Troops will start forming up on Horse Guards Parade imminently.

The BBC’s coverage will begin just over an hour later, at 10.30am.

At around 10.45am, King Charles will leave Buckingham Palace escorted by the Household Cavalry for the traditional procession.

Like last year, His Majesty is not expected to travel on horseback for the journey to Horse Guards Parade.

Instead, he will make the journey in a carriage.

At 11am, King Charles will arrive at Horse Guards Parade to take the royal salute and inspect the troops.

In line with decades of tradition, the ‘colours’ will then be carried down the ranks and showed to the soldiers.

At around 12.20pm, the carriage carrying King Charles will lead his troops back to Buckingham Palace via The Mall.

At the gates of the Palace, he will watch the parade march past and give a second salute.

Shortly after 12.50pm, soldiers from the King’s Troop, Royal Horse Artillery, will fire a 41-gun salute in Green Park to celebrate the monarch’s official birthday.

Then, at around 12.55pm, King Charles and other members of the Royal Family will make the traditional appearance on the Buckingham Palace balcony.

The celebrations will then conclude with a stunning Royal Air Force fly past featuring various planes and helicopters.

Well-wishers are already lining the streets in anticipation of Trooping the Colour, and the pictures are brilliant.

With the flag of Wales hung over the fence, this group have even brought a cutout of the country’s Princess with them!

Joining them in cutout form is none other than King Charles.

The honour to Troop their Colour rotates between five regiments of the Foot Guards.

This year it is the turn of Number Seven Company of the Coldstream Guards.

It will mark the first time that the Coldstream Guards have trooped their colour in front of the King.

And it is fitting given that His Majesty presented new Colours to the Coldstream Guards only yesterday to mark the regiment’s 375th anniversary.

Some fantastic images are coming into us now as things begin falling into place for today’s celebrations.

First up we’ve got The Mall decked out in Union flags, followed by some extraordinary pictures of The Coldstream Guards at Windsor Castle.

Then we’ve got some images of King Charles looking joyous as he inspects the Guards as they line up in west London.

Trooping the Colour has marked the official birthday of the British Sovereign for over 260 years.

It was decided in 1748 that the parade would be used to mark the official birthday of the monarch and became an annual event after King George III acceded to the throne in 1760.

Over 1,400 soldiers, 200 horses and 400 musicians come together each year in a display of military precision, horsemanship and fanfare to mark the occasion.

Thousands of spectators line the streets to watch the parade which is traditionally followed by the annual RAF flypast and the Roya Family’s iconic balcony appearance.

The streets are lined with crowds waving flags as the parade moves from Buckingham Palace and down The Mall to Horse Guard’s Parade, alongside Members of the Royal Family on horseback and in carriages.

The display closes with an RAF fly-past, watched by Members of the Royal Family from Buckingham Palace balcony.

King Charles has ordered royals to wear black armbands in rememberance of those killed in the Air India plane crash for Trooping the Colour today.

The monarch has requested a minute’s silence in tribute to the 241 passengers and crew killed when a Boeing 787 Dreamliner bound for Gatwick Airport came down on Thursday in the Indian city of Ahmedabad.

Black armbands will be worn by the head of state and senior royals riding in the ceremony to mark the King’s official birthday.

The King issued a written message soon after the plane crash saying he was ‘desperately shocked by the terrible events’ and expressed his ‘deepest possible sympathy’.
