PM Yousuf Raza Gilani on Saturday said the country cannot afford holding of mid-term election, and stressed the need for joint efforts from all political parties to overcome national challenges. While talking to journalists after visiting Ministry of Population here, PM Gilani declined the impression that Leader of the Opposition had demanded for mid-term election. Gilani said JI leader Qazi Hussain Ahmad by participating in the by-election in Buner, had proved that there was a complete democracy in the country.
