JPMorgan has agreed to buy all the MF Global's shares in the London Metal Exchange, according to KPMG, administrators for MF Global's U.K. unit.  The company is paying £25 million for 600,000 Group A shares, which give JPMorgan voting rights in the company. In addition, the bank is buying 25,000 Group B shares with no voting rights for £2 million. The £25 million deal values the London Metal Exchange at £530 million to £560 million, although JPMorgan bought the position at a discount, according to a person with knowledge of the deal. With the deal, JPMorgan, which already owns 6.2 percent of the company, would be the largest shareholder of the exchange, with a 10.9 percent stake.  The purchase puts JPMorgan in prime position to benefit from any future sale of the large metal marketplace. Goldman Sachs, which holds a 9.5 percent, is the London Metal Exchange’s second-largest shareholder. Meanwhile, the administrator for the MF Global U.K.  business continues to progress on the sale of several aspects of that office.  For more info, go to [Dealbook, 11/23/11]
