Someone has put the wind up the Black Watch - and it has nothing to do with this week's arrival of the People's Liberation Army. As trained sniper Lance Corporal Lee Wotherspoon went about the regiment's daily ceremony of lowering the flag at the Cenotaph, he was caught in the sights of a photographer just as a gust of wind had the bare-faced cheek to reveal what a Scotsman wears under his kilt. Yesterday, his commanding officers revealed there were no rules governing the wearing of underwear in the famous Highland regiment, and certainly no way of knowing how many of its ranks choose fresh air to Y-fronts. However, Regimental Sergeant Major Alan McEwen nailed his colours firmly to the mast: 'I certainly always wear underwear.' 'As for the other lads, I wouldn't want to go into percentages because I don't know. 'It's a matter of preference'. However, in a nod to the regiment's centuries-old no-underwear tradition - when officers checked to make sure the men had nothing under their kilts - today's officers and men still face a fine of a bottle of port if they are found to be wearing anything beneath their sporrans at mess functions. Captain Alistair Aitken said: 'There are no hard and fast rules. 'Since we came here, we have discovered that the press have an obsession with taking a photograph up the Jocks' kilts. It looks like they have had their first success.' The Black Watch Regiment arrived in Hong Kong in February as the last British battalion to serve here before the handover. Its soldiers guard the military bases and perform ceremonies, including the dawn and sunset raising and lowering of service flags at the Cenotaph.
