Prince William and Kate Middleton attended the St Patrick's Day parade at Mons Barracks in Aldershot to present sprigs of shamrocks to the officers and guardsmen of the 1st Battalion Irish Guards. Middleton also decorated the regimental mascot, an Irish Wolfhound named Domnhall, with shamrocks.
This annual ceremony dates back to 1901, when Queen Alexandra – wife of the then-king, Edward VII – requested shamrocks be given to the regiment on St Patrick's Day. Ever since then, a senior female member of the Royal Family has carried on the tradition.
Middleton wore a brown Catherine Walker coat and a Lock & Co hat, with a gold shamrock brooch given to the Queen Mother by the Irish Guards.
