The Duke of Edinburgh continued with his official engagements on Tuesday, despite undergoing an operation on his hand the day before.
The Queen's 88-year-old husband underwent day surgery on his left hand on Monday to treat carpal tunnel syndrome, a common condition that causes pain, numbness and a burning sensation in the hand and fingers.
But with his left hand bandaged he was back the following day, meeting guests at a reception at the Canadian High Commissioner's residence in central London.
Although the Duke – who turns 89 on Thursday – is trying to fulfil all his London engagements, the procedure has caused him to cancel a birthday trip to Crewe alongside the Queen.
The journey would have required him to stay overnight on the royal train and spend a long day on his feet.
