Renault have confirmed that the Japanese Grand Prix will be Jolyon Palmer's last with the team, with 2018 signing Carlos Sainz Jr. moving across to replace him for the final four races of the season.
Renault had been pushing for an early termination of Palmer's contract in order to run Sainz for the remaining races of the 2017 season. However the Briton refused, insisting he see out the year with the team.
On Saturday, Renault confirmed that the two parties had agreed by "mutual agreement" to split early.
"I would like to thank Jolyon for his commitment to the team and his professionalism," commented team boss Cyril Abiteboul.
"Since Renault’s return to Formula 1, Jolyon has been highly dedicated in an evolving environment. He has shown great personal qualities and we wish him all the best in his future career."
Palmer added: "The Japanese Grand Prix will be my last race for Renault. It’s been an extremely challenging season and I’ve been through a lot in the last three years, but it’s been a tremendous journey overall with the team.
"I can look back proudly at the performance in the second half of last season, my first point in Malaysia and of course reaching a career high of sixth place in Singapore this year.
"I wish the team all the best for the future. My immediate focus is now on achieving the best possible result in the Japanese GP, and then I can assess my options for the future."
Sainz will be replaced by Daniil Kvyat at Toro Rosso, with Pierre Gasly remaining.
