Former cricketer Imran Khan has been sworn-in as the new prime minister of Pakistan, more than two decades after he entered politics.
He was elected prime minister in a vote at the country's National Assembly on Friday.
His PTI party won the most seats in July's elections and Mr Khan has become PM with the help of small parties.
Correspondents say his priority will be to address a financial crisis, with the economy in need of a huge bailout.
In Friday's vote, Khan was backed by 176 members. His opponent, Pakistan Muslim League-Nawaz (PML-N) president Shahbaz Sharif, received 96 votes.
In a speech to parliament, 65-year-old Mr Khan reiterated his campaign promise to hold "corrupt" politicians to account, and to improve opportunities for young people.
"First of all, we will start strict accountability. I promise to my God that everyone who looted this country will be made accountable," he said.
"I did not climb on any dictator's shoulders; I reached this place after struggling for 22 years."
Opposition parties have claimed elements of last month's elections were rigged. Despite this, they agreed to take their seats in the assembly.
In the lead-up to the election, Khan was widely seen as the favoured candidate of the powerful military, which was accused of meddling to turn opinion against his rivals.
Exports such as textiles have taken a hit from cheaper products made by regional competitors, including China. Analysts say the new government may need to turn to the International Monetary Fund (IMF) for the country's second bailout since 2013, which could complicate efforts to boost welfare.
