Cadets were honoured to be part of an historic day as HRH the Duke of Edinburgh attended his final public engagement at Buckingham Palace.
Ten royal marines cadets from Waltham Forest, Haringey, and Hornchurch and Upminster detachments were at the 1664 Global Challenge Parade this afternoon.
The event was the final one which HRH the Duke of Edinburgh will attend in an official capacity, having completed 22,219 solo engagements since 1952.
Sea Cadets would like to wish His Royal Highness a very happy retirement.
