I stand corrected...We'll never know of course...
"Hundreds of entries on the register do not reveal the beneficial owners of many overseas companies because they are owned by secretive trusts based offshore. The ultimate owners of these have been registered and are available to HMRC but not the general public"
Luckily there are still some investigative journalists out there...
"Conservative donors who have collectively given the party more than £21m since 2001 have been declared as the ultimate owners of UK properties held through more than 150 offshore companies in a new government register."

Nothing will change though
