Dennis returns as chief exec

Ron Dennis has returned to the role of Group Chief Executive Officer of the McLaren Group and says he has been tasked with "improving our on-track and off-track performance".

The 66-year-old also held the role between 1982 and 2012 before becoming Chairman of the Group in 2013. Dennis was also McLaren's long-standing Team Principal before Martin Whitmarsh took over in 2009.

Whitmarsh had also held the role of CEO prior to Thursday's announcement but McLaren's statement made no reference to him or his future as Team Principal.

Dennis will combine the CEO role with his position as Chairman and says he will carry out a thorough review of the company's businesses to help McLaren "win at whatever we do".

"My fellow shareholders have mandated me to write an exciting new chapter in the story of McLaren, beginning by improving our on-track and off-track performance," Dennis said.

"Over the coming weeks I intend to undertake a thorough and objective review of each of our businesses with the intention of optimising every aspect of our existing operations, whilst identifying new areas of growth that capitalise on our technologies, and where appropriate further investing in them.

"During February, I will articulate a new Group strategy and implement the organisational structure best suited to achieving it. I am excited by the prospect of returning to the role of Group Chief Executive Officer and working with my many colleagues and fellow shareholders to fulfil our objective - which is to win at whatever we do."

McLaren endured one of the worst seasons in their history last year, when they failed to win a race for the first time since 2006 and also missed out on the podium for the first time in since 1980.

Their latest car, the MP4-29, will be launched on Friday January 24.
