Seldon was on the Advisory Council of the Libertarian Alliance, one of whose leaders described Demos as:
- 'a cavalry of Trojan horses within the citadel of leftism. The intellectual agenda is served up in a left wing manner, laced with left wing cliches and verbal gestures, but underneath all the agenda is very nearly identical to that of the Thatcherites.'()
He co-authored Socialism Explained with Brian Crozier for Margaret Thatcher as part of their anti-left project. He also edited the Goldsmith-funded Radical Society's Journal, founded by Stephen Haseler and Neville Sandelson who both took part in attacks against the (UK) Labour Party. ()
Haseler worked for the 'left-face' of the US National Strategy Information Centre (NSIC)one of the funders of Brian Crozier's Forum World Features, a CIA front. He co-authored Eurocommunism with the NSIC's Roy Godson, who 'helped Oliver North channel contributions from private donors to the contras by using the Heritage Foundation to launder the funds'. () Haseler has written for Demos.
