Mahagathbandhan (Uttar Pradesh)
The Mahagathbandhan (or Grand Alliance), or MGB, or simply the Gathbandhan (Alliance), was an anti-Congress, anti-BJP, Indian political alliance formed in the run-up to the 2019 general election under the leadership of two former Chief Ministers of Uttar Pradesh, Akhilesh Yadav of the Samajwadi Party and Mayawati of the Bahujan Samaj Party, along with Ajit Singh's Rashtriya Lok Dal. The Mahagathbandhan left 2 seats in Uttar Pradesh for Congress president Rahul Gandhi and his mother Sonia Gandhi to run in and Mayawati declared its support for the two.
