The Pakistan People's Party has been in government for five years but it has been keeping a low profile during the current election campaign.
Its leader, President Asif Zardari, came to power in 2008 following the assassination of his wife, the former prime minister Benazir Bhutto.
With just a few more days until polling day, the President's sister Faryal Talpur, has been campaigning in Benazir Bhutto's former constituency of Larkana in Sindh.
