Bumi Plc’s shares soared by more than 45% today after the Bakrie family proposed an audacious split with the London-listed, Indonesia-focused coal mining investment vehicle which they created with Rothschild before falling out last year. In another twist, the divorce plan has been drawn up by City banker Ian Hannam who was fined £450,000 for market abuse by the Financial Services Authority in April, although he is appealing his fine. He created the original Bumi Bakrie link-up when he was the lead resources dealmaker at JP Morgan Cazenove from whom he resigned following the fine.
