The Sena had in December sacked Rawale, its senior leader and five-time Lok Sabha MP from Mumbai, for dissidence.
The expulsion was ordered shortly after Rawale addressed a press conference in which he launched a no-holds-barred attack on the party leadership and alleged that Shiv Sena was becoming "a party of touts".
The development had come just four days after a stern warning by Shiv Sena president Uddhav Thackeray that all those who did not like his leadership were "free to leave the party".
Rawale made an appearance on stage at a rally in South Mumbai this evening, in presence of Uddhav.
