This was my understanding - that it was Malaysian regulations that prevented this from happening. If it is, I can't find any such regulations, but I can find lots of examples of Malaysians investing 100s of millions in the U.K. Which makes me think this is more about FFP. I'm now wondering what the rules were in February 2016 (Prnarth's post points at 2016/17) when Tan publicly announced an immediate debt to conversion of £68m.
