The day after BJP's historic victory in West Bengal, Mamata Banerjee refused to resign as chief minister, alleging a conspiracy between the Election Commission and BJP to rig the elections through Systematic Irregularities and Rigging (SIR). She claimed she did not lose but was defeated, and vowed to fight like a lioness. BJP called her stance a laughing stock and prepared for government formation on May 9, with Amit Shah appointed as central observer. In Tamil Nadu, TVK's Vijay sought Congress support to form government, with Congress likely to back him. Internationally, Iran attacked UAE for a second day, injuring three Indians, drawing condemnation from India and the US. Trump congratulated Modi on the Bengal win.
