RB's diaries suggest this was pre planned.
Jeremy persuading Neville to leave the money in the safe, rather than taking it back to WHF. RB then saying immediately after the break in 'you know who that was don't you'.
It would not be rocket science for Neville to work out it was Jeremy. Barabara Wilson said Neville knew it was Jeremy, but did not prosecute. Which Jeremy probably suspected would happen.
Poor Neville couldn't even get the money back from Jeremy. As Jeremy quickly spent it, on slap up meals.
Perhaps Neville added it to the £2,000 RB said Jeremy already owed Neville. But Jeremy had told Neville he couldn't pay him back. Oh dear.
Five months later, Jeremy executed another pre planned crime. Or did he ?
