The party was founded by Zulfikar Ali Bhutto on an “Islamic socialist” programme, won the 1970 election and won the 1977 election, only to be deposed by a military coup led by army chief General Zia ul-Haq.
Zulfikar Ali Bhutto was executed in 1979 after being found guilty of murdering an opponent.
His daughter Benazir Bhutto took over the party’s leadership, winning power again in 1988, and turning economic policy to the right and losing power to Nawaz Sharif’s Islamic Democratic Alliance in 1991.
The PPP won elections again in 1993 but the government, accused of corruption and ordering extra-judicial killings, was dismissed by President Farooq Leghari, a party member.
Benazir Bhutto left the country to be joined by Asif Ali Zardari after he had served a jail sentence in Pakistan.
She returned to Pakistan in 2007 in a deal with military ruler Pervez Musharraf but was assassinated.
Official leadership of the party passed to the couple’s son, Bilawal, a student at Oxford University in the UK.
The PPP was the largest party in parliament after the 2008 election and formed a coalition government, which has served out its mandate but faces problems being reelected.
Although it draws most of its votes from poorer sections of Pakistani society, the PPP is dominated by wealthy landowners, including the Bhutto family, and is strongest in Sindh province.
