Pakistan’s Supreme Court on Monday ordered Prime Minister Yousuf Raza Gilani to appear before judges to face contempt charges.
The court said that Gilani must answer questions on January 19 over the government’s failure to pursue corruption cases against the president and other senior officials.
President Asif Ali Zadari has faced a series of corruption allegations since the 1990s, including accusations of accepting bribes.
In 2009, the Supreme Court struck down an amnesty deal protecting him and his aides from prosecution. Zadari insists he still has immunity as head of state.
The 56-year-old widower of former PM Benazir Bhutto won the presidency in September 2008. His wife was assassinated on December 27 the previous year as she attended an election rally.
