Last week it emerged they had purchased up to 21 properties in Dublin, most of them in south city areas, in the late 1990s and early 2000s, and are still the owners of the bulk of these apartments.
It has now emerged that the couple, who are aged 71 and 63 respectively, are also the owners of 13 apartments in the Isle of Dogs area of London.
It is believed the couple bought these apartments in the late 2000s. Efforts to contact them yesterday were not successful.
You tried twanging on the guy-ropes, did you?
