British driver Jolyon Palmer is to leave the Renault team after Sunday’s Japanese Grand Prix.
Palmer, who has had a difficult season alongside Nico Hulkenberg, will be replaced by Spaniard Carlos Sainz, who has already been signed for 2018.
Sainz’s place at Toro Rosso will be taken by Russian Daniil Kvyat.
It is a reprieve for Kvyat, who was dropped for Frenchman Pierre Gasly last month but the two will be team-mates at the next race, the US Grand Prix.
