The Queen signed the Commonwealth's historic charter tonight despite still recovering from the symptoms of gastroenteritis.
Making her first official public appearance for more than a week she described the document as capturing "the core values and aspirations" of the family of nations, before putting her name to it.
The Queen was forced to miss the annual Commonwealth Day service this afternoon as she was still recovering.
But she looked well and in good spirits when she arrived at Marlborough House in central London, home of the Commonwealth, with the Duke of Edinburgh for the signing.
