ISLAMABAD -  The government yesterday vowed to block protests in Islamabad if opposition leader Imran Khan pushes ahead with plans to shut down the government and transport in the capital from November 2.

The threatened protest has prompted worries of a repeat of a crippling occupation of Islamabad that Khan led in 2014 after he rejected Prime Minister Nawaz Sharif’s election win.

The chairman of Pakistan Tehreek-e-Insaf has demanded that Nawaz Sharif resign over the Panama Papers data leak that linked the premier’s family to offshore wealth. The PM and his family denies any wrongdoing.

The opposition leader has seized on the Panama Papers scandal as a fresh opportunity to try to unseat Sharif.

However, government spokesman Pervaiz Rashid said on Monday there would be no repeat of 2014, as Khan vowed the same day that a million people would protest.

“It is the government’s responsibility to ensure that life in the capital goes on as normal,” Rashid told a press conference in Islamabad. “The law will take its course against elements trying to shut down Islamabad.” The information minister was not explicit how the government would thwart the protests.

Leaked documents from the Panama-based Mossack Fonseca law firm appeared to show that PM Sharif’s daughter and two sons own offshore holding companies registered in the British Virgin Islands.  Holding offshore companies is not illegal in Pakistan, but Khan has implied the money was gained by corruption. Members of Nawaz Sharif’s cabinet addressed a press conference on Saturday and accused Khan himself of money laundering and tax evasion. His party did not respond to calls seeking comment.

The allegations follow Khan’s acknowledgement in May that he used an off-shore company to legally avoid paying British tax on a London property sale. The admission temporarily eased the pressure on Sharif’s government but the opposition is once again using the Panama Papers to try and unseat Sharif.
