Footages on television channels showed angry PPP activist Imran taking his show and showing it to the law minister who was addressing party workers at the Circuit House in Hyderabad.
Imran who was later taken out of the place by security officials claimed he was upset and wanted to lodge his protest as the PPP leaders and ministers were immune to their problems.
"They don't provide jobs to us as promised by them during elections. They also didn't assist flood victims last year," he said.
The southern province of Sindh is considered the stronghold of the ruling party which derives it strength from the standing of the Bhutto family in Pakistan politics.
