There is no shortage of space in Friday's papers given over to the new inquiry by the Office of Fair Trading into the big four supermarkets.
The Guardian believes the OFT inquiry will give small shops the chance to fight back.
The Times warns against hysteria, as consumers have benefited greatly from lower prices and intense competition.

Rooney, who as the Telegraph points out already earns the gross national product of a small African country, has a questionable literary ability.
The Independent offers some advice on what titles not to choose.

The Independent is alone in reporting the newspaper tycoon Robert Maxwell was being investigated for war crimes shortly before he drowned 15 years ago.
It has seen a file released by the Met Police which shows that he was to be interviewed about the murder of an unarmed German civilian in 1945.

Official figures showed overpayments had more than tripled from £40 million in 2001 to £130m last year.
Charity Help the Aged described the move as heartless.
