Barclays Capital has hired one of the top London-based equity bankers from UBS to lead the expansion of its UK equity underwriting and corporate broking business, as the bank continues to build its European investment banking division following the acquisition of Lehman Brothers' North American operations last year.

Jim Renwick, vice-chairman of UBS' global capital markets division, resigned from the Swiss bank in the past few days and is expected to join Barclays Capital in London as head of UK equity capital markets and corporate broking in September after a period of gardening leave, according to a source with knowledge of his move.
