Manor F1 bossed John Booth and Graeme Lowdon have tendered their resignations and will leave the British team at the end of the 2015 season.
Founder and team principal Booth and president Lowdon are said to have a difference of opinion with the minnows' new owner Stephen Fitzpatrick about the progression of the team.
Ovo Energy boss Fitzpatrick, who rescued the team from bankruptcy last winter, is believed to be funding the team out of his own pocket with an estimated £30 million of his fortune already poured into the team. Fitzpatrick and business partner Abdulla Boulsien have apparently been increasingly distancing themselves from Booth and Lowdon, promoting the pair to leave the team.
Although Booth, Lowdon and Manor have yet to comment ont he situation, the pair will remain in charge of the team for the rest of the season before seeking pastures new, possibly in the FIA World Endurance Championship.
Unless a dramatic U-turn takes place, Booth and Lowdon will leave the team they have been a part of together since the team entered Formula One (under the Virgin Racing banner) in 2010. More team members could follow them through the exit door.
