The BJP's victory in the 2025 Delhi Assembly elections was largely attributed to the Yamuna pollution issue, with the party successfully capitalizing on the backlash from Haryanvi-origin voters who perceived AAP's narrative on the river's pollution as an attack on their home state. The BJP's campaign focused on presenting itself as both the protector of Haryana's honor and the party with a concrete vision for the Yamuna's revival, ultimately leading to AAP's significant decline in the Yamuna belt and rural areas.
