Northamptonshire-based Force India have confirmed German driver Nico Hulkenberg will move to F1 rivals Renault next season.
The 29-year-old has been part of the team for the last five years, but has decided to end his contract in order to "explore fresh opportunities".
Force India will now have to find a replacement, with Manor Racing's Esteban Ocon and Pascal Wehrlein likely to be among the targets.
Everybody at Sahara Force India wishes Nico well as he embarks upon a different path in Formula One.
Having spent five years with us, Nico has become a great friend and contributed a huge amount to the team’s success.
He’s an outstanding driver, who has scored more points for this team than anybody else.
While it’s true we will miss Nico, we respect his decision to explore fresh opportunities and it would be wrong to stand in his way.
Stevenage driver Lewis Hamilton couldn't hide his anger with his Mercedes team after an engine failure denied him the chance to win the Malaysian Grand Prix.
Hamilton was cruising to victory before his engine blew up with just 15 laps remaining to hand the win to Red Bull's Daniel Ricciardo.
Nico Rosberg finished third to stretch his lead at the top of the drivers' championship to 23 points, and after the race a clearly agitated Hamilton appeared to accuse those in charge at Mercedes of favoritism.
"Someone doesn't want me to win this year," he told BBC Radio 5 Live.
"My question is to Mercedes. We have so many engines made for drivers, but mine are the only ones failing this year.
"Someone needs to give me some answers because this is not acceptable.
"We are fighting for the championship and only my engines are failing. It does not sit right with me."
