What might well be helpful is this being brought to the attention of someone like Martin Lewis or Watchdog or similar (or all) and bring pressure to bear. I’m sure a story like ‘disability funding drawn off to make huge profits’ would peak their interest.
Whlst I fully agreee it might/will be a good idea to involve those you mention, the flip side of that is the Daily Mail will no doubt want to stick their two-penneth in.
