The regional parliament of northeastern Catalonia has approved a plan to set up road map for independence from Spain by 2017, in defiance of the central government.All 72 separatist lawmakers -- the majority in the northeastern region's parliament -- voted for a resolution aimed at creating an independent republic by 2017.The proposal was tabled by pro-secession lawmakers from the "Together for Yes" alliance and the extreme left-wing Popular Unity Candidacy (CUP). The groups together obtained a parliamentary majority in regional elections in September.Parties favouring independence from Spain won a majority of seats in the Catalan regional election in September. The Spanish constitution does not allow any region to break away, however, and the centre-right government of Spanish premier Mariano Rajoy, facing a general election in December, has said it will immediately seek to block the resolution in the courts.Rajoy was scheduled to speak later Monday.
