While watching boxer Ricky Hatton's victorious title fight in Las Vegas, the former Take That singer stood to reveal an appeal T-shirt.

The bout was watched by millions of people around the world and photographers clamoured to get the shot.

Among the thousands of English fans in the crowd was Gene Bennett, from Manchester, who said: "It was a touching gesture.

"He must have known lots of TV cameras and photographers would be looking at him, so he used his fame for a good cause."

Meanwhile, in Malta, police say they have received 17 reported sightings of Madeleine, who was snatched from her family's holiday flatin Portugal on May 3.

A spokesman said: "We don't disregard any lead, but of those that have been put forward until now, none have allowed us to verify anything significant."

Officers insist they will continue to investigate any sightings.

However, they doubt the four-year-old was taken to the island.

They also question whether she would be shown in public by her abductors because of the intense media coverage of the case.
