Rolls-Royce is set to axe more than 4,000 jobs this week as the aero-engine maker tries to slash costs and boost profits.

Chief executive Warren East is expected to announce the cull of middle managers and back-office staff at an analyst briefing on Friday, dealing a devastating blow to its Derby base, says The Sunday Times.

Mr East says Rolls-Royce, which also has a big manufacturing facility at Inchinnan near Glasgow, suffers from unnecessary costs, duplicated roles and too many layers of management.

City analysts believe that up to 10% of its 50,000-strong workforce could be axed.
