If an estate exceed the thresholds, UK Inheritance tax is paid by the estates of someone who is UK domiciled, even if they are not resident in the UK, when they die. Non Uk residents would only be subject to inheritance tax in the UK, if they had UK assets at their time of death.
-> reading between the figs, that's only if domiciled, having citizenship doesn't result in domiciled... (had me worried there for a moment).
Surely You buy citizenship from Turkey (or similar)︃ - you then obtain a name in Arabic, you then renounce British/other, you then use︄ that and apply for a third citizenship, and then do that in 'traditional English', and︅ renounce Turkish/other.
You've just name hopped three times 😉
