In December 2006, Saudi Arabia pressured Britain into halting a fraud investigation into the £43bn Al-Yamamah arms deal with Saudi Arabia.[17] Then, in September 2007, Saudi Arabia agreed a deal to buy 72 Eurofighter Typhoon combat jets from Britain. A British High Court later ruled that the British government had acted unlawfully in dropping the corruption inquiry, but this was overturned by the British House of Lords in July 2008 because Saudi Arabia had threatened to withdraw cooperation with Britain on security matters.[18]
