Reports from Newsnight's Peter Marshall on allegations of corruption and inquiries into the British arms firm BAE's overseas deals.
A Serious Fraud Office inquiry into BAE's Al Yamamah deal with Saudi Arabia was stopped in December 2006 by the government, with attorney general Lord Goldsmith announcing that it was threatening the UK's national security.
Campaigning groups are currently trying to prove in court that hopes of winning a huge new arms contract from Saudi Arabia influenced officials. Newsnight's Peter Marshall has been investigating BAE for some time.

BUILT ON BRIBERY? - JUNE 2006
We've never sold so much of anything to anyone as we have sold arms to Saudi Arabia. It's Britain's most valued customer, our most lucrative trade - and also the most controversial.
