Video footage emerged on Tuesday showing Pakistan Muslim League-Nawaz (PML-N) activists chanting 'Go Nawaz Go' slogan on their way back from a public gathering in Peshawar on Sunday.
The ruling party chief addressed a huge crowd where according to reports there was a shortage of seats despite arrangement for 40,000 people.
The former prime minister responded to every slogan from the stage with mostly criticising the judiciary and his arch-rival, Pakistan Tehreek-e-Insaf (PTI) Chairman Imran Khan
However, video footage shows anti-Nawaz Sharif and pro-Imran Khan slogans being chanted by the crowd.
The video went viral on social media with 'Go Nawaz Go' and 'Imran Zindabad' being chanted.
Ameer Muqam, PML-N K-P president, could not be reached for his version on the footage despite repeated attempts.

Nasir Musazai, the party's former provincial secretary information, termed the video footage as nothing but "PTI propaganda".
“You can expect anything from them [PTI] since they were stunned by seeing the sea of people at the gathering,” Musazai told The Express Tribune.
He added that people could have been bribed into chanting the slogans.
The PML-N representative said that there was a sea of people at the venue with estimates of over 50,000 people.
