King Charles III and Queen Camilla are attending a church service at St George's Chapel in Windsor Castle as part of their Easter celebrations.
The traditional Easter Matins service is being held in the 15th Century chapel in Windsor, Berkshire.
Several members of the Royal Family are also present for the service, including the Princess Royal and the Duke of York.
Easter Sunday celebrations are taking place all around the world to commemorate the most important date in the Christian calendar.
Prince Andrew arrived with his ex-wife Sarah, Duchess of York, in a car along with Princess Anne and her husband Sir Tim Laurence.
Princess Anne chatted at some length with the Dean of Windsor, the Right Rev Christopher Cocksworth outside, while Prince Andrew quickly walked inside for the service.
But the many royal fans who gathered outside did not get to see the Prince and Princess of Wales, because they are spending the weekend with their children in Norfolk.
Prince William and Catherine also missed the service last year after Catherine - who is now in remission - was diagnosed with cancer.
On Thursday, the King and Queen took part in the traditional Maundy Thursday service, held this year at Durham Cathedral.
The service follows the King's Easter message, which sought to bring unity between different faiths and recognise those who provide humanitarian aid in wars and disasters.
"One of the puzzles of our humanity is how we are capable of both great cruelty and great kindness," he said.
Later today, the Easter sermon traditionally given by the Archbishop of Canterbury and seen as the Church of England's primary religious message for the weekend, will instead be delivered by the Archbishop of York at York Minster.
Justin Welby, the former Archbishop of Canterbury, resigned in November after facing increasing pressure to stand down over his failure to report prolific child abuser John Smyth. But his replacement has not yet been appointed.
The Archbishop of York, Stephen Cottrell, has also faced calls to resign over his handling of the case.
On Saturday, the leader of the Roman Catholic Church in England and Wales prayed for those caught up in "endless conflicts" and wars around the world in his Easter Vigil homily.
Archbishop of Westminster, Cardinal Vincent Nichols, said: "We pray for peace. We pray especially for those about whom it has been said, in recent times, that 'all hell' will be unleashed on them. May that never be so!"
