The Queen marked her Golden Jubilee with the first-ever ecumenical church service at St George's Chapel, Windsor, yesterday.

On the 49th anniversary of her Coronation, the Queen witnessed four church leaders sign an historic covenant to work towards furthering Christian unity.

Some 2,000 people turned out to see the Queen and the Duke of Edinburgh at the servicee.

At the invitation of the Queen, Archbishop of Canterbury Dr George Carey was joined by Roman Catholic Archbishop of Westminster Cormac Murphy-O'Connor, Free Churches Moderator the Reverend Anthony Burnham and the Reverend Esme Beswick, of the Anglo-Caribbean Council of Churches, to take part in the service.

The Queen looked on as they signed the covenant on Christian unity, which commits each of the church leaders to pray, work and consult together, and join together to work for justice.

It could have been a sombre occasion for the Queen as she returned to the Chapel where earlier this year the body of her mother and ashes of her sister, Margaret, were laid to rest.

But she appeared upbeat and enjoying her jubilee celebrations.

In his sermon, Dean of Windsor the Right Reverend David Conner praised the Queen for her "continuing commitment, dedication, total loyalty and unstinting service to the church, the nation and the Commonwealth".

After the service, the Queen and Duke went on a walkabout in the grounds and chatted to the large crowd of well-wishers.

Nearly 3,000 people lined the streets of Swansea yesterday to catch a glimpse of the Prince of Wales and his two sons as they attended a service to commemorate the Queen's Golden Jubilee.

Princes William and Harry elected to join their father at the service despite its clash with England's first game of the World Cup. After the hour-long service, the three princes spent 20 minutes talking to members of the public who had waited for more than three hours
