After the 2012 regional election resulted in Convergence and Union (CiU) unexpectedly losing seats, President Mas was placed in a difficult political position, as he fell 18 seats short of the absolute majority. He was forced to sign an agreement with Republican Left of Catalonia (ERC), in which the latter pledged to support the government, albeit without entering a formal coalition, in return for a faster process to obtain the independence of Catalonia.
