The struggling Jordan Formula One team have parted company with sporting director Trevor Carlin.
The Jordan team have failed to pick up any points so far this season
Carlin took over at Jordan as part of the Midland Group buy-out, but he has endured an unhappy start to life in Formula One.
Carlin has quit with immediate effect to concentrate on his Carlin Motorsport Formula Three team, but will still act in an advisory capacity for the team.
He will be replaced by Adrian Burgess, who is promoted from sporting manager.
Carlin said: "I am very pleased to be involved in the whole Midland F1 project from its conception, and I hand over my role as sporting director at Jordan Grand Prix to Adrian Burgess, knowing he will do a superb job.
"Team owner Alex Shnaider and managing director Colin Kolles have a very clear vision of where they want to take Midland F1 and the purchase of the Jordan Grand Prix team was the first step."
