SYDNEY, (AFP) - Prime Minister John Howard is facing renewed attacks over his support for the US-led war in Iraq as new evidence emerged that a top weapons expert had warned him there was nothing to justify invasion.
The Sydney Morning Herald said Bob Mathews, described as Australia's leading expert on weapons of mass destruction, told Howard three days before his announcement that Australia was committing troops to the invasion, that the case for war was based on falsehoods.
Mathews, a 35-year veteran of the government's Defence Science and Technology Organisation, also warned Howard in a letter that support for the war would make Australia a bigger terrorist target.
The paper said it had obtained a copy of Mathews' letter to Howard and had been appraised of what one colleague had reportedly described as "disgraceful" treatment of Mathews before and after he sent the letter.
"There are no reasons at the present time to justify supporting a US-led invasion of Iraq," the letter quoted Mathews as telling Howard.
The letter also urged Howard to make a last-ditch effort to persuade the Americans to abandon their war plans.
The report described Mathews' action as a last, desperate act after his superiors repeatedly blocked him from expressing his views.
Mathews wrote to Howard as a private citizen three days before he committed the nation to sending some 2,000 defence personnel to the conflict.
The report, latest of a series alleging Howard was well warned against joining the war in Iraq, comes at a bad time for the government, now in the throes of a bitterly fought campaign for the October 9 election.
Howard's enthusiastic support for US President George W. Bush's "coalition of the willing" in Iraq and the Labor opposition's pledge to pull Australian troops out by Christmas have been a major election issue.
In his televised address to the nation advising of his decision to take Australia into the war, Howard said the reason "above all others" for joining the war was the threat posed by terrorists with weapons of mass destruction.
The opposition moved quickly Saturday to capitalise on the report saying it was further clear evidence Howard had ignored expert advice not to take Australia into the conflict.
"Bob Mathews was right in saying that there were big question marks over the weapons of mass destruction, Mr Howard ignored that advice in the letter and decided to go in search of weapons of mass destruction that didn't exist," Labor leader Mark Latham said in Melbourne.
"Mr Howard said it would make us safer, it hasn't, he's had it wrong, this is an incompetent government on national security and the letter today and the information today further confirms that point of view."
Opinion polls are showing conflicting results, with one poll Saturday giving Howard a substantial lead and another earlier this week putting Labor ahead.
