The Crown Equerry is the operational head of the Royal Mews of the Royal Household of the Sovereign of the United Kingdom. He is responsible for the provision of vehicular transport for the Sovereign, both cars and horse-drawn carriages. Train travel is arranged by the Royal Travel Office, which also co-ordinates air transport.
The position of Crown Equerry should not be confused with that of the Equerry: although both are nominally under the Master of the Horse, equerries are effectively independent, performing distinct tasks, and are personal assistants to the Sovereign and senior members of the Royal Family.
