Former Manor Marussia team principal John Booth has joined Toro Rosso as the Italian squad’s director of racing.
Booth led Marussia's F1 effort from its entry in 2010 until late last year, when he and sporting director Graeme Lowdon left the team.
Booth will join Toro Rosso with immediate effect and will take up his consultancy responsibilities for the team from this week's Russian Grand Prix.
"It is a great honour to join such a well-established and competitive team as Scuderia Toro Rosso,” said John Booth.
"It is a team that has achieved so much in a relatively short space of time.
“I am looking forward to getting started and working with Franz and the team this weekend in Sochi.”
Toro Rosso team boss Franz Tost added: "I have known John for many years and I am delighted to welcome him to the team.
“Formula 1 is becoming ever more complex, with recent changes on the tyre front, car set-up, radio communications and so forth.
“Therefore, having a competitive car and talented drivers, both of which we have, on its own is not enough.
“With his vast experience I am sure John will help the team raise its game and become a more effective force over a race weekend."
