Tesco on landbanking: "It is difficult to think of a more expensive and unrewarding competitive strategy than to sit on a landbank and do nothing."

Asda on competition: "65% of the urban population in Great Britain has fewer than four one-stop shop fascias and hence restricted choice, according to the Competition Commission's previous approach to assessing one-stop shop competition. Yet the planning regime potentially prevents entry in 72% of urban areas in GB with restricted choice."

Morrisons on planning: "Once planning permission is granted for grocery retailing it should be mandatory that the store is developed within a (very short) specified time period. Otherwise the land and associated permission must be divested to others willing to develop the store."

Sainsbury's on suppliers: "We believe suppliers would be well served by the expansion of the supplier code of practice to all competitors operating in the one-stop market."

Waitrose on its rivals: "Waitrose competes mainly with the other national supermarkets: Tesco, Sainsbury, Morrisons, Asda and Somerfield. Although Waitrose also faces competition from smaller stores (eg Aldi, Lidl, Netto, Iceland and Marks & Spencer), this is on a significantly lesser basis because their offerings fall well short of a full one-stop shopping grocery range."

M&S on commitment: "M&S has not stopped doing business with any core suppliers in the last five years."
