(CNN) -- Members of the royal family, UK government and dignitaries gathered Tuesday in Westminster Abbey for a service to mark the 60th anniversary of Queen Elizabeth II's coronation.

The queen was accompanied to the service by her husband, Prince Philip, as well as her grandchildren, Princes William and Harry.

William's pregnant wife Catherine, the Duchess of Cambridge, was also present. She is expecting their first child in July, just over two years after they were married at the abbey.

Prime Minister David Cameron gave a reading as the service began amid pomp and ceremony.

The queen acceded to the throne in 1952, but her formal coronation took place on June 2, 1953.

Archbishop of Canterbury Justin Welby in his reading praised "60 years of commitment" since the day the monarch was crowned.

Diamond Jubilee celebrations were held last year to mark her 60 years on the throne.
