The three parties entered talks in August 2014 to discuss their merging into a new political party, with all three sharing their political action in the ensuing months, such as their presence in the 2014 "V" Catalan Way or their joint public response to the 2014 Catalan self-determination referendum. As merger discussions continued, Avancem dropped out on 12 November, citing political disagreements with Moviment despite a "total agreement" existing with NECat. An agrement between NECat and Moviment was reached on 20 November, and ten days later both parties would officialize their merger into the newly-established "Left Movement" (MES).
