"This is a really significant deal, because it's pound8 billion ($10.7 billion) worth of orders... these are jobs that will last for 10 years, making the (Eurofighter) Typhoons, so really big for our country," he said after holding talks with Turkish President Recep Tayyip Erodogan in Ankara.

Britain's defence ministry said the order would involve 20 Eurofighters in what it described as the "biggest fighter jet deal in a generation".

It said the agreement would strengthen Turkey's combat capabilities and bolster "NATO's strength in a key region".

"This is the southeast flank of NATO, and so having that capability locked in with the United Kingdom is really important for NATO as well," Starmer said in Ankara.
