Financial services group Prudential expects to save as much as £25m a year from creating a single global IT infrastructure to support all its brands, including online bank Egg.
Prudential chief executive Mark Tucker said the company would retain Egg, after previously putting the pioneering online operation up for sale.
Tucker said Prudential would also retain a federal structure for its various brands, but said greater integration at the operational level was needed, and that included IT.
He said work was already underway to create a single global IT infrastructure that should save the company between £20m and £25m per year.
The planned re-organisation includes a review of the company's datacentre operations, which are currently outsourced to Capgemini.
