@diablo It is possible. Just not easy nor cheap. You have to build a structure over it, with multiple foreign entities, involving partnerships, foundations, trusts etc
But if you want to keep your UK bank account it gets complicated to handle it.
regular UK banks will shut the door as soon as they see something like this these days, unless you open a suitcase with millions in cash in front of their manager. You can be sure that they'll find a solution then.
Criminals just don't care and simply enter fake info in the psc register. (2 years in jail if found)
I read there are only 6 employees at companies house registrations and they just check that forms are not empty, they don't and cannot do any KYC/AML checks.
So it's plenty of criminals still laundering money in UK as nothing happens...
Also plenty of companies starting and closing before the annual confirmation, so they don't disclose the PSC. What's going to stop you to rinse and repeat each year with a new company?
