It is true that Bob Miller on 'Slaughter at the farm' said Jeremy came downstairs at the funeral reception, pointed at his 'Hugo Boss' suit and said 'Me Boss'.
It is also true BW said Jeremy put his feet on the WHF office desk & said 'I'm in charge now'. Whether that was before he had given himself a pay rise or not, I do not know.
So yes, if there was money involved, Jeremy may have tried to manage things from a distance. Although Neville had said he had no business sense. But there is no chance Jeremy would have got his boots muddy.
