Pakistan's ruling coalition parties say they will begin impeachment proceedings against President Pervez Musharraf.
Party leaders Asif Ali Zardari and Nawaz Sharif made the announcement after three days of talks.
They would need a two-thirds majority to impeach.
Mr Musharraf took power in a bloodless coup in 1999.
He gave up control of the army last year and his allies were defeated in February's Rebels blamed for Afghan attack ...

Mr Musharraf has previously said he would resign rather than face impeachment proceedings.
New territory
Mr Zardari, of the Pakistan People's Party (PPP), and the PML-N's Narwaz Sharif announced the impeachment move at a press conference in Islamabad.
Mr Zardari said: "We have good news for democracy. The coalition believes it is imperative to move for impeachment against General Musharraf."
Before any impeachment vote, Mr Musharraf must first face votes of confidence in the national and four provincial assemblies.
The two leaders also promised to restore judges sacked under Mr Musharraf's emergency rule once impeachment was successful.
The BBC's Mark Dummett in Islamabad says an impeachment would take Pakistani politics into new territory, since no Pakistani leader has faced it before.
The president is still thought to have heavy influence over the military and its reaction will remain crucial.
Pakistan has been ruled by military leaders for more than half of its existence since Partition in 1948.
