David Davis, the former Conservative shadow home secretary, said how a row between the CIA and FBI could have prevented them from uncovering the 9/11 terrorist plot, the Daily Telegraph reported.
He said that American authorities had "sealed" a case in a US court relating to a dispute between two British businessmen and an Afghan billionaire Ehsan Bayat over the setting up of a mobile phone network in Afghanistan in the late 1990s.
According to reports, US intelligence agencies had privately backed the venture, hoping to be able to monitor calls made over the new network. Mr Bayat was an FBI informer, Mr Davis said.
"We cannot say for certain that if US intelligence agencies had tapped the Afghan phone network sooner, we would have intercepted evidence in time to stop the 9/11 attacks. But it seems likely," Mr Davis said. "It looks like a huge opportunity was missed."
