Manor Marussia has confirmed that former McLaren man Dave Ryan has been appointed to the newly-created position of Racing Director.
Ryan spent 34 years with McLaren before his departure in 2009, after which he formed his own sportscar team to compete in the Blancpain Endurance Series.
Manor also publicly confirmed that John Booth and Graeme Lowdon will depart the outfit at the end of the season.
"I’m very excited to be joining the Manor at a pivotal time in their development," said Ryan.
"Having spent time with [Manor owner] Stephen [Fitzpatrick], and understood his vision for the future, it is clear he has ensured there is a strong platform from which the team can make big steps forward in the seasons ahead.
"Manor has all the hallmarks of a fiercely competitive racing team, but having grown up in a much more contemporary Formula 1 era, it is a very lean operation with a collaborative culture, which leaves it well placed to contend with the sport’s future direction.
"There is clearly a big challenge ahead and a lot of work to do, but I can’t wait to meet the wider team and get down to business."
