"Come what may, we won't allow the removal of the 30x30 feet chowthara (platform)," Sena legislator Eknath Shinde told reporters.
Referring to the large number of Shiv Sainiks from Mumbai, Thane and other places who had come to Shivaji Park,Shinde said they would not budge from the venue and also foil attempts to remove the structure.
Maharashtra Chief Minister Prithviraj Chavan said permission for the funeral of Shiv Sena chief Bal Thackeray at Shivaji Park in Dadar was "conditional".
"The permission given for funeral at Shivaji Park was conditional. The fact that notices have been issued to the Mayor and Shiv Sena MP Sanjay Raut to remove the make-shift memorial means that the process of action is on," Chavan said.
When asked what would the state government do if the make-shift memorial of Thackeray was not removed from Shivaji Park, he refused to reply, saying, "You don't expect me to answer this question here."
On the proposed statue of Chhatrapati Shivaji Maharaj in the Arabian sea, the chief minister said the process to seek permission from the environment ministry was on.
Earlier, Chavan had said that the state government would not do anything in violation of the law with regard to Sena's demand to set up a memorial at the spot, as the matter with regard to Shivaji Park, which has been declared as a silence zone, is pending in the High Court.
While the government is of the view that it is a recreation ground, the court says it is a playground in which case no construction will be possible, he had said.
Uddhav asks Shiv Sainiks to take on challenges
Asserting that he knew how to run Shiv Sena, founded by his late father Bal Thackeray, party executive president Uddhav Thackeray has appealed to sainiks "to take on the challenges lying ahead".
"We will strive hard to fulfil Balasaheb's dream of unfurling 'bhagva' (saffron) atop state Assembly. We will fight for the cause of Marathi manoos and Hindutva," Uddhav said while addressing a rally of Shiv Sena workers from North Maharashtra .
Uddhav is on the state tour even as the party is fighting for the Shiv Sena patriarch's memorial at Shivaji Park, where he was cremated, in Mumbai.
Thousands of party workers, including women, from the region participated in the public meeting. Uddhav, who recently said that he could never claim the exalted title of "Shiv Sena Pramukh" that had been attributed to his late father, told the gathering that he knew how to run the party affairs.
"I was taught by Balasaheb how to run the party. I see my father in each and every Shiv Sainik. It's the time to take on the challenges lying ahead for us and not mourn over Balasaheb's demise," he said.
