"Don't indulge in indiscipline in my presence, otherwise I will blacklist you," a miffed Mulayam told a youth convention here.
The Samajwadi Party (SP) leader was irked by the raising of slogans by youth workers when he went to deliver his address. The youth workers also tried to move towards the dais, leading to chaos.
As the party workers kept raising cries of "zindabad", Mulayam said, "Those who do not want to listen to me should leave. Those who raise slogans will be removed from the venue."
"You have no idea how much insult and difficulties I have experienced in the process of creating this party," he further said.
Referring to some youth leaders who were sacked for anti-party activities during the recent panchayat polls, the SP leader said, "We sacked some leaders due to compulsion and took them back after they regretted their mistake."
Mulayam also told the audience that he was "not a dictator".
