A blaze has caused multi-million pound damage at Tesco's biggest UK store in Sandhurst, Berkshire.
About 100 members of staff fled the 24-hour superstore after the fire broke out in the warehouse and ripped through the shop floor.
Fire investigators have been at the store all day searching for the cause of the fire. Neither arson or an accident have been ruled, according to a Berkshire fire spokesman.
As yet no loss adjuster has been appointed, he said.
