Last week, an Islamabad court sentenced Khan to three years in prison after finding him guilty of corrupt practices in the Toshakhana case. Khan was later arrested at his residence in Lahore.
"Imran Ahmad Khan Niazi is disqualified … for a period of five years, and de-notified as a returned candidate from the NA-45 Kurram-1 constituency," the commission said in a statement, citing a court’s decision on Khan’s imprisonment.
According to Pakistan's constitution, Khan is formally barred from holding any public office for five years following the court’s decision.
