A week before Trooping the Colour, excitement is mounting among royal fans.

The occasion transforms the Mall as crowds line up the streets waving flags as 1400 soldiers parade alongside 200 horses and 400 musicians from Horse Guard's Parade to Buckingham Palace.

Many fans treat today as a stirring preview of the majesty to come. The Colonel’s Review, a dazzling full-dress rehearsal steeped in pageantry, unfolds in central London, offering a taste of the splendour that will accompany His Majesty the King’s official Birthday Parade next week.

In their ceremonial uniforms, the British Army’s finest soldiers march with precision and pride as they rehearse for one of the most iconic events in the royal calendar.

Trooping the Colour is a centuries-old tradition that marks the Sovereign’s official birthday.
