In a major blow to beleaguered Pakistan Prime Minister Yousuf Raza Gilani, the Supreme Court Friday rejected his appeal, asking him to appear before it on February 13 to frame of contempt charges for not reopening graft cases against President Asif Ali Zardari.

"Our appeal was rejected. As a result of this, Prime Minister Yousuf Raza Gilani will be charged for contempt of court on February 13. Inshallah, the Prime Minister will appear (in court) on February 13," Gilani's lawyer Aitzaz Ahsan told reporters outside the court.
