During my time as president we have fought many battles, not least almost annually the one to retain the British Grand Prix.

From the five years, 1968-73, if you were an F1 driver at that time, there was a very likely chance that you would have died.

It takes leadership to improve safety. And I started off the movement in my time, but the person who has done more over the past 20 to 30 years and who has led it is Professor Sid Watkins.

We were racing at circuits where there were no crash barriers in front of the pits, and fuel was lying about in churns in the pit lane. A car could easily crash into the pits at any time. It was ridiculous.

In one year I travelled 450,000 miles by air.

I would have been a much more popular Wolrd Champion if I had always said what people wanted to hear. I might have been dead, but definitely more popular.
