Britain’s largest supermarket chain Tesco saw its shares’ value plummet yesterday after four of its senior managers were suspended as suspicion around the massaging of profit figures emerged.

The over-statement has been estimated at a staggering £250 million. 

The group’s chief executive Dave Lewis, who had been informed of the fudged accounts last Friday through a whistleblower,  said he expected the company to “operate with integrity and transparency.”
