Khan became the first premier in the country’s history to be voted out of power through a no-confidence motion held early Sunday and vacated the Prime Minister’s official residence minutes before he lost the crucial no-trust vote in the National Assembly.

“The Islamabad High Court (IHC) will hear on Monday an application requesting for placing the names of the former prime minister Imran Khan and ex-ministers on the Exit Control List (ECL),” The News newspaper reported on Sunday.

The ECL is a system of border control maintained by the Government of Pakistan under the Exit from Pakistan (Control) Ordinance, 1981. The people on the list are prohibited from leaving the country.

The court will also order an investigation into an alleged threat letter, the report said.

Filed by Maulvi Iqbal Haider, the plea seeks a probe into the alleged threat letter and an inquiry against Khan and the ministers.

It has also requested the IHC to put Deputy Speaker of the National Assembly Qasim Suri and Pakistan’s Ambassador to the United States Asad Majeed on the ECL along with Khan’s Foreign Minister Shah Mahmood Qureshi and Information Minister Fawad Chaudhry, the report said.

The joint Opposition’s no-confidence motion, which required 172 votes in the 342-strong parliament to pass, was supported by 174 lawmakers on Sunday, ending Khan’s prime ministerial term and seemingly bringing an end to the protracted political crisis in Pakistan.
