Pakistan’s embattled Prime Minister Imran Khan said Sunday he will seek early elections after sidestepping a no-confidence challenge and alleging that a conspiracy to topple his government had failed. The deputy speaker of Pakistan's Parliament threw out the opposition parties' no-confidence resolution and abruptly ended the session. Minutes later, Khan went on national television to say he will ask Pakistan's president to dissolve Parliament and call early elections. The developments came after Information Minister Fawad Chaudhry accused the opposition of colluding with a “foreign power” to stage a “regime change.” “I ask people to prepare for the next elections. Thank God, a conspiracy to topple the government has failed,” Khan said in his address. The opposition, which said it would stage a protest sit-in in Parliament, called the deputy speaker's ruling throwing out the no-confidence vote illegal and vowed to go to Pakistan's Supreme Court. The opposition arrived in Parliament ready to vote Khan out of power. They needed a simple majority of 172 votes in Pakistan's 342-seat Parliament to unseat Khan, a cricket star turned conservative Islamic politician. Khan's small but key coalition partners along with 17 of his own party members joined the opposition to oust him. The no-confidence vote had been expected some time after Parliament convened Sunday but parliamentary rules allow for three to seven days of debate. The opposition had said it has the numbers for an immediate vote. Giant metal containers blocked roads and entrances to the capital's diplomatic enclave and to Parliament and other sensitive government installations in the capital. A defiant Khan called for supporters to stage demonstrations countrywide to protest the vote. Khan has accused the opposition of being in cahoots with the United States to unseat him, saying America wants him gone over his foreign policy choices that often favor China and Russia. Khan has also been a strident opponent of America’s war on terror and Pakistan’s partnership in that war with Washington. Khan has circulated a memo which he insists provides proof that Washington conspired with Pakistan's opposition to unseat him because America wants “me, personally, gone ... and everything would be forgiven.” READ: Pakistan's PM faces tough challenge with no-confidence vote A loss for Khan would have given his opponents the opportunity to form a new government and rule until elections, which had been scheduled to be held next year. Residents of Pakistan’s largest province Punjab were set to vote Sunday for a new chief minister. Khan's choice faced a tough challenge and his opponents claimed they had enough votes to install their choice. With 60% of Pakistan's 220 million people living in Punjab, it is considered the most powerful of the country's four provinces. Also on Sunday the government announced the dismissal of the provincial governor, whose role is largely ceremonial and is chosen by the federal government. But it further deepened the political turmoil in Pakistan. Pakistan's main opposition parties, whose ideologies span the spectrum from left to right to radically religious, have been rallying for Khan's ouster almost since he was elected in 2018. Khan's win was mired in controversy amid widespread accusations that Pakistan's powerful army helped his Pakistan Tehreek Insaf (Justice) Party to victory. Asfandyar Mir, a senior expert with the Washington-based U.S. Institute of Peace, said the military's involvement in the 2018 polls undermined Khan's legitimacy from the outset. “The movement against Imran Khan’s government is inseparable from his controversial rise to power in the 2018 election, which was manipulated by the army to push Khan over the line,” said Mir. “That really undermined the legitimacy of the electoral exercise and created the grounds for the current turmoil. ” Pakistan's military has directly ruled Pakistan for more than half of its 75-year history, overthrowing successive democratically elected governments. For the remainder of that time it has indirectly manipulated elected governments from the sidelines. The opposition has also accused Khan of economic mismanagement, blaming him for rising prices and high inflation. Still, Khan's government is credited with maintaining a foreign reserve account of $18 billion and bringing in a record $29 billion last year from overseas Pakistanis. Khan's anti-corruption reputation is credited with encouraging expatriate Pakistanis to send money home. His government has also received international praise for its handling of the COVID-19 crisis and implementing so-called “smart lockdowns” rather than countrywide shutdowns. As a result, several of Pakistan's key industries, such as construction, have survived. Khan's leadership style has often been criticized as confrontational. “Khan’s biggest failing has been his insistence on remaining a partisan leader to the bitter end,” said Michael Kugelman, deputy director of the Asia Program at the Washington-based Wilson Center.

As a result, he’s burned too many bridges at a moment when he badly needs all the help he can get.” Khan’s insistence there is U.S. involvement in attempts to oust him exploits a deep-seated mistrust among many in Pakistan of U.S. intentions, particularly following 9/11, said Mir. Washington has often berated Pakistan for doing too little to fight Islamic militants even as thousands of Pakistanis have died in militant attacks and the army has lost more than 5,000 soldiers. Pakistan has been attacked for aiding Taliban insurgents while also being asked to bring them to the peace table. “The fact that it has such easy traction in Pakistan speaks to some of the damage U.S. foreign policy has done in the post 9/11 era in general and in Pakistan in particular,” said Mir. “There is a reservoir of anti-American sentiment in the country, which can be instrumentalized easily by politicians like Khan.”
