The royal couple joined the Irish Guards for their annual parade and celebration in Aldershot, about 40 miles southwest of London, on Thursday. The couple has not been able to take part in the occasion in recent years due to the COVID-19 pandemic. But they returned to the festive celebration this year, handing out symbolic shamrocks and joining in the festivities with the guards at their barracks.
