Islamabad - Pakistan's governing coalition was set Monday to initiate impeachment proceedings against President Pervez Musharraf after he defied calls overnight to resign in the face of "an unarguable trial."
The National Assembly, or lower house of parliament, convened at 5 pm (1100 GMT). It is expected see a tirade of accusations against the retired army general, but a formal battle will start only once a charge sheet is tabled later in the week.
