Addressing the foundation stone-laying ceremony for revamping of Nankana Sahib Railway Station here on Sunday, he said that Pakistan Tehreek-e-Insaf (PTI) Chairman Imran Khan and Pakistan People's Party (PPP) Chairman Bilawal Bhutto Zardari should focus on public welfare projects in their respective provinces instead of indulging in protest politics.
He said that Imran should pay attention to the problems of Khyber-Pakhtunkhwa and the PPP should provide basic amenities to the downtrodden people of Sindh.
"Prime Minister Muhammad Nawaz Sharif's name is not mentioned in the Panama Papers, but Imran Khan himself owns an offshore company," he added.
Khawaja Saad said that Imran Khan should not punish the people for his own failures.
Earlier, the minister while performing the foundation stone-laying ceremony, said that the project would be completed in 18 months at a cost of about Rs 160 million.
The minister warned the opposition that the government was all prepared to tackle negative tactics of the opposition.
"We will welcome the constructive politics of the opposition, but it is unfortunate that their every step appears to be damaging democracy," the minister added.
