Yesterday, the Queen made her first public appearance in a week as she signed the Commonwealth's historic charter to mark Commonwealth Day. She looked relaxed as she greeted the guests in attendance at Marlborough House in central London, and did not appear to be in discomfort. Earlier in the day, the monarch had been forced to cancel her attendance at the annual Commonwealth Day service - for the first time in 20 years - as she still displayed symptoms of gastroenteritis. This week's scheduled public engagements include a visit London's Tech City tomorrow and attending a chapel service on Thursday, but other members of the Royal Family will now take her place.
