British authorities have opened a new front in the widening investigation into allegations of bribery at Halliburton, the American oil services business, while it was being run by the US vice-president, Dick Cheney.
The Guardian has learned that the Serious Fraud Office has joined the international effort at the request of the US Department of Justice in Washington. French and Nigerian officials are already involved in the inquiry.
Halliburton has become a political liability for the Bush administration as the US prepares to vote in presidential elections next week.
The company, one of the chief government contractors in Iraq and Afghanistan, has been dogged by controversy, which includes claims of White House favouritism in awarding the firm billions of dollars of contracts without being forced to bid and Pentagon allegations that the firm has massively overcharged for its work.
It emerged late on Thursday that the FBI had launched an inquiry into how Halliburton secured contracts in Iraq, so far worth almost $9bn (£4.9bn).
