BRITISH engine maker Rolls-Royce has seen annual profits soar 49 per cent thanks to strong engine orders and after-sales demand.

Pre-tax profits jumped to £584m, beating the £557m figure predicted by analysts.

Sales rose nine per cent to £6.6bn.

Rolls-Royce ranks third in the number of commercial jet engines it has in operation, behind General Electric and Pratt and Whitney.

It also sells military aircraft engines, ship engines and equipment used in the energy industry. Pictured are engineers working on a Trent 1000 engine, which Boeing has bought to power its latest plane, the 7E7 Dreamliner.
