The Duchess Of Cambridge
is to accompany her husband to Edinburgh next month when the Queen makes Prince William
a Knight of the Thistle - one of her highest orders of chivalry.
The honour will mark William's 30th birthday next Thursday, with a ceremony taking place at St Giles' Cathedral on July 5. The Duchess Of Cambridge
, pictured, will attend. The couple are known as the Earl and Countess of Strathearn in Scotland.
