UKIP by their founder

Seemingly not noticed much in the current furor about David Cameron accusing the UK Independence Party of containing fruitcakes, loonies and closet racists mostly" has been the supporting comments of Alan Sked who founded UKIP before leaving it:

He told BBC Radio 4's Today programme he agreed with Mr Cameron's assessment of UKIP, adding: "There is a trend of this party to the far right. After I left it became much, much more in evidence and it is in evidence today."

Sked is not popular with today's UKIP politicians and it's easy to see why, given his observation as to why UKIP MEPs seem so keen to take their seats:

"Given that there is little reason to occupy seats and then vote No to everything, one could easily conclude that UKIP candidates are in effect standing for the money - salaries, pensions and expenses."

UKIP's Nigel Farage is currently saber rattling about suing both Cameron and Sked for libel. Has he also sued over past coverage like this from The Grauniad?

But Mr Farage has struggled to shake off his xenophobic image. He is currently embroiled in a row over Martyn Heale, the Ukip branch chairman in Thanet, who once had links with the far right. Many UKIP members want to know how Mr Heale, a former prison officer who was once the National Front branch organiser in Hammersmith, was allowed into the party. In the row Mr Farage is backing Mr Heale.

So has Farage put his money where his mouth is and sued over such comments and coverage in the past? Or does he feel he would lose a libel case?
