The cricketer-turned-politician called Punjab Chief Minister Bhagwant Mann as "akhbari mukhyamantri" for giving big ads in papers.
"Whenever dictatorship came in the country, a revolution came and today, I say the revolution's name is Rahul Gandhi," Sidhu said. "Today democracy is in chains, there is nothing like democracy today. Institutions have turned slaves and these have been made rubber 'ke gudde' (dolls)," he said.
He later met the parents of slain singer Sidhu Moose Wala at their residence in Punjab's Mansa district on Monday.
Navjot Sidhu resigned as the Punjab Congress president last year after the party received a drubbing in the assembly election. Sidhu took the step after Congress Chief Sonia Gandhi had asked him to. He was replaced by Amarinder Singh Brar (Raja Warring).
