Jaguar Land Rover CEO Adrian Mardell is stepping down after 35 years at the automaker, including the last three as CEO. Mardell's tenure brought increased profits to JLR, and he started a major restructuring of the automaker's brands and model lineups that's still underway.

Jaguar Land Rover chief Adrian Mardell will step down after more than three decades at the company, having said he wanted to retire after three years as CEO, a spokesperson for the automaker said on Thursday.

Adrian Mardell had worked with Ratan Tata after Tata Motors Ltd. bought Jaguar Land Rover Plc for $2.3 billion from Ford Motor Co. Since then, JLR has been part of the Tata Group.
