Nielsen ponders potential bid for Tesco's Dunhummby unit

Information and research company Nielsen is thought to be considering a potential offer for Dunnhumby, Tesco's clubcard scheme business.

The research giant is understood to have demonstrated an interest in the loyalty scheme operator, but no offer has been made, the Sunday Times reported.

Ahead of next month's bidding round, there has been strong interest in the company, which processes data relating to one billion shoppers around the world.

The publication cited industry sources who suggest the selling price could be well in excess of the expected £2bn figure.
