Jack Aitken has confirmed his departure from the Renault Formula 1 team as its test and development driver.

Aitken’s four-year association with the French manufacturer began following his Formula Renault Eurocup title win in 2015.

The championship earned him a place in Renault’s Driver Academy, where he would later graduate after a successful stint in GP3.

A step up to Formula 2 with ART followed in 2018, finishing 11th in his rookie season as team-mate and now Williams F1 driver George Russell claimed the crown.

Aitken signed for Campos Racing last year, finishing fifth in the overall standings with three race victories, including a win on home soil at Silverstone.

The Anglo-Korean driver was Renault’s test/development driver the past two years, but revealed he had split with the Enstone-based outfit.

“I would like to express my thanks to Renault and the Academy for helping me reach a position where I can now take a very exciting next step in my career which will keep me on course to fulfil my ambition of reaching the very top of motorsport,” Aitken posted in a statement on Twitter.

“I wish the Renault F1 Team and its drivers every success for the future.

“I am not yet in a position to announce my plans for the forthcoming season but stay tuned to my social media channels for all the latest news which should be made public very soon.”

Although no announcement has been made of Aitken’s plans for the 2020 season, he is expected to remain in F2 with Campos.
