CABLE TV viewers could have been forgiven for thinking they tuned into the Category III Playboy channel instead of the local English-language newscast the other day.

The occasion was the pair's last night on air in Hong Kong before leaving for newer pastures - a continuing trend at the fledgling network. Producers of the programme weren't ready for the on-air display of affection and, unable to break up the embrace, decided to play along with it and commentate. After all, as Meg said breathlessly, 'we're an item you know'.
