Last week, MLA Alina Saldanha resigned from the Assembly and the ruling Bharatiya Janata Party to join the Aam Aadmi Party (AAP) in New Delhi.
Meanwhile, in a major blow to the Congress, MLA from Curtorim Aleixo Reginaldo Lourenco resigned from the party as well as the state Assembly to join the TMC on Tuesday.
The Congress now has only two MLAs in the 40-seat Goa Assembly, down from the 17 MLAs that it had after the 2017 Assembly elections.
