The Queen has been pleased to appoint Prince William, The Earl of Strathearn, to be a Knight of the Most Ancient and Most Noble Order of the Thistle.
Appointments to the Order of the Thistle are entirely in the personal gift of The Queen and are not made on the advice of the Prime Minister, as are most other Honours.
The Most Ancient and Most Noble Order of the Thistle represents the highest honour in Scotland. Revived by King James VII, the Order has a complement of 16 Knights (KT). In 1987, The Queen decided that ladies should be eligible for the Thistle in the same way as men.
The Motto of the Order is Nemo Me Impune Lacessit (No one provokes me with impunity).
