The Pakistan Muslim League-Nawaz (PMLN) and the Pakistan Peoples Party (PPP) reached an official agreement to form a new government shortly after the country witnessed tense controversial elections.

Candidates affiliated with former Prime Minister Imran Khan's Pakistan Tehreek-e-Insaf party (PTI) won more seats than the two parties in the controversial elections, which saw allegations of election rigging.

The popular leader has been sentenced to long years of jail and was barred from practicing politics after being charged with a series of alleged crimes. This forced PTI's party candidates to run as independents.

Despite the crackdown against the PTI, candidates supported by the party claimed the largest parliamentary bloc of 93 seats, but fell short of securing the 169-seat majority.

Pakistan witnessed a revelation on Saturday after senior bureaucrat Liaqat Ali Chattha confessed that he helped rig the country's elections. The commissioner of the city of Rawalpindi, where the headquarters of Pakistan's military is located, announced that he would surrender himself to the police.

Chattha, before resigning from his position, said he supervised the rigging of votes and "converted the losers into winners, reversing margins of 70,000 votes in 13 national assembly seats," he relayed to reporters, adding: "For committing such a heinous crime, I will hand myself over to the police".

His statement implicated the country's top judge and the head of the election commission, who rejected the claims but said they would "hold an inquiry".

The Human Rights Commission of Pakistan, a leading advocacy group, said the announcement of the "involvement of the state bureaucracy in rigging in Pakistan is beginning to be exposed" and brings corruption to light.
