UK drinks conglomerate Diageo is reported to be seeking bids in excess of US$2.3bn for the Burger King fastfood division it is planning to divest. The sale is the last part of Diageo's campaign to focus exclusively on its drinks portfolio, which includes Guinness beer, Smirnoff vodka and Johnnie Walker whisky. The group sold its Pillsbury food division last year for US$10.5bn.
