The defence, at the time of the trial, probably did not make any issues with regard to their knowledge of Julie Mugford's negotiations with the NOTW because their client was in the same boat so there was no moral or principled high ground to be gained.
Page 272, 'Blood Relations' - Outside, it was dark. At two minutes to six, the jury returned to court on the judge's orders. The jury foreman announced that they had reached no unanimous verdict on any of the five murder indictments. Neither was a majority verdict likely in the time available that evening. The judge decided to call it a day, and sent the jury to a hotel for the night. Downstairs in his cell, Jeremy Bamber was keeping an iron grip on his emotions. One observer found him 'discerningly composed'. He was discussing what he would do when released the following day. He was bandying figures for which he planned to sell his story to the newspapers - somewhat unattractive behaviour, in the opinion of one of his legal team. A group of them sat with Jeremy, trying to buoy up his spirits but feeling increasingly uncomfortable about his obsession with a newspaper deal. The best offer he'd had, he said, was £40,000. Couldn't they get him a better offer than that? After all, he was pointing out, if he was convicted, Julie had been promised £15,000 for her story. She was already ensconced at the Chelsea Holiday Inn in Sloane Street, closeted with two reporters from the News of the World.
Page 277 details - The deal that Julie Mugford had struck with the News of the World gave the newspaper exclusive rights to her story and pictures in return for £15,000, but the deal only stood if Bamber was convicted. (The same paper had secured exclusive rights to Jeremy Bamber's own story had he been found not guilty. That deal would have earned Bamber the sum of £40,000, a figure Bamber himself had complained was hardly adequate given the explosive nature of the revelations he was promising about his relations.)
Why does Jeremy not produce his contract with NOTW and say Julie had a similar contract which stood if there was a conviction? Julie's evidence must therefore be considered unreliable?
The reason, I suspect, is that such an argument when the same tests are applied to Jeremy's position would undermine his own evidence in court.
