Trinamool Congress leader Mamata Banerjee, Samajwadi Party leader Akhilesh Yadav, and Rashtriya Janata Dal leader Tejashwi Yadav — three figures operating under the INDIA bloc umbrella — joined a march through Delhi on Monday, raising questions about alleged electoral irregularities and directing their demands for accountability at Prime Minister Narendra Modi, Union Home Minister Amit Shah, and the Chief Election Commissioner.

Facing a Supreme Court challenge brought by the opposition, alliance leaders called on authorities to uphold constitutional principles and pledged to continue pursuing legal redress.

Banerjee told reporters that the opposition's call for action rested on principles of human dignity and fairness, adding that those aligned with her position were pressing for accountability on humanitarian grounds. She also told reporters that a legal challenge on the matter over what the organisation describes as voting irregularities remains on the table.

Banerjee took part in the INDIA bloc gathering at the Constitution Club of India before heading back to Kolkata, with her party's MPs joining the procession toward the Supreme Court in her absence.

Akhilesh Yadav and Tejashwi Yadav were among the opposition figures who took part in a street mobilisation held under the INDIA bloc's name, where those gathered called on the BJP to address their coalition's listed concerns and voiced the view that democratic standards had been eroded under its governance. Akhilesh Yadav argued that democratic institutions could endure only once the BJP was no longer in office, and added that the party placed its trust in the Supreme Court to deliver a fair outcome. According to Yadav, the purpose behind the mobilisation was to uphold citizens' democratic rights and defend the Constitution.

Tejashwi Yadav directed accusations at both the BJP and the Election Commission, claiming the two bodies were acting to erode democratic processes, and added that his party was ready to bear any cost in defending those processes. He concluded his address with a pledge that democratic principles would be upheld and that dishonest conduct would carry repercussions, then turned to the question of how the protest site had been secured, alleging that RSS personnel had been positioned there alongside law enforcement officers.

Speaking on behalf of the opposition, he argued that what he characterised as authoritarian rule was something his side would not accept, adding that those responsible would be held to account by the public. The group declared that its members had joined together in defence of democratic governance and constitutional principles. He called for consequences to be imposed on those involved.
