London: Britain's Serious Fraud Office (SFO) won the right on Thursday to appeal against a High Court ruling that criticised the halting of a corruption probe into a Saudi arms deal.

In the April 10 ruling, two judges had said the SFO had given in to Saudi threats over arms deals with Europe's biggest defence company, BAE Systems Plc.

On Thursday, Lord Justice Alan Moses and Justice Jeremy Sullivan formally quashed the decision of the SFO to drop an investigation.

At the same time they gave the SFO permission to appeal to Britain's highest court against their ruling. The appeal is now expected to be heard towards the end of this year.

Two anti-arms trade campaigners had said there was "very large scale bribery" over the state-to-state Al Yamamah deal and said the probe was halted after the threats.
