I doubt it - more than a million people turned out to line the route of Diana's funeral procession. Almost 33 million watched on TV in the UK, and an estimated 2 billion people worldwide.
I watched the ceremony on TV and then drove a few miles to watch the car with her coffin go up onto the M1 - there were tens of thousands of people on both sides of the road, many of them throwing flowers in front of and onto the car. I've never seen anything like it. One of my neighbours followed the police rolling road block for ten miles along the motorway.
