As the senior leader of the region, he will be responsible for MF Global's European growth strategy including oversight of its London, Paris, Amsterdam and Geneva offices.

Rowsell previously served as the company's global head of equities since 2003 based in London.

'James has demonstrated an ability to translate strategy into real results,' says Bernard W. Dan, chief executive officer, MF Global. 'Over the past six years, he raised MF Global's equities business from a small regional start-up into a substantial international business with a comprehensive product and service offering. His considerable experience, strong relationships and proven leadership will play an important part in expanding MF Global's presence in Europe while driving existing and seizing new market opportunities in the region.'

Rowsell has more than 20 years of experience in the financial services industry. Prior to joining MF Global, he spent several years at Citigroup, most recently as head of equity sales for Europe.

Laurence O'Connell, who had been serving as the senior leader of Europe on an interim basis, has resumed his role as managing director of MF Global's Asia-Pacific operations.
