The Duke of Edinburgh is to miss a garden party at Sandringham tomorrow as he continues to recover from a bladder infection, Buckingham Palace said today.
Philip, who left hospital on Saturday - the day before his 91st birthday - will also miss the Queen's trip to the East Midlands on Wednesday.
The Duke fell ill following the Diamond Jubilee River Pageant, when he was on board the Spirit Of Chartwell royal barge in a flotilla of 1,000 boats along the Thames in extremely wet and cold conditions.
Philip's admission to King Edward VII Hospital in London meant he was forced to miss some of the key Jubilee weekend festivities.
Before falling ill after the pageant, Philip was due to be at the Queen's side for the garden party on the Norfolk estate.
The Diamond Jubilee event is being held to thank residents of Norfolk and Suffolk for contributing to community life.
The last time a garden party was held at Sandringham was in 2002 to celebrate the Queen's Golden Jubilee.
The Duke of York will stand in for his father and accompany the Queen.
