Queen message in Jubilee programme
The Queen and the Prince of Wales have written personal messages in an official Diamond Jubilee souvenir programme.
The publication is designed to provide an insight into the Queen's life and reign and will go on sale in far-flung locations - including Australia, Singapore and South Africa - as well as across Britain.
In her message, the Queen writes: "This memorable year will serve to remind us of the importance of family and friendship, examples of which my family and I have been fortunate to see in many forms during our Jubilee travels throughout the United Kingdom and the wider Commonwealth.
"It will also be a time to give thanks for the many achievements of the last six decades and to look to the future as we join together in our celebrations."
In his message, the Prince of Wales reflects on the Queen's "extraordinary contribution to British public life".
He writes: "Her Majesty's life and work have given a powerful expression to those cherished qualities of selflessness and duty which, in so many ways, have helped to transcend the immense changes in the last six decades."
The souvenir publication, which was produced with help from the Royal Household, recalls the splendour of previous royal jubilees. It also contains an illustrated guide to the key events over the four-day bank holiday weekend.
A portion of its proceeds will be donated to The Queen Elizabeth Diamond Jubilee Trust which raises funds for projects designed to make a difference to people's lives.
It will be available in the UK at retailers including Tesco, Sainsbury's, WHSmith, Waitrose and Asda. During the Jubilee weekend, it will also be on sale in London's Hyde Park and St James's Park.
Abroad, it is to be sold in Australia, New Zealand, Canada, France, USA, Italy, Belgium, Norway, Cyprus, Malta, Hong Kong, Singapore and South Africa.
