Pakistan's parliament will select a new prime minister on Monday (Apr 11), after Imran Khan was ousted in a no-confidence vote in the early hours of Sunday (Apr 10).
Shahbaz Sharif – the leader of an opposition coalition who worked to depose Mr Khan – is widely expected to win a majority of the vote.
Parliamentary voting will take place around 14:00 local time (09:00GMT).
Mr Khan, 69, was voted out after days of political drama and Supreme Court intervention.
He attempted to block a previous attempt to bring a no-confidence motion against him by dissolving parliament and calling for a snap election.
However, the country's Supreme Court upheld an opposition petition that his actions were unconstitutional and ordered the vote to go ahead.
