That we, the taxpayer will pick up the tab for. He has no discernable income, just like the vast majority of his family.
Even if were served criminal charges, there's not a cat in hell's chance he'll ever go to the US. His mum and brother will never agree to send him, neither will his nephew probably either. A Tory government is more likely to give NHS workers a 200% pay rise than even consider forcing him over there.
He'll be tried in absentia, or agree to settle, and it will slowly fizzle out as a story once the money is quietly paid. Disgusting but likely.
