He said that the supermarket chain had seen "some dramatic changes in shopping" driven by the country being in recession, with people buying a smaller weekly shop than they used to and topping up later in the week.

That's a million more than was shopping with us a year ago and they are finding that we are helping them with the challenges of their weekly budget. And that is under a lot of pressure at the moment.
