The prime minister has branded comments made by Labour MP George Galloway on the war with Iraq "disgraceful and wrong".
Mr Blair expressed anger at the attack
Tony Blair said Mr Galloway would have to answer to Labour's National Executive over his outburst against the PM and US President George Bush.
In an interview for Abu Dhabi TV, the Glasgow Kelvin MP had accused Mr Blair and Mr Bush of lying to the armed forces about the likely length of the war.
He had also questioned the legality of the war and urged British soldiers to refuse to obey "illegal orders."
Referring to the two leaders, Mr Galloway said: "They have lied to the British Air Force and Navy when they said the battle of Iraq would be very quick and easy.
"They attacked Iraq like wolves. They attacked civilians."
Mr Blair said: "His comments were disgraceful and wrong.
"The Labour Party has got its own rules for dealing with that. The National Executive will deal with it.
"I am not going to set him up as a martyr to me. Let the party look at it on behalf of ordinary Labour Party members. People were very angry."
Responding to reports that he might face expulsion for the remarks, Mr Galloway said he would resist any attempt to oust him.
Also in The Sun interview, Mr Blair said he was prepared to quit if he had lost a crucial Commons vote on Iraq.
