UK-backed move could help spread cost of developing fighter jet and drones, but may prove controversial

Saudi Arabia has asked the UK, Japan and Italy to be made a full partner in their joint effort to build the next generation of fighter jets, in a move backed by the British government.

Companies from the UK, Japan and Italy are working together to build a new fighter jet and other systems such as drones under the Global Combat Air Programme (GCAP), also known as Tempest. The programme aims to deliver the first planes by 2035, a tight turnaround.
