"I have written to the Government today asking for a special postage stamp in honour of Balasaheb Thakre (Bal Thackeray)," he tweeted yesterday.
Swamy's demand comes at a time when the Sena is celebrating golden jubilee year of its foundation.
The move by Swamy, who merged his Janata Party with BJP ahead of Lok Sabha elections last year, is being seen as an attempt to revive his more than three-decade-old ties with Shiv Sena, which is the junior partner in the Fadnavis Government in Maharashtra.
The 75-year-old former Union Minister twice represented the Mumbai North-East constituency in Lok Sabha (1977 & 1980) on Janata Party ticket.
Meanwhile, Sena MP Sanjay Raut yesterday reiterated the party's demand for naming the Mumbai Coastal Road project after Bal Thackeray.
Senior Sena leader and PWD Minister Eknath Shinde has supported the demand, saying the name of late Sena chief is synonymous with the modern history of the state.
