Everyone remembers where they were when they heard about Diana. Her death was one of those ultra-rare news stories - the JFK, 9/11 category.

This month marks the 20th anniversary of the Paris car crash that ended her life; killed aged 36 in extraordinarily ordinary circumstances by a speeding drunk driver.

The emotional incontinence that swept Britain following her death is now almost a little embarrassing.

It is probably the sea of floral tributes left by members of the public that have remained burned into the collective memory; what is less well-remembered is the ugly, mob-like atmosphere that quickly infected the crowds that gathered in London from the date of her death to her funeral.
