New Lloyds Banking chief executive António Horta-Osório has stamped his authority with a shake-up of the retail bank and insurance divisions and the departure of two senior directors.Archie Kane, Group Executive Director for Insurance and Scotland, and Helen Weir, Group Executive Director for Retail, will both stand down after the next AGM. Lloyds said the duo would "receive no compensation beyond their contractual entitlements on leaving the group."Mrs Weir decided to stand down after a restructuring of the Retail banking division that will see Retail Products and Marketing taken on by Antonio Lorenzo, Group Director for the Wealth and International division. He will report directly to Mr Horta-Osório.Following Mr Kane's retirement the Insurance division will be managed in two separate divisions - Life, Pensions and Investments and General Insurance - and will now both report directly to Mr Horta-Osório."These changes to the group's management team will enable us to focus on meeting our 2011 targets, whilst putting in place some of the foundations which will enable us to deliver on our longer-term plans following the conclusion of the Strategic Review which is currently underway," Mr Horta-Osório said.
