LONDON: The Queen marks her 91st birthday today – her “real” birthday, as the monarch traditionally has two. Celebrations will be more subdued than last year, when her 90th was marked by national festivities. But she can still expect royal gun salutes from the King’s Troop Royal Horse Artillery and the Honourable Artillery Company at midday. The Queen is thought to be at Windsor Castle, where she traditionally spends a month-long residence, known as Easter Court. Her “official” birthday – marked by the Trooping the Colour ceremony – takes place in the summer. Today’s more low-key anniversary may suit the monarch, who is said to prefer practical gifts to overly extravagant ones. A washing-up apron and a casserole dish given to her by family members are among her most treasured gifts. Even so, she has received a variety of presents over the years.
