The Queen has returned to royal duties just four days after the death of her husband, the Duke of Edinburgh. On Tuesday, the 94-year-old monarch hosted her first in-person event since Philip's passing on Friday to mark the retirement of her household's most senior official, former Lord Chamberlain Earl Peel. Her return to work comes as preparations are under way for Philip's funeral, which will feature servicemen and women from the Royal Navy, Royal Marines, Army and RAF - alongside top military brass - this Saturday at Windsor Castle. It was announced at the weekend the monarchy and their households would observe two weeks of royal mourning, with members of the family "continuing to undertake engagements appropriate to the circumstances," a royal official said. The Earl Peel had overseen arrangements for the duke's funeral - known as Operation Forth Bridge - before handing responsibility to his successor, former MI5 spy chief Baron Parker, just over a week before Philip died peacefully at Windsor Castle.
