A LEAKED REPORT from the Monopolies and Mergers Commission urges trade and industry secretary Margaret Beckett to ban recommended retail prices on electrical goods - on the grounds that they have led to price-fixing and collusion between retailers. As the news broke, shares in Dixons [which also owns Currys] fell ten points and Kingfisher [owner of Comet] dipped 6½ points. A table of price comparisons compiled by the Daily Telegraph shows remarkable price parity between the main electrical retail and department store chains, whereas discounters such as Buyers & Sellers and Hot & Cold Inc offer substantial savings on high street prices - over £200 on ovens, for example.
