Catalan declaration of independence
On 27 October 2017, a resolution based on the "Declaration of the representatives of Catalonia" declaring the independence of Catalonia was voted in the Parliament and was approved with 70 votes in favor, 10 against, and 2 blank votes. Fifty-three MPs from the opposition refused to be present during the voting after the legal services of the Catalan Parliament advised that the voting could not take place, as the law on which it was based had been suspended by the Spanish Constitutional Court. The two pro-independence parties, JxSí and CUP, had 72 seats, and the vote in favour of independence obtained 70.
Catalan nationalism
Currently, the main political parties which define themselves as being Catalan nationalists are "Convergència Democràtica de Catalunya", "Unió Democràtica de Catalunya". The "Esquerra Republicana de Catalunya", although deriving from nationalism, refuses the term "nationalism" and prefers to describe itself as pro-independence; so does "Soldaritat Catalana". These parties obtained 50.03% of the votes in the 2010 election. Within these parties, there is much divergence of opinion. More radical elements are only content with the establishment of a separate Catalan state. In contrast, more moderate elements do not necessarily identify with the belief that protection of Catalan identity is incompatible within Spain. Others vote for these parties simply as a protest and do not necessarily identify with the overall party platform (for example, some people may vote for ERC because they are simply tired of CiU, even though they do not actually desire a leftist Catalan republic). The other way around also occurs: some voters may vote for non-nationalist parties (especially the Initiative for Catalonia Greens, ICV, and the Socialists' Party of Catalonia, PSC) for reasons of policy, ideology or personal preference, although they share a nationalist viewpoint regarding Catalonia's status within Spain. Some polls, conducted in 2010, show that more than a third of PSC and more than half of ICV voters support Catalonia's independence (in the latter case, the percentage is even higher than among Convergence and Union voters); according to these polls, even 15% of the pro-Spanish Partido Popular voters in Catalonia support the region's independence.
