Hetherington became majority owner by 6th May 2025 so well within the year under review. And there's no way he would ever take on £20m of debt at London. So there will no doubt be belt and braces legal documents in place to cover off responsibility (or lack of) relating to that liability.
It is puzzling that it still shows though, I'd love to know the details of that arrangement. If Hetherington/Lockyer can work some magic on Hughes personally and coax him back into taking an interest that would be a very good result.
