Spanish driver Fernando Alonso has agreed to leave McLaren, the team has confirmed.
A statement released by McLaren confirmed that Alonso, a begrudging team-mate to Lewis Hamilton, has quit his contract with two years left to run.
"Following a meeting between Fernando Alonso and McLaren, it was agreed that it would be in the best interests of both parties to bring the relationship to an end," the statement said.
Also quoted in the statement, Alonso eluded to "ups and downs" through the season but bore no grudges as he departed.
"I know there have been suggestions of favouritism within the team and people say a lot of things in the heat of battle, but in the end I was always provided with an equal opportunity to win," he said.
Team boss Ron Dennis added: "In the end we reached a stage where none of us could find a way to move forward."
The mutual decision came at the end of three days of intense negotiations at the team's headquarters in Woking, Surrey.
The Spaniard finished a first fractious season with McLaren in third place, trailing the championship winner Kimi Raikkonen and team-mate Hamilton.
Alonso arrived from rivals Renault at the start of the season a two-time world champion but saw his place quickly challenged by the rookie Hamilton.
The split effectively makes Alonso a free agent ahead of next season.
McLaren said it would announce Hamilton's new team-mate "in due course".
