Exclusive: RBS asks restructuring chief to shrink investment bank
The changes will see Donald Workman hand over the responsibility for running RBS's investment bank to Cullinan, who already runs RBS's internal 'bad bank' and is overseeing the sale of RBS's U.S. business Citizens and its Williams & Glynn business in Britain, an enlarged role.
It is not clear what role Workman will take.
The bank, 79 percent-owned by the government, is under pressure from lawmakers to focus on lending to British households and businesses.
