Shivpal's aide and former minister Sharda Pratap Shukla said the new party will become a big force in the state.
The state government is set to take decision in this regard in the wake alleged threat to the life of Shivpal as has been claimed by him.
Notably, Shivpal Yadav, after a long wait following a spell of intense family feud and direct confrontation with nephew and former UP CM Akhilesh Yadav in 2016, launched his SSM last month.
The posters say the yatra will start at 7 am from Pachraha in Etawah and conclude at Numaish Maidan on October 2.
Some Samajwadi Secular Morcha insiders said the missing photographs in fresh publicity material were a reaction to Mulayam Yadav's literal snub to Shivpal Yadav.
Tej Narain Pandey also termed Shivpal, who recently floated his own outfit Samajwadi Secular Morcha, as "B team" of the BJP.
The estranged uncle of Samajwadi Party chief Akhilesh Yadav said the Morcha is for neglected socialists and unemployed youth.
He did not name his estranged nephew and SP president Akhilesh Yadav during his address at the programme but said, "Now a days people only eye posts".
Rajbhar, who has been critical of alliance partner BJP in the past, reiterated that the SBSP had no tie-up with Shivpal Yadav's Morcha and that the alliance with BJP will continue.
While interacting with media persons after making the announcement, Shivpal vowed to bring all those leaders who were feeling left out and neglected in the Samajwadi Party.
