Protesters demand the setup of a criminal court for former British Premier Tony Blair as he gets a grilling from the Iraq War inquiry in London. Hundreds of protesters and anti-war activists have held a rally in London, calling for the trial of Blair for sending British troops to Iraq. The angry demonstrators chanted, "Tony Blair, war criminal," reportedly forcing him to enter the venue through a side entrance. The protesters say they are convinced the former premier gave them the slip. "The real question Tony Blair needs to answer in the end will be at The Hague and before a war crimes tribunal," Reuters quoted Chairman of Stop the War Coalition Andrew Murray as saying on Friday. The Iraq War panel is also expected to determine the legitimacy of the war. Blair defended his decision to send 45,000 British troops to Iraq in 2003 and wage war in the country. He also referred to routine meetings with former US President George W. Bush and his own government officials without specifying details of the proceedings in his meetings. Blair's questioning is to continue in order to establish the motives behind the Iraq invasion.
