A group of British lawmakers plan to invoke a parliamentary procedure last used more than one hundred-fifty years ago to impeach Prime Minister Tony Blair (news - web sites) over the war in Iraq (news - web sites), British newspapers said on Thursday.  

   Eleven members of parliament, mainly Welsh and Scottish nationalists who opposed the war and two opposition Conservatives, want to use the dated practice to force Blair to defend himself at Westminster over his decision to go to war.  

 Although it has almost no chance of success and is likely to be seen as little more than a publicity stunt, the plan will throw the spotlight back on the reasons Blair gave the country for going to war, the newspapers said.
