ALAN Kebbell (Letters, June 19) criticised Channel Four for showing the documenentary about the car crash that killed Diana, Princess of Wales.

I, and many others in the UK and the world, are interested to find out if it was an accident or murder. Was she assassinated?

Were Prince Philip or Prince Charles involved? Let the public have the answers. She was the most thought of working member of the Royal family.

I did not think the documentary was insulting. People did not have to watch it, therefore what is their problem? Let us know all details as soon as possible.
