Honda's Arai leaves McLaren project

Honda has confirmed the departure of Yasuhisa Arai as Formula 1 boss.

It had been rumoured that the Japanese could lose his job following the disastrous start in 2015 to the new McLaren-Honda works collaboration.

"Yusuke Hasegawa has been assigned to replace Yasuhisa Arai to oversee the development, manufacturing and management of the F1 project," Honda confirmed.

Arai had been due to retire at the end of the season.
