Niki Lauda has stood down from the board of directors at Air Berlin in order to concentrate on his new role with the Mercedes F1 team.

Lauda took up a management role with the Mercedes F1 team at the end of last year, with his appointment confirmed in the wake of the announcement that the squad had successfully poached Lewis Hamilton from McLaren.

Initially it was thought that the 63-year-old would work alongside Mercedes team principal, Ross Brawn and Mercedes motorsport boss, Norbert Haug. However Haug stood down at the end of 2012 by 'mutual agreement'. Haug later said the team's poor performance was the reason for his exit, rather than the arrival of Lauda.

Lauda, who won the F1 drivers' title in 1975, 1977 and 1984, previously held a management role with the now defunct Jaguar F1 team. He was also a consultant for Ferrari between 1992 to 1997.
