had become "cavalier" and it was his party who sought "the Holy grail of Looynism".
He wrote: "As the official party of protest, we Official Monster Raving Loonies strongly object to use of the terms 'fruit cakes and loonies' when describing Ukip.
Which one is the loony? Nigel Farage with Lord Toby Jug
"We who seek the Holy grail of Loonyism strongly object to the cavalier use of these terms."
He added: "Most Ukip members and supporters are nothing but opportunists, seeking a populist platform for their extremist views."
David Cameron famously branded Ukip members "fruitcakes, loonies and closet racists, mostly" in 2006.
At the 2010 general election the Loony Party's humorous policies included banning greyhound racing, to "stop the country going to the dogs", and their solution to the conflict between Israel and Palestine was to replace "the old road map... with a new sat nav instead".
Asked about his views on Nigel Farage's party this morning, the Prime Minister said: "I am not calling anybody anything".
