The retracted Newsnight allegations about a paedophile ring involving senor Tories followed on from allegation made by the MP Tom Watson in Parliament.
During the Damian McBride affair- in which Gordon Brown's aide was outed plotting to smear various Conservatives, usually by making up sexual rumours- some attention was paid to the role of Tom Watson.
Watson shared an office with McBride and was on good terms with the other man involved in the scandal- Derek Draper- but no emails emerged to prove Watson's involvement and he got a bit litigious when it was suggested that he was part of the scheme.
Yet it has to be said, his "exposure" of a paedophile ring linked to the Thatcher government does seem to have had a very similar effect to that which was intended by the McBride plot. A number of senior Conservatives have had false rumours spread about them online as a result of dark hints dropped by Watson (with the help of Newsnight) without any actual evidence.
It does make you wonder whether Tom Watson actually believed that there was substance to the paedophile ring which he referred to or whether he was using the Jimmy Savile scandal and parliamentary privilege as an opportunity to slime those on his enemies list.
