Colm Kelleher, this year named as one of Financial News's 100 most influential people in Europe's financial markets, has been named sole head of Morgan Stanley's institutional securities division.

Kelleher is co-president of institutional securities alongside Paul Taubman but is to assume outright responsibility for the unit when Taubman retires after 30 years with the Wall Street bank at the end of the year. Morgan Stanley confirmed the move in a statement today.
