Shiv Sena chief Bal Thackeray's daughter-in-law Smita Thackeray may soon join Congress, a Maharashtra Pradesh Congress Committee spokesperson said on Tuesday.

"Smita Thackeray is on way to joining the Congress," MPCC Spokesperson and former minister Hussain Dalwai told PTI.

Asked when would Smita, a film producer and social worker, join Congress, Dalwai said, "I cannot tell exactly when she would join but she is on way to joining the party".

Forty eight-year-old Smita is reportedly peeved at being "marginalised" in the Thackeray household and feels that the Sena is being "unfair" to Maharashtrians with its parochial politics.

The MPCC spokesperson said, "The fact that Smita is on way to Congress shows that after Bal Thackeray there is no one in Sena whose leadership people trust."

A member of Thackeray joining Congress is a significant development, he said.

"Anyone who is ready to abide by the ideology of the party and has faith in leadership of Sonia Gandhi is welcome in the party," Dalwai added.
