Britain is all set to celebrate the Diamond Jubilee celebrations of the Queen, commencing on Saturday and final preparations for the events for the next four days are going on in full swing across the country.

Ahead of the formal opening of the celebrations on Saturday, a full-fledged rehearsal of the carriage procession between Westminster Hall and Buckingham Palace by the armed forces and Household Divisions were conducted on the early hours of Friday.

"We are at the right stage that we need to be at - we don't want to peak too early but it's everything I expected them to achieve," the BBC reported the state ceremonial training officer for the Royal Navy, Warrant Officer Paul Barker as saying.

During the procession on Tuesday, the Queen and the Duke of Edinburgh will be accompanied by the royal family, the Prince of Wales and the Duchess of Cornwall, the Duke and Duchess of Cambridge and Prince Harry.

Over 1,000 vessels of various shapes and sizes will form a flotilla and sail along the Thames.

Thousands of spectators are expected to witness the events on Tuesday when the historic jubilee celebration procession takes place.

Prince Charles would charm millions by showing the never-seen videos of the royals' childhood ahead of the celebrations. BBC1 would be airing Charles' childhood memories of her majesty on Friday night.

During the hour-long tribute, filmed in the private quarters of several royal residences, the Prince dusts off home movies and recalls his fondest memories growing up with the monarch.

In the meantime, millions of Britons are expected to be on the move during the double bank holiday.

The first bank holiday on Monday will witness a historic BBC Concert at Buckingham Palace featuring a host of famous musical artists including Shirley Bassey, Elton John, Tom Jones and Paul McCartney.

The concert will be staged at the Queen Victoria Memorial in front of Buckingham Palace.

As the Royal Navy, Warrant Officer Paul Barker described, the event is all in all gearing up with a mixture of nerves and pride to sing in chorus, "God Save the Queen".

Take a look at the pictures of preparations across the UK:

Despite its reputation as a sprawling urban metropolis, a third of London is actually made up of parks and open spaces. The surprisingly green city has eight Royal parks: Regent’s Park (including Primrose Hill), Hyde Park, St James’s Park, Kensington Gardens and Green Park are all in the center city while Greenwich Park, Brompton Cemetery, Richmond Park and Bushy Park are further afield. All parks are free and host millions of Londoners and tourists each year.Reuters
