Banks and one of Britain’s biggest food suppliers are poised to pursue Jamie Oliver over debts after the chef’s empire of restaurants collapsed.

The Daily Telegraph understands Oliver provided personal guarantees to lending giant HSBC and distributor Brakes after a previous restructuring, allowing them to claim against him personally for any unpaid bills.

Administrators were called in as Oliver’s portfolio of restaurants failed, costing a thousand jobs and leaving HSBC tens of millions of pounds out of pocket.

A further 300 jobs are at risk.
