It has been a turbulent year for the Royal Family. Since the last Trooping the Colour, we have seen the scandal around the King's brother Andrew Mountbatten-Windsor widen and more questions being asked around royal properties and finances.
But today is very much the traditional display of royalty - showcasing pomp and ceremony and the role of the King as head of the armed forces.
A group of protesters holding up signs saying 'Not My King' and 'Down with the Crown' can be seen in the crowds on The Mall
Some protesters are holding bright yellow placards reading "Not My King" - and that's also what they're chanting.When the troops pass by, they seem to shout louder.
They're also holding up photos of Andrew Mountbatten-Windsor, the King's brother, who was stripped of his royal titles over his connections to convicted sex offender Jeffrey Epstein.
Protesters hold placards showing the former Prince Andrew and late US sex offender Jeffrey Epstein during the Trooping the Colour. The anti-monarchy group, Republic, is protesting at Trooping the Colour today as it has in previous years.
The group says it is a public event and it has every right to peacefully protest in front of Buckingham Palace.The Metropolitan Police say they have a policing plan in place to ensure Trooping the Colour passes off safely and peacefully, including minimising disturbance to horses taking part.
And the police also say they are "working with protesters to ensure we can balance these needs with their right to lawfully protest”.
The King and Queen are now leading a procession back up The Mall to Buckingham Palace, where a further salute will take place.
Then at 13:00 BST, members of the Royal Family will watch the Red Arrows flypast from the balcony at the palace.
