Comrades in arms...

Bernie Ecclestone was back in the paddock at Interlagos, a home race of sorts for Formula 1's former supremo who now has more time to spend at his Brazilian ranch near Sao Paulo.

Bernie and Niki Lauda goe back a long way, and while the pair may have had their differences in the past, when one was the other's boss, a strong friendship has prevailed over the years.
