According to a close supporter, Pakistani Prime Minister Imran Khan is in risk of losing his coalition partners in a no-confidence vote demanded by the opposition, citing a “tilt” by his coalition partners towards their opponents.

The opposition is attempting to unseat the cricketer-turned-politician in a vote that might take place as soon as this month, following a no-confidence resolution introduced in parliament last week.

“He is in grave danger,” Pervaiz Elahi, the leader of one of Khan’s ruling coalition’s four parties, told television station HUM News late Tuesday.

In an interview, the senior politician continued, “They all have a tilt toward opposition.” He was referring to the four parties, which have a total of 20 seats in the lower house of parliament.

Khan’s party, which currently holds 155 seats in the lower chamber, would fall short of the 172 MPs required to retain power if they were not included.

Elahi would not leave the government, according to Khan’s ministers, while other coalition partners are contemplating their options. Elahi’s party’s spokesman did not immediately respond to a request for comment.

After gathering thousands of people in a campaign accusing Khan of mismanaging the economy, governance, and foreign policy, Pakistan’s opposition is seeking to oust him. There has never been a Pakistani prime minister who has completed his term.

The Pakistan Muslim League-Nawaz (PML-N) and the Pakistan People’s Party (PPP) of former prime ministers Nawaz Sharif and Benazir Bhutto make up the combined opposition, which has almost 163 seats in the lower house.

The no-confidence vote requires a simple majority of 172 votes to pass.

Elahi stated of the opposition, “They have the required number… even more than that.”

Elahi, the speaker of the Punjab legislature, has been negotiating with the opposition regarding the composition of the next government in the event of Khan’s demise.

According to the opposition and political observers, Khan has a rift with Pakistan’s powerful military, which they believe is necessary for any political party to succeed in the same way that the former cricketer’s upstart party did four years ago.

The allegations are denied by Khan and the military.

In the midst of the numbers game, both sides have called for protest sit-in demonstrations outside parliament in Islamabad, the capital, before of the vote, increasing the likelihood of riots and violence, according to commentators.
