Her Majesty The Queen has presented new colours to the 1st Battalion Welsh Guards, as they celebrate the regiment’s centenary.
She was joined by The Duke of Edinburgh, The Prince of Wales and the Duchess of Cornwall at Windsor Castle, where the ceremony was followed by a garden party in the grounds.
The Queen cited the regiment's "indomitable family spirit" calling it their "hallmark".
The infantry units of the British Army each have two Colours; the Queen's Colour, which is a union flag and symbolises the regiment's loyalty to the Crown, and a regimental Colour which has all the unit's battle honours inscribed on it.
