@Hulahoop7: It would directly reduce Eurofighter GmbH's order book and Eurofighters are not built in each country in their totality, the Saudi ones will be built in the UK, Germany, Spain and Italy, final assembly for the first 24 will be in the UK however.
The contract by the way apparently forbids resales or counting exports as a partner country's purchase, I can't see the UK reducing it's order at all.
