Princess Diana documentary relives the worst of the royal family

It was promoted as the princess at her "most candid, natural and charismatic".

There was plenty of emotional music, news clips, quotes from close friends and of course the tapes she'd recorded with her voice coach.

It was also brutally raw in parts.

And as it was being aired The Sun newspaper was reporting more salacious details that it says came from a BBC cameraman.

The Sun reports: "Princess Diana claimed she once spied on Prince Charles on the toilet having 'phone sex talk' with his now wife Camilla Parker Bowles."

Some of the youngest members of the royal family played important roles on the day — three-year-old Prince George and two-year-old Princess Charlotte arrived with their mother Catherine and acted as a page boy and a flower girl respectively.

Ms Middleton arrived in a open-top car accompanied by her father, waving to crowds gathered near St Mark's church in Englefield, about 80 kilometres west of London.

Prince William walked up to the church with his younger brother Prince Harry.
