[3] On 4 October 2011, Oriol Junqueras stated that Esquerra’s proposal was to integrate members of Solidaritat, Reagrupament and independents into its lists via an electoral platform, with the legal form of a coalition, such that the republican party would predominate in the candidacy.

[4] On October 8, 2011, Oriol Junqueras and Joan Carretero, the presidents of Esquerra and Reagrupament respectively, as well as Alfred Bosch, held a press conference in the Barcelona Athenaeum to announce the formation of an electoral coalition named Republican Left of Catalonia-Catalonia Yes (Esquerra Republicana de Catalunya-Catalunya Sí),[5] aimed at achieving Catalan independence and the preservation of the Catalan welfare state.

[6] The coalition agreement also left space on its lists for independents with connections to the Catalonia Yes citizens' platform, such as Miquel Sellarès, Gorka Knörr and Josep Cruanyes, among others.

[10] The platform put forward lists in the four electoral subdivisions in Catalonia, obtaining 256,393 votes (1.05% nationally, 7.06% of the total in Catalonia) for the Congress of Deputies, seeing three of its candidates elected, two for Barcelona (Alfred Bosch and Joan Tardà) and one for Girona (Teresa Jordà), thus becoming part of the mixed group of the lower chamber; this was the same number of seats obtained by ERC alone in 2008.

[11][12] In 2012, in preparation for the regional elections, ERC called a meeting with Solidaritat, Reagrupament, the CUP (which did not attend) and Democràcia Catalana [ca; es] to negotiate an electoral coalition.
