Well, he won't have very big shoes to fill: Embattled oil giant BP is planning to replace their disgraced CEO Tony Hayward as soon as Monday, according to an anonymous U.S. official. The leading candidate to take on the role is Bob Dudley, who is currently the company's managing director. BP is tamping down public speculation, though, insisting as of Sunday that Hayward "remains BP's chief executive, and he has the confidence of the board and senior management." BP's board, which will meet on Monday, would have to approve Dudley as the new CEO before he could take the reins. Rumor has it that Hayward has been on his way out for some time, but the company wanted to be seen making some progress on plugging the leak before a management shakeup.
