Prince William, the second in line to the British throne, has been appointed a garter knight by the Queen.
"The Queen has been graciously pleased to appoint His Royal Highness Prince William of Wales to be a Royal Knight Companion of the Most Noble Order of the Garter," Buckingham Palace said in a statement.
Founded by Edward III in 1348, the Order of the Garter is the highest and the oldest British Order of Knighthood.
With his appointment, William has become the 1,000 Garter Knight. His father, Prince Charles was made a Knight in 1958 and his grandfather Prince Philip, the Duke of Edinburgh, was appointed in 1947.
However, Prince William will be officially installed as a Royal Royal Knight Companion of the Order Garter by the Queen during a private service at Windsor Castle sometime in the month of June, the British media reported today.
Afterwards, he will take part in a public parade wearing his blue velvet robes and black velvet plumed hat for the first time.
Although the honour is merely a ceremonial one, it is, nonetheless, a significant step for the future king who will leave the military next January to become a full-time working royal.
A spokesman for Clarence House said "William is delighted and honoured at the appointment".
