Impeachment threat for Musharraf
Ruling coalition parties in Pakistan say they have agreed "in principle" to start impeachment proceedings against President Pervez Musharraf.
Their representatives are said to be looking at a draft impeachment resolution, after three days of talks.
The president's allies were defeated in elections in February, but he has so far resisted pressure to quit.
Correspondents say there are no other confirmed details about how an impeachment process might proceed.
They say the question of whether or not to impeach Mr Musharraf has threatened to divide the governing coalition.
The president has previously said he would prefer to resign than face impeachment.
Last year, he gave up control of the army, the country's most powerful institution, but he retains the power to dissolve parliament.
How the military reacts to any efforts to oust him would be crucial in determining his fate.
Mr Musharraf has delayed his departure to China, where he was due to attend the opening of the Olympic Games.
