LONDON (AP) - Tributes poured in to Queen Elizabeth II on Monday as she marked 60 years on the throne with a message vowing to continue serving the British people.
Dressed in a Tiffany-blue hat and colorful overcoat against the winter cold, she was greeted by well-wishers in the snow-covered town of King's Lynn at an event planned to mark Accession Day, the anniversary of the day she became queen in 1952.
"I love that the monarchy is above politics and feel that the queen represents that best of all," said Laura Skrzynski, a longtime admirer of Elizabeth who joined the crowd of about 150 people applauding the queen's arrival. "She stands for integrity and respect and I am inspired by her faith. She has been a constant through all our lives."
Accession Day is usually marked quietly because it also marks the anniversary of the death of Elizabeth's father, King George VI. But it drew extra attention Monday because this year marks the queen's Diamond Jubilee celebration. Only Queen Victoria had a longer reign.
Elizabeth said in a message to mark the occasion that she and her husband, Prince Philip, have been "deeply moved" to receive so many kind messages about her Diamond Jubilee.
"I am writing to thank you for the wonderful support and encouragement that you have given to me and Prince Philip over these years," she wrote in a message to the nation. "In this special year, as I dedicate myself anew to your service, I hope that we will all be reminded of the power of togetherness and the convening strength of family, friendship and good neighborliness, examples of which I have been fortunate to see throughout my reign."
Prime Minister David Cameron of Britain praised the queen's "magnificent service," thanking her for guiding the nation with "dignity and quiet authority."
"Always dedicated, always resolute and always respected, she is a source of wisdom and continuity," Cameron said. "All my life, and for the lives of most people in this country, she has always been there for us. Today, and this year, in the 60th anniversary of her reign, we have the chance to say thank you."
The queen's Diamond Jubilee will be marked with a series of regional, national and international events throughout 2012.
Over the course of 2012, members of the royal family - including Prince William and his wife, the Duchess of Cambridge - will fan out across the globe and travel to Commonwealth countries including Canada, Jamaica and Belize.
The queen and Philip, also known as the Duke of Edinburgh, will stay closer to home, touring the U.K. from March to July. Philip, 90, was recently diagnosed with heart problems that may affect his future travel plans.
The 2012 Diamond Jubilee weekend will be held June 2-5, with the main highlight likely to be a huge pageant on the River Thames featuring a 1,000-strong flotilla. A gala concert is also planned.
Elizabeth expressed hope that the coming year will be a time to give thanks "for the great advances" since she took the throne and "look forward to the future with a clear head and warm heart."
