Household Division troops pulled off a masterclass in discipline, detail and teamwork as the Coldstream Guards trooped their colour in the year they celebrate their 375th anniversary.
The unit, pictured above, is the army’s oldest continuously serving regiment.
More than 1,000 soldiers and 200 horses took part in the day, carrying out complex battlefield drill manoeuvres to a programme of specially composed music.
The spectacle concluded with a flypast over Buckingham Palace.
