London, Sept.29 : A rude gesture by one of Queen Elizabeth II's guards last night left visiting tourists outside Buckingham Palace shocked, and him in trouble.
According to The Sun, the guard's hand signal was videoed by an American sightseer and posted on the website YouTube.
The sentry is seen moving his clenched fist up and down, apparently in a joke insult to a comrade.
Palace guards are strictly forbidden from communicating with anybody while on duty.
