1233 GMT - Diageo's plan to cut costs and boost top-line growth should please investors, Citi analysts write in a note. The London-listed producer of Smirnoff vodka and Guinness stout set out a plan to drive revenue and shore up its operating profit through a $1 billion cost-cutting program. "This is likely to be well-received," Citi says. Shares gain 6.5% to 1,748 pence, putting the stock among the FTSE 100's biggest risers Thursday. (joshua.kirby@wsj.com; @joshualeokirby))
