"Figures released by the Land Registry reveal that more than £100 billion of property in central London alone is held in offshore companies and therefore avoids certain taxes.

The Sunday Times analysed an inventory of 18,700 title deeds, obtained through a Freedom of Information Act request, and found that millions of pounds could be lost through a loophole."
