A regional daily editor replaced his usual weekly column with a blank list to represent the lack of information made public about the murder of a private investigator.

The South Wales Argus has marked the 29th anniversary of the death of Daniel Morgan by labelling the failure to bring his killer to justice as a “national disgrace”, amid claims of a police cover-up.

Mr Morgan, originally from Llanfrechfa, near Cwmbran, was found in a South London car park after being attacked with an axe.

At an inquest in April 1988, a bookkeeper employed by Mr Morgan’s company Southern Investigations alleged his partner and a detective sergeant in the police had planned the contract murder.

However, no-one has ever been convicted over the crime despite numerous secret inquiries being held since.

A front page editorial marking the anniversary of Mr Morgan’s killing was published yesterday, along with the below column by editor Kevin Ward inside the paper.

It reads: “This week’s column lists in detail everything the powers-that-be have told the public in the 29 years since private detective Daniel Morgan was killed.”

The column is surrounded by blank space.

The Argus’s front page editorial, pictured below, reads: “Despite the case being the subject of several criminal investigations, nobody has yet been successfully prosecuted. In our view this is nothing short of a national disgrace.

“Mr Morgan’s death has also been at the epicentre of a storm of allegations of police corruption and cover-up. Yet Mr Morgan’s family who have led a dignified and long campaign to get the answers they deserve seem no closer to seeing the matter resolved.”

Three years ago Home Secretary Theresa May announced that the government was setting up the Daniel Morgan Independent Panel to review the police handling of the murder investigation, but there is little in the way of concrete information coming out about the panel’s findings.

Now Newport West MP Paul Flynn has asked for the Tiberius report on police corruption to be made public today on the anniversary of Mr Morgan’s death.

The Argus concludes: “The publication of the Tiberius report would be a fitting way to mark the anniversary and might go some way to answering at least some of the many questions surrounding this particular case.”
