Brit ish banking giant Barclays is to cut over 2,000 jobs in its retail and commercial businesses, it said Wednesday, a day after announcing a similar number of job losses in its investment divisions. The new cuts, which could affect staff in its high street branches, bring to over 4,000 the number of Barclays job losses as the banking sector struggles to recover from the credit crunch. A spokesman said the bank was consulting with the Unite labour union over the job losses. "Barclays continually reviews its operations and resources so that they function efficiently as business needs and customer requirements evolve. In the current market conditions, this is particularly important," he said.
