Red Bull Racing's head of aerodynamics Ben Agathangelou has left the team following a reshuffle of the aerodynamics department, led by chief technical officer Adrian Newey.
The Milton Keynes-based team made the most of the four-week break in the Grand Prix calendar to evaluate their start of the season, and part of those efforts included Newey making changes to their staffing structure.
Newey had planned to move Agathangelou into a more organisational role, to make way for Peter Prodromou to take the role of head of aerodynamics. But Agathangelou was unhappy with his new offered position, and he and the team subsequently agreed to part ways.
Team principal Christian Horner told autosport.com: "Adrian took the decision that he wanted to restructure the aero department - just to tidy up the structure.
"Part of the plan was to make Peter Prodromou head of aerodynamics, and that meant we had to reappraise Ben's role.
"We offered him a different position that he didn't feel comfortable with, so we came to an amicable solution. But he is still contracted to the company."
Horner added that the team would not look to recruit a replacement for Agathangelou from outside the company.
It is understood that Agathangelou will now be on gardening leave for up to 12 months, until his contract with the team runs out.
