The Duchess of Cornwall lent her support to Queen Elizabeth during the 94-year-old monarch’s first public appearance following Prince Philip’s departure from hospital after his recent heart surgery.

Her Majesty was joined by her daughter-in-law during a Zoom call held in honour of the U.K.’s NHS volunteers, who have been helping in the ongoing fight against COVID-19.

Praising volunteers for their contribution during the pandemic, the Queen said, “I think it’s wonderful work and I do thank everybody for, and all the others too, who have been volunteering. It’s been a great, great help, over this very difficult year. Very nice to meet you all.”

The Queen was reunited with her 99-year-old husband on Tuesday after he was released from King Edward VII’s Hospital in London.

Philip was first admitted to hospital on Feb. 16 to receive treatment for an unspecified, but not COVID-19-related, infection.

The duke underwent a procedure for a pre-existing heart condition earlier this month.

“His Royal Highness wishes to thank all the medical staff who looked after him at both King Edward VII’s Hospital and St Bartholomew’s Hospital, and everyone who has sent their good wishes,” said Buckingham Palace in a statement shared with ET Canada
