Always fear a wounded beast, as you never know when it will bite back.

That happened yesterday as the monster of Britain’s high streets, Tesco , returned with a bang.

The supermarket giant announced sales in the UK grew last year for the first time since 2009.

Globally, just under £50billion – £1,582 per second – poured into its tills . The company said it had slashed debts, repaired battered relations with suppliers and service was improving.

It is all a long way from the dark times just a few years ago.

Former chief executive Sir Terry Leahy had turned Tesco from a thriving UK chain into a worldwide colossus.

At its peak, the retailer had stores all throughout Europe and Asia and accounted for nearly 32p of every £1 spent in UK grocers. Then it hit the skids.
