Pakistan People's Party (PPP) leader Qamar Zaman Kaira demanded on Saturday that either Prime Minister Nawaz Sharif should reveal who was "conspiring" against him or step down immediately.
"Who is hatching these 'conspiracies' against you?" an infuriated Kaira asked while addressing a news conference on Saturday. "If you'll not name those who you claim are conspiring against you, you are committing a crime," he added.
Pakistan Muslim League-Nawaz leaders have been claiming that the probe into the Sharif family's offshore assets was a conspiracy and a politically-motivated move against the incumbent government and the country's stability.
Kaira said the premier should summon a meeting of the parliamentary parties to explain to them about the conspiracies allegedly being hatched against him.

"We don't see any such conspiracy against you," he added.
According to the politician, the prime minister also needed to reveal how he became wealthy so fast during his rule from 1990 to 1993 and why he had befriended Indian premier Narendra Modi.
"There is still time," Kaira said. "You should step down and we will save democracy."
Kaira reminded the Sharif that two of the top court's judges had issued a verdict against him, followed by the Joint Investigation Team's (JIT) report which had held his family responsible of hiding assets and forging documents.

The JIT formed by the Supreme Court to probe Sharif family's offshore assets had concluded on July 10 that the Sharif and his family was in possession of assets beyond their known sources of income.
The team, which submitted its report to the apex court, recommended filing a reference against the Sharif family with the National Accountability Bureau.
The PPP leader told the premier that he should not hide behind claims of being victimised. "You don't have to pretend that you are innocent after all of your looted wealth is exposed and your sons' properties resemble those of a monarch," he remarked.
