The former McLaren team principal Ron Dennis has returned as chief executive, charged with resurrecting the fortunes of the ailing Formula One giants.
Dennis, already the chairman of the McLaren Group, was in charge of the team from 1982 until 2009. During that time, he helped mastermind 10 world drivers titles and seven constructors crowns.
But last year, under new principal Martin Whitmarsh, McLaren endured their worst season for three decades, failing to score a podium finish for the first time since 1980.
Now Whitmarsh's future is in doubt, in what some see as an internal coup, the 66-year-old Dennis effectively regaining overall control of the former world champions.
The Briton will combine Whitmarsh's duties as Group CEO with his existing role of Group chairman and head of the McLaren Automotive sportscar division.
McLaren will have former world champion Jenson Button and Danish rookie Kevin Magnussen behind the wheel in the 2014 season.
Last season they finished fifth in the constructors' championship, with Button ninth in the drivers' standings, and Sergio Perez in 11th place.
