The Indian judiciary was thrown into a turmoil on Friday when four senior Supreme Court judges convened a press conference to complain about "selective" case allocation by Chief Justice of India Dipak Misra and passing of certain judicial orders.
However, he added "it does not necessarily mean that the party is going to be a part of the march."
Senior CPI(M) leader Sitaram Yechury, Congress MLA Alpesh Thakor, Dalit activist Jignesh Mevani, quota agitation spearhead Hardik Patel, and MP and farmers' leader Raju Shetti are also likely to attend the 'Samvidhan Bachao' march, one of its organisers said.
Rebel JD(U) leader Sharad Yadav, and Tushar Gandhi, the great grandson of Mahatma Gandhi, have also been invited to participate in the march, he said.
"I was worried about BJP's constant attacks on the Constitution earlier and when the four judges went public, I decided to take some steps. I then decided to hold a march in Mumbai to save the Constitution and invite several leaders for it," Shetti said.
He said he called on several social and political leaders and proposed the march from the Babasaheb Ambedkar's statue at Mantralaya to the Gateway of India.
"We will sit at the Gateway of India for the whole day and observe silence as a mark of protest against the attacks on our Constitution," Shetti said.
Hardik Patel also said on his twitter handle that he would participate in the march on the Republic Day.
"I will be a part of #SaveConstitution rally in #Mumbai on 26Jan #Republic day. Country faces a serious threat to democracy and is inching towards #Fascism and we will not allow that to happen.... lets stand together and save our #Democracy and #Constitution," he tweeted.
