The caretaker government that conducted the May 11 polls had refused to initiate proceedings against Musharraf under Article 6 of the Constitution for treason because of its limited mandate, but the PML-N has decided not to spare the former army chief who had overthrown the government of Nawaz Sharif in 1999.
"Yes we have decided to try Musharraf for treason in the Supreme Court. Musharraf had violated the Constitution and he should face the music," PML-N parliamentarian Tariq Azeem said.
"Sharif has made it clear that he has no personal issue with Musharraf but he should be tried for breaking the law and violating the Constitution," Azeem said.
The caretaker government recently informed the Supreme court of its inability to conduct the trial of Musharraf.
