You’re dropping lots of ‘hints’ here
@Empire but providing absolutely nothing other than, seemingly, ‘gut instinct’ to support it.
I think most of us suspect that part of the deal for getting Castore onboard and rid of the Fat C*nt involved SDI getting some sort of deal to buy kit from Castore. Provided Rangers still get their slice and that deal is between Castore /SDI I can live with that, albeit we’d love to see him with nothing.
You, though, appear to be suggesting more. Anything to support that? Nothing on Companies House suggests any Fat C*nt/SDI involvement at corporate level with Castore.
