Ex-PM Imran Khan has raised the demand for the sacking of US Assistant Secretary of State for Central and South Asia Donald Lu for "sheer arrogance and bad manners".

"Imagine telling the ambassador of a country of 220 million people that you get rid of your prime minister," he said in an interview on the CNN programme Connect the World.

Lu is the central figure in Imran's claims about a US-backed regime-change conspiracy that toppled his government through a no-confidence motion.  

The PTI chief shrugged off queries on evidence and raised the matter with the authorities concerned.

The cipher had been presented in the cabinet and a meeting of the National Security Council (NSC), and he replied to a query delay in making it public.

Asked if he had gotten in touch with the US president or state secretary regarding the matter, he did not answer, saying: “The NSC meeting decided to issue a demarche and a protest was registered to the US in Pakistan and Washington.”

He said he had a ‘perfectly good relationship with the Trump administration. It's only when the Biden administration came, it coincided with what was happening in Afghanistan and for some reason, which I still don't know,  they never got in touch with me."

Regarding Russia tour, the premier said: “The visit was planned a long time back and all stakeholders in Pakistan were onboard. We wanted oil, there was a gas pipeline which was being negotiated for the past six years before my government came in ... how would I have known that the day I land in Moscow, President Putin would decide to go into Ukraine?"

He claimed that the PTI would become the "biggest party in Pakistan's history because people are so incensed and feel insulted that these criminals have been imposed on them. “There is anger in Pakistan ... there is anti-Americanism".
