Tesco sees half-year profits fall

The UK's biggest supermarket chain, Tesco, has reported its first fall in profits since 1994.

Pre-tax profit for the six months to 25 August came in at £1.7bn, down 11.6% from the same period last year.

The retailer is in the middle of a £1bn investment programme to improve its stores in the UK.

Chief executive Philip Clarke told the BBC the company are "making improvements that customers will notice".
