Steph Duckworth takes up this new appointment after serving successfully in two senior management positions in London. First as Chief Operating Officer EMEA following Collins Stewart Tullett's acquisition of Prebon Yamane and the subsequent integration of the two business; secondly, and more recently, as Chief Executive Officer EMEA during the reorganisation of the Collins Stewart Tullett group which saw Tullett Prebon, by then the world's second largest inter dealer broker, become a publicly listed company.

Steph will move to New York and will work along side Lou Scotto, Chief Executive Officer the Americas.

Henry Ann becomes Chief Executive Officer EMEA, after several senior appointments across Tullett Prebon and its predecessor companies. Most recently Henry has been global head of the company's data sales division, Tullett Prebon Information.

Based in London, Henry will report to Terry Smith the group Chief Executive Officer, and will join the company's Executive Committee. He will retain responsibility for Tullett Prebon Information until it is transferred to the group's Electronic Broking division in 2008.

Terry Smith, Chief Executive Officer of Tullett Prebon plc, said: 'Steph and Henry have solid experience behind them, and importantly have held management positions in international roles. It is our intention to continue growing Tullett Prebon and we will therefore employ our key staff where they can most contribute to the success of the company."

Both appointments are effective from 1 February 2008.
