Manor sporting director Graeme Lowdon has confirmed that Abu Dhabi will be his final race with the team, following his recent resignation.
As Motorsport.com reported at the Mexican Grand Prix, Lowdon and team principal John Booth have both decided to step down from the team they set up amid disagreements with its new owners about long-term plans.
Although he had previously declined to comment on the situation, Lowdon confirmed in Brazil on Friday that he was leaving after the season finale.
"Abu Dhabi's going to my last race with the team," he said. "The most important task this year was to make sure that the team continued racing.
"We had to stop before the end of last season, we weren't in Abu Dhabi last year, and that required an awful lot of hard work and an awful lot of commitment as well.
"It's quite well documented, the staff were all made redundant on the 7th of November, 2014 and things looked pretty bleak at that particular time.
"My own opinion is that Formula 1 racing teams are pretty precious things and something that deserves effort in making sure it continues. Certainly my belief in the team at that stage never wavered once.
"We worked very, very hard to make sure that the team was in a position to continue racing. And we had a lot of help."
He added: "From my point of view, this has been a pretty difficult season but that's secondary to the fact that the team continues, and that's the most important thing."
