'Stop being mean' was the message to Manchester United, down 4p at 196p, from its own broker. ML says the payout should be 11p a share, not a stingy 4p. But the City had the knives out for Newcastle United, which slumped 2 1/2p to 30 1/2p as various rumours circulated. Turnover reached 300,000 shares in a market where dealers will normally quote a price in 2000 at a time. The club said rumours that manager Sir Bobby Robson was about to resign were untrue.
