"I am Balasaheb's son. He brought the party to this level. I assure you that I will take Shiv Sena one step ahead than my father," Uddhav said at a function here.
Internal power tussles have been witnessed in the Sena units at Nashik, Kolhapur and Auranagabad in the last few weeks, putting a question mark on the party's prospects.
Referring to the tussles, Uddhav said, "Some people are saying that Shiv Sena will end....But I am saying I will not sit quiet till it is taken one step ahead."
Stating that Shiv Sena was playing a role in the national politics too, he reminded that the party opposed the visit by Pakistani women cricket team and also the participation of players from that country in Hockey League in the wake of brutal killing of two Indian soldiers at LoC.
Uddhav also defended Mumbai police inspector Sujata Patil whose poem on riots at Azad Maidan last year had sparked off a controversy because of its tone.
"Why Patil could not have the same freedom of speech which the two girls from Palghar were supposed to have while opposing the shut-down of Mumbai on Facebook after Bal Thackeray's death," he asked.
