London - Former McLaren team boss Martin Whitmarsh is returning to Formula One in a temporary role advising the sport's governing body on cost control measures.

A spokesman for the International Automobile Federation said on Tuesday Whitmarsh had been invited to help them "in defining financial regulations for fair and sustainable competition".

Whitmarsh left former world champion McLaren, a team he had been with for 25 years, in 2014 when his predecessor Ron Dennis resumed control of its Formula One operations. Dennis has since also left McLaren and sold his shares.

After leaving Formula One, where he had also been chairman of the now-defunct Formula One Teams' Association, Whitmarsh became chief executive of Olympic yachtsman Ben Ainslie's America's Cup challenge in 2015. He was replaced in that role in November 2017, taking an advisory position instead.

Whitmarsh is also on the Global Advisory Board of electric series Formula E.
