Former Pakistan prime minister Imran Khan has said that the country will break into three pieces if it loses nuclear deterrent capability due to wrong calls made by the "establishment".

He also warned that Pakistan would descend into a civil war if elections were not announced.

"If the establishment doesn't make the right decisions then I can assure in writing that [before everyone else] they and the army will be destroyed because what will become of the country if it goes bankrupt," Khan said in an interview, reports Dawn.

The establishment in Pakistan refers to the deep state cooperative federation of the Pakistan Armed Forces, the Pakistani intelligence community and other pro-military government officials and civilians.

"Pakistan is going towards a default. If that happens then which institution will be [worst] hit? The army. After it is hit, what concession will be taken from us? Denuclearisation."

"If Pakistan were to lose its nuclear deterrent capability, it would be fragmented into three pieces," he said.

"If the right decisions aren't made at this time then the country is going towards suicide," he warned.

Khan was removed from office in April through a no-confidence vote but he refused to accept the outcome and blamed that the US was involved in toppling his government.
