AAP chief Arvind Kejriwal challenged Union Minister Amit Shah and Congress MP Rahul Gandhi to drink Yamuna water in public, reiterating his claim that Haryana is poisoning it. He alleged ammonia levels spiked to 7 PPM, calling it a "deliberate conspiracy" to disrupt Delhi's water supply. Citing a Jal Board CEO’s letter, Kejriwal accused BJP of endangering Delhiites. Haryana CM Nayab Singh Saini threatened legal action, while PM Modi dismissed the claim, saying, "I drink the same water." With Delhi elections on February 5, access to clean water remains a major poll issue.

PM Modi, at a Delhi rally, rebuffed AAP’s claim that Haryana poisoned Yamuna water, asking, "Can Haryana BJP poison me?" He argued Yamuna water is consumed by judges, diplomats, and Delhiites, including himself, and called AAP’s remarks divisive and insulting to Haryana. AAP, led by Arvind Kejriwal, alleged that ammonia contamination in Yamuna water from Haryana posed a health risk, endangering Delhi residents. Modi accused AAP of electoral fear-mongering and vowed BJP’s “double-engine government” would address Delhi’s long-standing issues. He also extended condolences for lives lost in the Maha Kumbh stampede earlier that day.

Union Home Minister Amit Shah strongly criticized Delhi Chief Minister Arvind Kejriwal for alleging that Haryana's government mixed poison into the Yamuna river. During a rally in Kalkaji, Shah challenged Kejriwal to provide evidence, disclose the Delhi Jal Board report, and name the alleged poison. Kejriwal's claim was earlier refuted by Delhi Jal Board CEO Shilpa Shinde as "misleading." Shah accused Kejriwal of scaremongering and breaking promises, urging voters to back BJP's Ramesh Bidhuri in the upcoming February 5 Delhi Assembly elections. Kejriwal countered by framing the polls as a choice between public welfare and corporate favoritism.

Uttar Pradesh Chief Minister Yogi Adityanath accused the AAP of creating fake Aadhaar cards for Bangladeshis and Rohingyas. He said this was done to settle illegal immigrants in Delhi and called it a "sin." Campaigning for the BJP ahead of the Delhi assembly elections, he slammed AAP’s “appeasement politics” and labelled the party as a "symbol of corruption and anarchy." Adityanath also criticised the AAP government for poor infrastructure in Delhi and claimed many residents are moving to Noida and Ghaziabad. He urged voters to choose a “double-engine government” and promised action against the so-called "Waqf mafia."

Aam Aadmi Party (AAP) chief Arvind Kejriwal launched the party’s manifesto for the 2025 Delhi Assembly elections, outlining 15 key promises under the theme ‘Kejriwal ki guarantee.’ These include job creation, increased financial support under the Mahila Samman Yojana, free medical treatment for senior citizens, and scholarships for Dalit students studying abroad. Kejriwal also promised to fulfill previous guarantees like 24-hour water supply and Yamuna cleaning, while extending benefits like free water, electricity, and bus rides to tenants. He criticized the BJP for copying AAP’s promise-based governance but claimed AAP delivers on its guarantees.

Congress president Mallikarjun Kharge questioned if taking a dip in the Ganga could end poverty. He accused BJP leaders of using faith for show during the ongoing Maha Kumbh in Prayagraj. Speaking at a rally in Madhya Pradesh, Kharge said, "Does this fill hungry stomachs?" He apologised if his remarks hurt anyone's faith but criticised spending money on such acts while the poor suffer. BJP leader Sambit Patra responded, calling Kharge's words anti-Hindu. He defended BJP leaders' faith and accused Congress of disrespecting Hindu beliefs. The comments have sparked a political row, with both parties trading barbs.

Union Home Minister Amit Shah has promised to remove illegal Bangladeshi infiltrators from Delhi and clean the Yamuna River within three years if the BJP wins the upcoming Delhi elections. At a rally in Narela, Shah criticized the AAP's governance and claimed that Delhi had worsened under Arvind Kejriwal’s leadership. He pledged the development of the Yamuna riverfront, similar to the Sabarmati. Shah also labeled AAP as the “Aawaidh Aamdaniwali Party” and accused them of corruption. The Yamuna’s poor state remains a major issue in the election campaigns.

Uttar Pradesh CM Yogi Adityanath called dividing society by caste, region, or language “nothing less than treason.” Speaking at Maha Kumbh 2025, he praised PM Modi for ensuring the rights of underprivileged groups in the last decade. Adityanath said schemes like free ration, housing for the poor, and electricity connections reflect the government’s commitment to unity and development for all. He warned against political attempts to divide people and urged followers of Sanatan Dharma to stay vigilant. Adityanath emphasised the need to strengthen India by ensuring justice for Dalits and backward communities without discrimination.

Union Home Minister Amit Shah criticised Delhi CM Arvind Kejriwal, calling him a liar who breaks promises. Speaking at a press conference, Shah said Kejriwal’s government failed to deliver on clean water, cleaning the Yamuna, and other promises. He accused Kejriwal of opening liquor shops near schools and temples and being involved in scams like the Liquor Scam and the Delhi Jal Board scam. Shah compared Kejriwal with PM Modi, saying the BJP works on fulfilling promises. He also mocked Kejriwal for not taking a promised dip in the Yamuna after claiming he would clean the river.

BJP New Delhi assembly candidate Parvesh Verma took a boat ride on the Yamuna, carrying a life-size cut-out of ex-CM Arvind Kejriwal. The cut-out depicted Kejriwal holding his ears with the slogan, "Main fail ho gaya... mujhe vote mat dena," referencing his unfulfilled promise of cleaning the Yamuna by 2025. Verma criticized AAP’s failures and proposed measures for cleaning the river. The issue of Yamuna pollution has become a central topic in Delhi’s 2025 assembly elections. Congress and Samajwadi Party also weighed in, criticizing BJP and AAP for politicizing river pollution.
