We hope you enjoyed following along with us - we're going to finish up our coverage and get out into the sunshine ourselves.

Here's what we've seen today:

• King Charles III flanked by Prince William, Prince Edward and Princess Anne on horseback, and followed by Queen Camilla and Catherine in a horse-drawn carriage, inspecting the assembled troops and receiving the royal salute

• A 41-gun salute in Green Park

• Helicopters, Battle of Britain aircraft, typhoon fighter jets and the Red Arrows in a huge flypast as the royals watched from the Buckingham Palace balcony - with aircraft forming the initial CR - for Charles Rex - in the sky

You can see the best of the day in pictures here.

And if you check back on our home page shortly, you'll find a video of the best bits.

Goodbye, and have a lovely afternoon!

When the King stepped back inside from his balcony he must have had a sense of relief, after a morning when everything went to plan.

His horse might have been a little skittish at the start, but the choreography of the day went with spectacular precision.

It was picture postcard stuff in the summer sunshine.

This is part of the annual calendar of big royal events and for the first time it was with King Charles in the leading role.

It was a point even made in the thundering fly-past, with RAF jets marking out CR - Charles Rex, Latin for King - in the London skies.

But there might have been a moment of poignancy for him too.

A year ago, at the Platinum Jubilee, it had been his mother on the same balcony, appearing before the crowds. Much has happened for him in the year since then.

Our team outside Buckingham Palace have spoken to a few people who came to watch today's events.

With a fly-past you really feel the moment as well as see it. There’s that sound of planes approaching and then the ground-shaking moment as they race overhead.

You don’t have to be a planespotter to enjoy the spectacle and the crowds outside Buckingham Palace were lapping up the waves of different formations.

The sight of fighter jets forming up the letters CR - for Charles Rex - in the sky was a particular crowd-pleaser.

It must have been a great view from the balcony - and as the vapour trails faded, the King waved and disappeared back inside.

The iconic Red Arrows aerobatic team have rounded off the flypast, leaving red, white and blue trails in their wake - with cheers from the crowd as the national anthem plays and the King waves from the balcony.

Earlier we were told that the flypast contained a secret formation as a surprise for the King.

We should have guessed it really - 18 aircraft have just flown overhead forming the initials CR - for Charles Rex.

The two Hurricanes, one Lancaster and one Spitfire have now passed over the palace, as King Charles and the other senior royals crane their necks upwards to watch them.

The first of at least 70 aircraft in the flypast are now approaching Buckingham Palace.

First are a series of helicopters, including Wildcast Apache and Chinook Puma.

These will be followed by the Battle of Britain Memorial Flight's Lancaster, Spitfire and Hurricane planes.

Then we'll see three C-130 Hercules - this is the final ceremonial flight of the transport plane, which has been used by the RAF since the 1960s.

Next come an array of modern military planes, including Typhoon fighter jets.

The King and senior royals have now emerged onto the balcony at Buckingham Palace - including Prince William and Kate's children - Princes George, Princess Charlotte and Prince Louis.

A huge cheer could be heard as they appeared and begin to wave, ahead of the flypast which is due to begin.

In five minutes' time, there'll be a huge flypast of 70 aircraft over Buckingham Palace. The scale of it will make up for the one that was scaled back at the Coronation because of bad weather.

If you don't know your Chinooks from your Typhoons, or your Spitfires from your Hurricanes, this guide put together by our graphics team might come in handy.

Remember we've also been promised a "very special signature formation" which has been kept under wraps as a surprise for the King.

The King’s Troop Royal Horse Artillery are firing 41 rounds - 21 with marks the monarch's birthday, and another 20 because it is taking place in a Royal Park.

The rounds will be fired at ten second intervals, which will take six minutes - leading up to the flypast over Buckingham Palace at 1300.

There will also be a 62 gun salute at the Tower of London.

Street cleaners following the parade got a very good reception from the crowd – and they responded with some appropriate royal waves.

They really milked the moment, and why not?

With the parade over, police are now leading thousands of spectators towards Buckingham Palace, where the King will appear shortly.

While we're waiting for the flypast, here's a look back to the start of the parade.

Princes George and Louis and Princess Charlotte travelled down The Mall in a carriage with their mother, the Princess of Wales, and Queen Camilla.

The King’s horse seems to have calmed down from looking a little lively earlier. Maybe it prefers this upbeat marching music being belted out as the parade returns.

They’re now back at Buckingham Palace, trotting and marching past the newly-dug flower beds, which seem to have their own military precision. The lawns look trim enough for a match at Wimbledon.

And members of the Royal Family are soon to take their places on the palace balcony, with a great view of this lavish spectacle.

When there’s been talk of a “slimmed-down monarchy” it might seem a bit lavish for the monarch to have two birthdays in the same year.

But the simple explanation is the weather.

While the King’s actual birthday is in November, he has followed the tradition of holding the official celebration in the summer, when there’s a better chance of good weather for the birthday parade in central London.

Even though the watching crowds might enjoy the sunshine, it might be more of a mixed blessing for some of those taking part in the heat.

The main Trooping the Colour ceremony is now over, but stay with us as there's more to come.

The royals are on their way back to Buckingham Palace, where they'll barely have time for a cup of tea and a sit down before it will be time to appear on the all-important balcony.

They - and the crowds gathered nearby - will be treated to the spectacle of a 70-aircraft flypast at 13:00, just after a 41-round gun salute from nearby Green Park.

This is another display of the core of the current Royal Family, the “working royals” who will be most visible in the reign of King Charles.

At its centre are the two couples – King Charles and Queen Camilla and Prince William and Catherine.

Prince Edward and Sophie, now the Duke and Duchess of Edinburgh, have an increasingly prominent role.

But it also highlights those who are outside that inner circle, such as Prince Harry and Meghan, no longer “working royals” and not part of this event.

The Colour has been held low in a solemn moment as the ceremony draws to a close.

King Charles - flanked by the other senior royals - now moves to the head of his guards for the procession back to Buckingham Palace.

Then, preceded by the Household Cavalry, the Massed Bands will lead the royal procession along The Mall.
