Technical director Bob Bell is to leave Mercedes at the end of the Formula One season and will not be replaced.
Mercedes announced the Northern Irishman’s departure in a statement today, detailing plans to hand over Bell's duties to technical executive director Paddy Lowe.
Mercedes said: "Bob resigned his position in December 2013 and will leave the team at the end of November 2014, with the intention of pursuing new challenges outside the company.
"He has held the position of technical director since April 2011.
"Moving forward, the team will streamline its technical organisation and executive director (technical) Paddy Lowe will assume the responsibilities previously held by Bob.
"The role of technical director will not be replaced."
Bell, 56, first moved into motor racing when joining McLaren in 1982, and had subsequent spells at Benetton, Jordan and Renault before switching to Mercedes.
