In an exclusive interview with The Times, the bodyguard claimed that, far from fleeing Baghdad, the three men held out in the capital for at least a week after its fall.

He said that they evaded repeated American attempts to assassinate or capture them, and even appeared in public under the noses of US troops.

During a three-hour interview in a house in a town an hour northwest of Baghdad, the bodyguard said that Saddam and his sons had remained in the capital throughout the war, convinced they could hold the city.

When the first bombs fell on a house in a southern suburb, where the Americans believed Saddam and his sons were meeting, he and Uday were on the other side of the city in one of dozens of safe houses belonging to trusted friends and relatives through which the three men were to pass in the weeks to come.

The bodyguard said the Americans’ next “decapitation” strike came a lot closer, and that Saddam survived only because several safe houses had come under attack and he suspected there was an informant within his camp.

Saddam asked the suspect, a captain, to prepare a safe house behind a restaurant in the Mansour district for a meeting. They arrived, and left again, almost immediately, by the back door. “Ten minutes after they went out of the door, it was bombed,” the bodyguard said.

Saddam had the captain summarily executed while the Pentagon was claiming that the strike had probably finished off Saddam and Uday.

The 28-year-old man, who asked for his real name to be kept secret for fear of reprisals, served as one of Uday’s coterie of handpicked personal bodyguards from 1997 until the moment his former boss finally left Baghdad to organise guerrilla resistance further north.

Uday bade him farewell with a $1,000 golden handshake, promising to be in touch again “when he was needed”. On Tuesday US troops killed Saddam’s son in a gunfight in the northern city of Mosul. Yesterday the Pentagon released pictures of his mutilated head.

When Baghdad fell on April 9, the three men were in separate houses in Adhamiya, a Sunni neighbourhood full of loyalists where Saddam had been on a televised walkabout two days before.

Uday’s bodyguard was not present on that occasion, but was there two days later when, to the astonishment of all around, Saddam and his sons appeared at Friday prayers at a mosque in Adhamiya, a few miles from where American troops were patrolling.

“There were crowds all around and an old woman came up to Saddam and asked, ‘What have you done to us?’,” the bodyguard recalled.
