Profit-takers moved in on constructor Alfred McAlpine, down 4p to 292p despite revival of bid talk. Word is Gerald Ronson's Heron International wants to make an offer. McAlpine received a bid approach, three years ago, also thought to have been from Heron. It then attracted the interest of rival Bryant that led to it selling its housebuilding division to George Wimpey, off 13p to 325p, for £463m.
