Khurram Sher Zaman has warned the Sindh government against imposing a lockdown in Karachi, saying that the ruling PTI will stand against the provincial government if such a decision is made.

"You (PPP government) want to disturb the Centre by locking Karachi, you want to cause economic damage to the federal government by shutting down Karachi," he alleged.

He said that the federal government has given relief to millions of businesses by waiving off utility bills for a few months.
