Serious Fraud Office starts Tesco criminal investigation

The Serious Fraud Office (SFO) is carrying out a criminal investigation into accounting irregularities at supermarket giant Tesco.

Tesco says it has been "co-operating fully" with the SFO.

Last week, the supermarket announced that its profits had been overstated by £263m, up from an initial estimate, made last month, of £250m.

The inflated profit figure was the result of Tesco bringing forward rebates from suppliers.

Simon Gompertz reports.
