Boeing and the UK government have signed a deal which will see the aircraft manufacturer create 2,000 jobs an increase investment in the country.
Unveiling the details at the start of the Farnborough Airshow on Monday, Prime Minister David Cameron said the UK will purchase new Boeing P8 maritime patrol aircraft and Boeing will increase its spending on research & development efforts in the UK.
Announcing the deal, Mr Cameron said: "Whatever uncertainties our country faces, I want the message to go out loud and clear: the UK will continue to lead the world in both civil and defence aerospace."
As part of the deal, Boeing will also invest around £100 million in Scotland's RAF Lossiemouth, creating 100 jobs.

Meanwhile, the UK government announced a further £365m for R&D in the aerospace industry, which will be jointly funded by private firms operating in the industry. In a statement, the government said: "These are part of the work of the Aerospace Growth Partnership, which will publish a new strategy at Farnborough setting out plans to maintain the UK aerospace sector's leading position.
"This includes a new supply chain competitiveness charter signed by 11 major companies across the aerospace sector."
