Tufan Erginbilgiç says decision is for the government but German participation remains a possibility

The boss of Rolls-Royce has said he would welcome Germany helping to build Britain’s next-generation fighter jet, arguing that it would bring in more business for the project.

The aircraft, designed to replace the Eurofighter Typhoon, is a joint effort between the UK, Italy and Japan. Rolls-Royce is building the engine for the jet, which has attracted fresh attention as plans for a rival Franco-German warplane edge towards collapse.
