"Imran Khan today stated that it had come to his attention that some ministers in Khyber-Pakhtunkhwa are indulging in corruption," said a statement from the Pakistan Tehrik-e-Insaf party.
"Khan has demanded the Chief Minister immediately investigate and take action against these ministers."
The Tehrik-e-Insaf chief noted that his party was given a mandate for two main commitments - bringing peace to the country, especially Khyber-Pakhtunkhwa and stamping out corruption.
He said there could be absolutely no compromise on these issues.
