Sainsbury's shareholder reveals stake

The Qatari investment group involved in a raid on Sainsbury's shares has said it holds a stake of 17.4% in the British supermarket chain.

The move by Delta Two will increase pressure on Sainsbury's as the fund is thought to have links with tycoon Robert Tchenguiz, who has a 5% holding in the retailer and is pressing for it to unlock the value of its property assets.
