He said his supporters "will not sit back" until they get one.

Nawaz, who is currently in London, made the remarks in a virtual address at a convention of PML-N's parliamentarians and ticket-holders, saying that the country was facing "defining moments", reports Dawn News.

"Who should I hold responsible for this? Just Imran Khan or those who are really responsible?" he was quoted as saying by Dawn News.

"Imran's selectors, you will have to answer for this. You cannot go home without answering," Nawaz declared. "Without Pakistan's parliament, its institutions cannot operate. Even the judiciary cannot work. We will make you answer, we will not sit back until we get one."

"You (PML-N leaders) had won the election, but he was given victory. The tabdeeli person," Nawaz said, referring to PM Imran and added that those who "rigged" the 2018 general elections, had "violated the Constitution and committed a crime".

"We are not sheep that can be herded and if this has been happening [in the past], it will not happen anymore! We will make Pakistan a respectable country," he vowed and added that any member who "was scared should sit at home. We don't need cowards. You don't deserve to be in the assemblies if you are scared".

Nawaz also criticised the PTI government for "begging" other countries for money even though they had promised not to do so.
