Candidates backed by former Pakistani premier Imran Khan's party plan to form a government, a senior aide to the jailed politician says, calling on supporters to peacefully protest if final election results are not released.
The nuclear-armed South Asian nation voted on Thursday in a general election as the country struggles to recover from an economic crisis and battles militant violence in a deeply polarised political environment.
Both Khan and three-time former prime minister Nawaz Sharif declared victory on Friday.
Gohar Khan, the chairman of Khan's Pakistan Tehreek-Insaf (PTI) party who also acts as the former premier's lawyer, called on "all institutions" in Pakistan to respect his party's mandate.
At a media conference, he said if complete results of the polls were not released by Saturday night, the party would hold peaceful protests on Sunday outside government offices returning election results around the country.
Pakistan's army chief had congratulated the country on Saturday for the "successful conduct" of its national elections, saying the nation needed "stable hands" to move on from the politics of "anarchy and polarisation".
Pakistan Chief of Army Staff Asim Munir "wishes that these elections bring in political and economic stability and prove to be the harbinger of peace and prosperity", according to a statement released by the media wing of the military.
The United States, Britain and the European Union on Friday each expressed concerns about the electoral process, urging a probe into reported irregularities.
Pakistan's foreign office countered the international criticisms on Saturday, saying they ignored the "undeniable fact" of Pakistan conducting elections successfully.
"It is our hope that the process will be concluded effectively and it will reflect the will of the people," said former Nigerian president Goodluck Jonathan, who is leading the Commonwealth team to observe Pakistan's elections.
Sharif said his party had emerged as the largest and would talk to other groups to form a coalition government.
Khan, who is in jail, released an audio-visual message created with artificial intelligence rather than having a statement read out by his lawyers, as is usually the case.
Khan rejected Sharif's claim to victory in the message on social media platform X, calling on his supporters to celebrate what he called a win achieved despite a crackdown on his party.
Independent candidates backed by Khan won the largest share in parliament, despite his imprisonment for convictions on charges ranging from leaking state secrets to corruption to an unlawful marriage, and even though his party was barred from the polls.
About 100 of the winning candidates are independents, all but eight of them backed by Khan's party, said the Free and Fair Election Network, a non-profit electoral watchdog.
Khan's close aide and media advisor Zulfi Bukhari told Reuters the party would soon announce the banner it would ask independents to join.
In Pakistan, independent candidates cannot form a government on their own and need to join a party.
The banner for independent candidates backed by Khan's Pakistan Tehreek-e-Insaf (PTI) party will be announced within the next 24 hours, Bukhari said.
"And we have no fear of independents going anywhere because these are the people who have struggled for the last 18 months and endured all kinds of torture and oppression," he told Reuters in a voice note over WhatsApp.
Sharif's Pakistan Muslim League-Nawaz (PML-N) won 71 seats, while the Pakistan People's Party of Bilawal Bhutto Zardari, the son of assassinated premier Benazir Bhutto, got 53.
The rest were won by small parties and other independents, with more than a dozen seats still up for grabs more than 40 hours after polling ended.
