The unravelling of the property empire of Simon Halabi has continued after his property advisory company was put into liquidation.

The demise of Buckingham Securities Holdings comes after the secretive Syrian-born entrepreneur had £1.15bn of debt called in on his portfolio of nine offices which includes the headquarters of Aviva, the insurer, and two London offices of JP Morgan.

MCR, the corporate restructuring specialists, have been appointed liquidators and called into Buckingham’s luxury Mayfair base.
