The monarch – who turns 95 this month – hosted a retirement ceremony Tuesday at Windsor Castle in honor of Earl Peel who stepped down as Lord Chamberlain a week before Prince Philip died, according to the Court Circular. "The Earl Peel had an audience of The Queen today, delivered up his Wand and Insignia of Office as Lord Chamberlain and the Badge of Chancellor of the Royal Victorian Order and took leave upon relinquishing his appointment as Lord Chamberlain, when Her Majesty invested him with the Royal Victorian Chain," the daily record of public duties of the British monarchy says. PA Peel's duties are being taken over by former MI5 spy chief Baron Andrew Parker. Prior to Peel's retirement after 14 years in the Lord Chamberlain position, he was overseeing the Duke of Edinburgh's funeral proceedings. The funeral will be at St. George's Chapel at Windsor Castle at 3 p.m. U.K. time (10 a.m. ET) and will be broadcast live. The first details were confirmed at a briefing held by palace officials on Saturday. Prince Philip and Queen Elizabeth. Tim Graham/Getty Images Can't get enough of PEOPLE's Royals coverage?
