Toro Rosso has named former Manor F1 boss John Booth as its director of racing ahead of this weekend's Russian Grand Prix.
The appointment sees the experienced Englishman return to the F1 paddock after resigning from his team principal role at the struggling Manor squad at the end of last season.
Since leaving the sport, Booth along with former Manor F1 sporting director Graeme Lowdon have set up a new Manor sportscars outfit, which competes in the FIA World Endurance Championship.
Booth is expected to dovetail his FIA WEC commitments alongside this new consultancy role at Toro Rosso.
“It is a great honour to join such a well-established and competitive team as Scuderia Toro Rosso” said 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 boss Franz Tost believes Booth's wealth of experience will be beneficial to the Red Bull junior squad.
“I have known John for many years and I am delighted to welcome him to the team,” said Tost.
“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.”
