Yup, especially if he suspects that he's being chucked under the bus. This bloke is way out his depth, and Ashley is ruthless. Honestly I hope there's correspondence (Charnley's kept some sort of record) implicating Ashley, basically painting the narrative that Ashley is more hands-on than it's often reported, and this tax avoidance scheme was hatched from the very top. Early Christmas present if Charnley has covered his arse and he flips on his paymaster.
Ashley needs to take the rat on a trip on his fishing boat.
