"We will come to power on our own," Raj said, addressing party workers at the seventh anniversary function of MNS at Shanmukhananda Hall in Matunga here.
This is the second time in a month that Raj has ruled out a tie-up with Shiv Sena, led by his estranged cousin Uddhav Thackeray, in the State, where Assembly poll is due next year along with Lok Sabha election.
Responding to a query on whether the warring cousins could come together, Uddhav had said, "one cannot clap with a single hand. Tell me, can you?"
Raj left Shiv Sena in 2005 over leadership issues and formed his own party the next year. Last year, Raj fuelled speculation about a patch-up when he visited his ailing uncle, Bal Thackeray, several times.
On Tata Group Chairman Emeritus Ratan Tata driving to meet him at his residence yesterday, the MNS leader said "this is a good omen."
"Ratan Tata came. It is not only an honour accorded to me but to you (party workers) also. There was no specific occasion but he came. I consider it as a good omen," Raj said.
