COMMEMORATIVE stamps are being issued to mark the 60th anniversary of the launch of the Royal Yacht Britannia.

The book of 10 Royal Mail first-class stamps feature images of the yacht, built on the Clyde and now moored in Leith, being launched by the Queen in 1953. Her apartments and final overseas trip to Hong Kong in 1997 will also be portrayed.

During its 44 years serving the royal family, the boat sailed on 968 official voyages around the world and is believed to have travelled more than a million miles.

The yacht's barge led the Thames Jubilee pageant last June, carrying the Queen and the Duke of Edinburgh.

Built by workers at the John Brown shipyard in Clydebank, near Glasgow, she was launched on the Clyde on April 16, 1953. She is now attracts around 300,000 visitors a year.

The stamps are on sale from Tuesday, exactly 60 years since the Clyde launch.

Royal Mail spokesman Andrew Hammond said: "It's only fitting that HMY Britannia's anniversary should be marked with a set of Royal Mail commemorative stamps that will travel the world in the same way the yacht did for so many years."
