Queen's grandson to marry
Peter Phillips, the Queen's eldest grandson, will marry Autumn Kelly in St George's Chapel at Windsor Castle.
The couple, both 30, will exchange vows at the chapel before hosting a reception at Frogmore House, which has been lent to them by the Queen.
The ceremony is likely to see a large royal turnout but one absentee will be Prince William, who is said to be attending a friend's wedding in Africa.
