Spencer has accused “Panorama” programme reporter, who conducted the interview, Martin Bashir of showing him fake documents to urge his sister to participate in the interview. 

In the bombshell interview, viewed by a record of 22.8 million people, Diana talked in detail about her collapsing marriage with Prince Charles. 

She said “there were three people” in her marriage, Charles, his long-time lover Camilla Parker-Bowles and she herself, and also revealed she had been unfaithful.

In 1996, Diana and Charles formally divorced and after a year the princess died in a car crash in Paris. 

New reports have claimed that Bashir used underhand methods to persuade the late princess for the interview.

“This is an important investigation which I will start straight away,” the former Supreme Court judge said in a statement, as quoted by news agency AFP. 

“I will ensure it is both thorough and fair.”
