ISLAMABAD: Pakistan’s Supreme Court ordered the arrest of the prime minister Tuesday on corruption allegations, ratcheting up pressure on a government that is also facing street protests led by a preacher who has a history of ties to the army.

The combination of the arrest order and the mass protest in the capital Islamabad led by Muslim preacher Mohammad Tahirul Qadri raised fears among politicians that the military was working with the judiciary to force out a civilian leader.

“There is no doubt that Qadri’s march and the Supreme Court’s verdict were masterminded by the military establishment of Pakistan,” Fawad Chaudhry, an aide to Prime Minister Raja Pervez Ashraf, told Reuters.

“The military can intervene at this moment as the Supreme Court has opened a way for it.”

However, the ruling coalition led by the Pakistan Peoples’ Party has a majority in parliament and lawmakers can simply elect another prime minister if Ashraf is ousted. In June, Ashraf replaced Prime Minister Yusuf Raza Gilani, who was disqualified by the court in a previous showdown between the government and the judiciary.

Also, elections are due in a few months and President Asif Ali Zardari hopes to lead the first civilian government in Pakistan’s 65 years as an independent nation that will complete its full term.

But power struggles will distract the unpopular government from tackling an array of problems – a Taliban insurgency, economic stagnation and growing sectarian tensions triggered by bomb attacks and tit-for-tat shootings.

The military, which sees itself as the guarantor of Pakistan’s stability, has long regarded the PPP-led government as corrupt, incompetent and unable to prevent the nuclear-armed country from falling apart.

Pakistan’s powerful army has a long history of coups and intervening in politics. But these days generals seem to have little appetite for a coup. Army chief General Ashfaq Kayani has vowed to keep the military out of politics.

But many believe top military leaders still try to exert behind-the-scenes influence, and any moves by the military in the latest crisis could not happen without a green light from Kayani, arguably the most powerful man in Pakistan.

The protest by Qadri and his followers has also been seen by commentators as being orchestrated by the military to add to the pressure on Zardari’s government, although the military has denied any ties to the preacher.

Thousands of followers of the populist preacher camped near the federal parliament cheered and waved Pakistani flags as television channels broadcast news of the Supreme Court’s order to arrest Ashraf on charges of corruption.

“We don’t want any of those old politicians. They just take all the people’s money,” said 19-year-old student Mohammad Wasim. “We congratulate the whole nation [on the Supreme Court’s order]. Now we have to take the rest of the thieves to court.”

Government officials said they were baffled by the arrest order, which came hours after Chief Justice Iftikhar Chaudhry said elections should go ahead as scheduled.

“This was totally unexpected,” an official in Ashraf’s office said. “The prime minister and two or three of his friends were watching Qadri speak on television and this suddenly happened.”

Qadri, who played a role in backing a military coup in 1999, threatened to remain camped out near the federal parliament, with thousands of supporters defiant after police fired tear gas and the government ignored his ultimatum to disband parliament.

The fiery orator returned home from Canada less than a month ago to lead a call for electoral reforms to bar corrupt politicians from office that has made him an instant hit among Pakistanis disillusioned with the state.

In a speech from behind a bullet-proof shield in front of parliament, he praised the military and the judiciary, the country’s two other power centers.

“[The government] has wasted and brought a bad end to our armed forces, those armed forces who are highly sincere, highly competent and highly capable and highly professional,” he said, alternating between Urdu and English.

“Even they can’t do anything because the political government isn’t able to deliver anything from this land. Judgments are being passed by our great, independent judiciary but the government is not ready to implement them.”

Qadri is demanding that the government dissolve the legislature and announce the formation of a caretaker government to oversee the run-up to elections.
