The British Grand Prix is a Grand Prix motor race organised in the United Kingdom by the Royal Automobile Club. First held in 1926, the British Grand Prix has been held annually since 1948 and has been a round of the FIA Formula One World Championship every year since 1950. In 1952, following the transfer of the lease of the Silverstone Circuit to the British Racing Drivers' Club, the RAC delegated the organisation of the race to the BRDC for the first time, and this arrangement has continued for all British Grands Prix held at Silverstone since then (organisation of British Grands Prix held at Aintree having meanwhile been similarly delegated to the British Automobile Racing Club).
