NICE to see that Michael Beloff QC is keeping himself busy with some interesting court cases at home in England while he's not acting for China Light and Power following the fatal power station explosion in Hong Kong. Mr Beloff has been employed by Gillian Taylforth - actress in the popular EastEnders soap opera - and her fiance Geoff Knights to help sue The Sun newspaper for alleging that she and her fiance were caught in a compromising position on a road in Hertfordshire in southern England. Court reports from the trial last week quoted the couple as saying they had stopped because Mr Knights was suffering from pancreatitis; he had loosened his trousers and she had placed her hand on his abdomen to ease the pain. Mr Beloff is quoted as suggesting to PC Terence Talbot, who claimed he discovered the couple in an indecent act (and in our opinion should merely have looked away politely and walked on): ''You jumped to a false conclusion because you saw the open trousers on the man and the woman leaning over . . . and you thought, impetuously and wrongly, that you had seen some kind of sexual act.'' However, PC Talbot told the High Court libel jury that if he stayed in the witness box ''until Christmas'' he would not change his evidence that he found the pair engaged in an act of oral sex in a Range Rover. It must be a bit of a blow to Mr Beloff that he has to leave this glamorous world of British TV stars to return to Hong Kong for a judicial review into the verdict returned by the inquest jury on the deaths of the two China Light and Power men. Readers may recall that this case revolved around a rather different kind of Blue Report.
