Cinven boss swaps roles after 22 years at helm

* Cinven names Hugh Langmuir managing partner

* Robin Hall becomes executive chairman

LONDON, July 6 (Reuters) - Robin Hall, one of Europe's longest-standing private equity bosses, is swapping his role as managing partner of European buyout firm Cinven [CINV.UL], the firm said on Monday.

Hall, who has been managing partner of Cinven since 1988, will take up the newly created role of executive chairman, overseeing the day-to-day management of the firm and its 6.5 billion euro ($9.1 billion) fourth fund, which closed in mid-2006.

Hugh Langmuir succeeds him as managing partner and will gradually wind down his daily investment duties to lead the medium- and long-term strategic development of the business.

After 22 years at the helm of the private equity group, Hall said it was now the "natural time to bring in a fresh perspective on our future strategy".

"The timing fits with my longstanding wish to relinquish the managing partner role at the age of 60," said Hall, adding he would continue to manage the business through the investment cycle of the fund.

Most unlisted private equity funds have a 10-year closed cycle, with the first five years spent investing and the second five years selling portfolio companies. By mid-2011, Cinven should have completed the investment phase of its fund.
