Marsh has been hit by news of a string of further senior departures this week, as the company unveiled a major global restructure.

It has emerged that the head of UK placement Chris Tabbitt has left the broking giant with the last few weeks.

Marsh was also dealt a blow with the depatures of US chief operating officer Mark Feuer and Marsh America’s chief executive Phil Moyles.

Meanwhile, Dan Glaser Marsh’s global chief executive, unveiled a major restructure this week, which will see the broker consolidated into a US/Canada division and an international division.

Alexander Moczarski, currently chief executive of the Europe, Middle East and Africa region, will head the international division. The US/Canada division will be led by ex-chairman of Willis risk solutions Joseph McSweeny.

Glaser said the changes would “reduce complexity and improve efficiencies within the organisation”.

Last year, Glaser dismissed suggestions that he had his work cut out in his new position.

He said: “I don’t see it that way. Marsh is a world class brokerage firm with a strong nucleus of talented people. If you are the right executive, you don’t feel pressure.”

Marsh & McLennan chief executive Michael Cherkasky – who had previously lambasted Marsh for poor results in 2007 – was axed last month.
