Members of perpetrator's family have complained that they believe he was beaten in custody.

The journalist who threw his shoes at former US President George W. Bush will face trial on February 19 for assaulting a visiting head of state, with a maximum 15-year prison term, a court official said.

Muntazer al-Zaidi's defence lawyers lost an appeal to have the charges against him reduced to a lesser offence of insulting Bush, rather than assaulting him.

"The Iraqi appeals court has rejected the appeal submitted by Muntader al-Zaidi's defence lawyer to change the charges, and decided to set February 19 as the date for trial," said Iraqi judiciary council spokesman Abdul-Sattar al-Birqdar.

Mr al-Zaidi has been held in jail in Baghdad since hurling both shoes Mr Bush at a December 14 news conference during the then-President's final visit to Iraq. Mr Bush ducked the flying shoes while the journalist called him a "dog". The act, captured on television, made Mr al-Zaidi a hero in much of the Arab world. In one tribute, an artist built a giant statue of a shoe, which was eventually dismantled, in ousted dictator Saddam Hussein's hometown Tikrit.

Iraqi law has a statute forbidding aggression against visiting leaders. Mr al-Zaidi's lawyers have argued that throwing a shoe could not be considered aggression because it could not cause actual harm, and was therefore only an insult.

Members of Mr al-Zaidi's family have complained that they believe he was beaten in custody. He was last seen in public being pummelled and wrestled out of the press conference in stocking feet.
