Supercars of the super rich descend on central London

From Ferraris to Bugattis, supercars and their rich owners are back in London this summer.

Onlookers are lining up to have their pictures taken with the vehicles, but some Londoners who live in Knightsbridge say their roads are being turned into a racetrack.

BBC London's Alex Bushill spoke to car owner Riyadh Al-Azzawi and local resident Alexandra Morgan Thomas.
