'First of all, on behalf of the team and all at Mercedes, I wish to send our deepest condolences to Birgit, Niki's children, his family and close friends.
'Niki will always remain one of the greatest legends of our sport - he combined heroism, humanity and honesty inside and outside the cockpit.
'His passing leaves a void in Formula One. We haven't just lost a hero who staged the most remarkable comeback ever seen, but also a man who brought precious clarity and candour to modern Formula One. He will be greatly missed as our voice of common sense.
