ISLAMABAD: Following serious allegations of rigging in the 2013 general elections, the leader of the opposition in the National Assembly on Tuesday endorsed Pakistan Tehreek-i-Insaf (PTI) chief Imran Khan's call for the resignation of all members of the Election Commission.

In an informal conversation with reporters at the Parliament House, opposition leader Khurshid Shah said that members should immediately step down after the accusations of rigging by the PTI.

Shah said that he still did not doubt the intentions of Fakhruddin G Ebrahim, but he claimed that the former Chief Election Commissioner failed to conduct the election in a transparent manner.

The senior Pakistan People's Party (PPP) leader said that the government still had time to bring about reforms in the electoral system, which he said would take almost three years to be implemented.

Shah said that a joint session of the PTI, Jamaat-i-Islami (JI) and PPP has been called for Wednesday.

Opposition parties will meet tomorrow to work together on proposals for electoral reforms and forward them to the government, he said.

He claimed that the entire nation was demanding electoral reforms and not just the PTI.
