The Queen has said she is dedicating herself "anew to your service", as she marks the 60th anniversary of her accession to the throne.

英国女王登基60周年之际，她表示将致力于“重新为大众服务”。

In a message, she also said she felt "deeply moved" by the support shown for her Diamond Jubilee¹.

It will be marked by several events, with the main celebrations in June.

The Queen, 85, usually spends Accession Day - the day her father, George VI, died in 1952 - privately² but this year has two engagements in Norfolk.

This year's anniversary will be marked by visits to King's Lynn Town Hall and the nearby Dersingham Infant and Nursery School.

Crowds are expected to gather to greet the Queen, despite the cold weather.

Two official photographs were released, and a 41-gun salute³ will be held in Hyde Park, London, followed by a 62-gun salute at the Tower of London.

During her reign⁴, Queen Elizabeth II has seen 11 UK prime ministers come and go, with David Cameron her 12th.

Mr Cameron praised the "magnificent service" given by the Queen and called her a "source of wisdom and continuity".

"With experience, dignity and quiet authority she has guided and united our nation and the Commonwealth⁵ over six varied⁶ decades," he said.

One former Prime Minister, John Major, reflected on the counsel of the Queen and the many private meetings he had with her during his premiership during an interview on BBC One's Andrew Marr Show on Sunday.

He said: "Most of the present cabinet weren't born when the Queen became monarch⁷. So there's very little she hasn't seen, very little she doesn't understand. And anyone who doesn't listen to her view and consult her when necessary is missing a huge opportunity."

Meanwhile, Sir John has formally launched the Queen Elizabeth Diamond Jubilee Trust to help those in need across the Commonwealth.

He will chair the grant-making body, which will focus on areas such as fighting curable（可医治的） diseases and the promotion⁸ of education and culture.

A set of six 1st class definitive⁹ stamps, all of which feature official portraits of the Queen, are also being issued to mark the monarch's milestone¹⁰.

Moya Greene, Royal Mail's chief executive, said: "The Queen's image is one of the most recognisable in the world and we are delighted to bring these iconic（形象的） images together to mark the 60th anniversary of the Queen's accession."

The Diamond Jubilee Miniature Sheet marks the first occasion on which official images of the monarch, sourced from stamps, coins and banknotes, have been brought together for a stamp issue.

The Queen's 60 years as monarch are set to be marked by a series of regional, national and international events during 2012, culminating in a four-day long UK Bank Holiday weekend in June.
