Just saw it myself whilst setting up my recordings of 'Lorraine' and 'Loose Women'. A sad loss. Was so used to seeing him in the Merc garage. No visible signs of any ailments. 70 is still young, but I guess his body has been through more trauma than any of us could ever imagine. RIP.
Agree with all the sentiment here...RIP to a legend. This is a great read...some interesting facts I never knew (not that I'm any kind of F1 officianado) https://www.bbc.co.uk/sport/formula1/46781936
