Saudi Arabia said today it had signed an agreement with the British government to buy 72 Eurofighter Typhoon jets from BAE Systems for £4.43 billion sterling ($8.84 billion).
"A contract was signed between the two governments to buy the plane on Tuesday, Shaaban 29 (September 11th) at a cost of £4,430 million pounds sterling," a statement on official news agency SPA said, attributed to a Defence Ministry official.
A deal including the jets as well as weapons and long-term maintenance of the aircraft is expected to raise its value to £20 billion, analysts say.
Saudi Arabia will pay the same price per jet as those sold to Britain, the statement said.
It cited a preliminary agreement in December 2005 in which Britain pledged to transfer technology and investment to the Saudi defence industry, as well as to train Saudi pilots.
It gave no more details.
A spokeswoman for the UK's Ministry of Defence declined to confirm the report, reiterating the ministry's position that negotiations were continuing and were expected to conclude by the end of the year.
The deal became the focus of a political storm last year when the British government halted a probe of BAE by the country's Serious Fraud Office (SFO) after Saudi Arabia warned it might cancel the order if the investigation went ahead.
The probe concerned allegations of corruption in a previous arms deal between Britain and Saudi Arabia involving BAE.
Past arms deals with Saudi Arabia are the biggest export pacts in UK history, worth an estimated £43 billion.
In June, the US Department of Justice also launched an investigation into BAE over its compliance with anti-bribery laws, including its past dealings with Saudi Arabia.
