Barclays PLC's (BCS) Roger Jenkins, the executive who was behind the raising of billions to boost the U.K. bank last year, Friday confirmed his departure as he leaves to set up a new corporate finance advisory firm.

Jenkins, executive chairman of investment banking and investment management for Barclays in the Middle East, told the U.K. bank last year he wanted to consider other opportunities, but agreed to stay on until the completion of a number of projects, including the sale of iShares, Barclays' exchange-traded funds unit, which was ultimately bought by U.S. asset manager BlackRock for $13 billion.

In his new firm, Jenkins will advise corporate finance clients and also plans to look for alternative investment opportunities. He will continue to work with Barclays Capital, in particular advising it on its business in the Middle East.

"I have had an amazing 25 years with Barclays, including 12 years with Barclays Capital, working with a dynamic leadership team which has turned Barclays Capital into the fastest growing investment bank of the decade. Now is a good time for a change," Jenkins said.
