Qatari royal loses £150m in bank collapse

His Highness Sheikh Mohammed Bin Khalifa Al-Thani spent $282 million at the end of last month taking a 5% shareholding in Kaupthing, the banking group that went into administration earlier this week.

The acquisition of the stake in the bank — best-known in London for owning Singer & Friedlander — was seen at the time as a shot in the arm for Iceland's banks, which were coming under pressure to prove their solvency.
