Bamber, who was found guilty of killing his adoptive parents, sister and nephews near Tolleshunt D'Arcy, Essex, in August 1985, has always maintained his innocence and has labelled ITV's six-part series White House Farm "a disgrace".

Speaking to this newspaper from Wakefield prison, Bamber also aimed criticism at author Carol Ann Lee's book - The Murders at White House Farm - on which the television drama is partly based.

Both Ms Lee and ITV highlighted the "meticulous research" which went into the book and subsequent series.

They also wrote to producers of the show and invited them to postpone screening the series until matters were resolved in the High Court.

Bamber maintains that his sister, Sheila 'Bambi' Caffell, killed parents Nevill and June and her twin six-year-old boys Nicholas and Daniel before turning the gun on herself in a murder/suicide.

Asked how he felt about the current series, Bamber said: "The ITV drama is a disgrace.

"It is being broadcast in the middle of a judicial review and is likely to interfere with the CPS being able to pursue the option of a retrial.

"It is promoted as 'a drama' as Carol Ann Lee's book that it's based upon is, for the most part, simply made up."

"Everything in the book is meticulously footnoted, there is a very small piece of speculation at the end when I discuss how the murders could have been carried out but I make it very clear that that is the case.

"It {the series] is actually very fair to him. It's the story of his conviction and not the story of how he killed his family.
