"There's more to be revealed about how the regime was ousted," Hamza said while speaking to columnist Muzamal Suharwardy on Saturday.
The journalist had asked Hamza to comment on the recent statements by Pakistan Muslim League-Quaid (PML-Q) leaders Moonis Elahi and Pervez Elahi on siding with Pakistan Tehreek-e-Insaf (PTI) during the no-trust move against the party's chairman Imran Khan this April.
Imran was removed from the prime minister's office as a result of the aforesaid Parliamentary motion.
At the time, he had termed the development a conspiracy against him to force him out of power.
The PML-N is now gearing up for a strong participation in the possible forthcoming Punjab elections, daring the PTI chief to attempt to dissolve provincial assemblies as per his earlier claims.
