Lord Blyth, the chairman and chief executive of Boots Diageo, is to join an investment banking boutique as its senior adviser for the UK market, reports the Financial Times.

The move will boost the profile of Greenhill & Company, the mergers and acquisitions advisory firm, whose clients have included FTSE 100 constituents such as 3i, Whitbread and Cable & Wireless. The appointment is likely to lead to other senior European business executives being offered roles with Greenhill. Lord Blyth, who will maintain an office at its London headquarters, will spend one or two days a week at the firm.
