Diamond Jubilee: Final preparations under way
Union jacks and bunting are being put out across the UK, as final preparations are made for the weekend's Diamond Jubilee celebrations.
Earlier, a rehearsal of Tuesday's carriage procession between Westminster Hall and Buckingham Palace took place.
And crews of the 1,000-strong flotilla that will escort the royal barge along the Thames on Sunday were briefed.
Events are planned across the UK over the next four days to mark 60 years since the Queen came to the throne.
Last-minute preparations are under way for the many street parties, outdoor concerts and fairs being staged for the royal celebration:
- The Royal Navy warship HMS Diamond marked the start of celebrations with a 21-gun salute in Portsmouth
- The Woodland Trust released a list of 60 new, large woodland areas designed to celebrate the Queen's reign
- Archbishop of Canterbury Dr Rowan Williams issued a video tribute to the Queen, praising her sense of humour
- Final preparations for the Jubilee concert got under way, with a stage constructed on the roof of Buckingham Palace, where pop band Madness will perform their hit Our House
- Services are running on nearly all London Underground lines at the weekend but Transport for London advises people to check before they travel
- The weather forecast is expected to be poor for the official celebrations in central London
In the early hours of Friday, members of the armed forces and the Household Division were among the 2,000 servicemen and women rehearsing the carriage procession - one of the final events of the Jubilee celebrations.
Thames pageant preparations
Under the gaze of some of London's biggest skyscrapers, an eclectic collection of boats, ships and kayaks are gathering for what one captain has described as a "uniquely British event".
The noise of chugging engines at West India Dock and the occasional seagull is broken by the excited conversations of the boat crews anticipating Sunday's events.
Those on board are busily attaching a collection of multi-coloured flags, including a special Jubilee ensign, and even touching up the paint work on their largely immaculately turned out boats.
Among them will be the Dunkirk Little Ships - famed for rescuing thousands of troops in World War II. They will hope to bring some of their celebrated spirit to the Thames on Sunday.
Roads in central London were closed off for the rehearsal of Tuesday's carriage procession, which ended at 06:00 BST.
Members of the Household Cavalry Mounted Division rode from the Palace of Westminster along Whitehall to Trafalgar Square, before travelling along the Mall to Buckingham Palace.
The procession included the 1902 state landau carriage - used by the Duke and Duchess of Cambridge on their wedding day - which will be used to take the Queen and the Duke of Edinburgh from a thanksgiving service at St Paul's Cathedral on Tuesday.
The BBC's Daniela Relph said the full ceremonial rehearsal had been a display of the pomp and pageantry expected during the Jubilee celebrations.
Soldiers rehearsed their three cheers for the Queen and the national anthem was played, she added.
Major Andrew Chatburn, the ceremonial officer for the Household Division, said the rehearsal had been "spectacular".

Meanwhile, the Archbishop of Canterbury has paid tribute to the Queen, who he describes as being "unfailingly supportive and kind".
Rowan Williams, who will step down as Archbishop in December after 10 years, said in a video that during private meetings, he discovered that Her Majesty is "extremely funny and prepared to be teased", and helped him through difficult periods of his own life.
