Apparently Sheikha Mozah bint Nasser, mother of the Emir of Qatar, during the reign of her late husband, bought two adjacent houses for £120m from the Crown Estate in London's Cornwall Terrace. As with the revelations about the King of Jordan's property purchases in the same investigation, there is no suggestion that the Sheikha did anything illegal, but the properties were bought through offshore companies and avoided paying an estimated £18.5m Stamp Duty Land Tax.

My perception, which might certainly be wrong, is that the revelations will be less damaging to the Qatari ruling family given the nature of their autocratic emirate than to the King of Jordan, whose kingdom, while still a dictatorship, at least has some degree of popular participation and a more restless population.
