Jim Spence just sent this to me on twitter:

"He made an offer to ST in Feb 2017 before the foundation was thought of. It’s his money, the foundation isn’t involved. One other businessman was to come in with him. The money is sitting in an account still, only needing ST signature I’m told. But only on terms previously agreed"

He then got angry when I asked further questions saying it's got nothing to do with anyone. Even though he made it public by tweeting it earlier.
