My understanding is that the UK has been selling non-domiciled residency permits together with the tax freedom that goes with that for around £35,000. Hyper rich people have made use of this service and put their wealth through the UK banking system - no money laundering issues there. Meanwhile, when a parent gives his/her child £2000 a humiliating process demanding identification, proof of relationship, justification, affidavit, etc., etc. may ensue. To paraphrase the common refrain: Only in the UK.
