The Duke of Edinburgh , who will be 92 next week, accompanied the 87 year old Queen to a service in Westminster Abbey yesterday, to mark the 60th anniversary of the coronation, despite having to cancel an engagement the night before as he was feeling unwell. In fact in the last eight months he was hospitalised twice with a bladder infection, and had to spend Christmas in hospital with a heart condition.
In March the Queen was also forced to cancel a number of public appearances after she was taken ill with gastroenteritis.
Their eldest grandson said it should come as no surprise if they are forced to cancel some future engagements.
Today the Queen invested The Duke of Edinburgh with New Zealand's highest honour, the Order of New Zealand, at Buckingham Palace.
