The PSOE is testing an alliance with ERC in Barcelona and stirring up the hornet's nest of pacts after the Catalan elections of 12-M. PSC Jaume Collboni loses the question of trust in Barcelona City Council and opens up to "expand" his Government with partners such as ERC JxCat Junts+ Puigdemont per Catalunya.

"If ERC acts as a crutch for the PSC in the City Council, it can also do so in the Generalitat," warned Josep Rius.
