The penalty for the offenses Andrew has committed is possibly life in prison.
The e-mails nailed Andrew's being complicit in and carrying through illegal actions. Like I said, Andrew was for sale, "if you give me the money, perks or both, I'll do whatever you want", plus I'm sure he threw in his royal status as his perk.
There was a former UK trade envoy featured on a podcast I was listening in on. He said he was livid when Andrew was name as trade envoy. He talked to the government about his concerns, namely Andrew's lack of any experience and....he could be manipulated. No one listened. Of course, Andrew's being chosen was pushed by the Monarch, also.
