US investment giant Brandes has once again trimmed its stake in Marks & Spencer, 6 1/2p better at 363 1/2p. The group has sold 3,278 American depositary receipts and 125,400 ordinary shares to cut its holding in the retailer to 12.41%. Brandes raised $18m (£10m) at the beginning of the month when it offloaded almost 500,000 ADRs, one of which is the equivalent of six ordinary shares.
