The Observer published an apology for their article on Oct 23 on the death of Liam Lawlor. The apology is all about the 'sex' allegations: that Lawlor was in the company of a 'young prostitute' when he died and that he "'was known' to visit brothels and sex clubs in Prague".
What's not mentioned, however, is this sentence from the original report (now gone from the Observer's site): "Lawlor was suspected of recycling cash for criminals into property across western Dublin and latterly into eastern Europe". Does this mean that this allegation was more well-founded? And, I still say this is far more damning of Lawlor (and, probably, Kushnir by association) than anything about possible sexual activities.
