More than 30 members of the Royal Family joined some 2,300 invited guests for a service at St Paul's Cathedral to mark the Queen's official 80th birthday.

Prince William and Princess Beatrice outside St Paul's. Other in attendance included the prime minister, former PMs Baroness Thatcher and Sir John Major and faith leaders.

Lord Coe and Sir Cliff Richard arrive for the event. Prayers were said for the Queen's devotion to duty, Christian faith and long years of public service.

In his sermon, the Archbishop of Canterbury Dr Rowan Williams said "common loyalty to the monarch" had helped keep the country together.

Royal Family fan Terry Hutt was among the crowd to greet the Queen and Prince Philip after the service.

A lunch at Mansion House followed. The Queen met top chefs Bryn Williams, Nick Nairn, Marcus Wareing and Richard Corrigan who won a contest to create the menu.

The menu comprised smoked salmon with blinis, pan-fried turbot with cockles and oxtail, loin of roe venison and custard tart.

In a speech, the Queen thanked the thousands of people from the UK and all over the world who sent her letters and cards.
