Catalonia’s president has called on European Union leaders for support as the region seeks a vote on independence in November this year, the source of an increasingly bitter fight with Spain’s central government.

Artur Mas urged European powers to encourage a referendum that the centre-right government of Mariano Rajoy says is unconstitutional and it will not allow. The Catalan struggle is likely to dominate the political agenda this year in Spain, which is slowly emerging from a recession and heading towards a general election in 2015.

“Contrary to some reports, there are a number of legal and constitutional options which allow this referendum to take place in Catalonia,” Mr Mas wrote in a 20 December letter to German Chancellor Angela Merkel, which was reproduced on his official website and is one of 27 sent to European leaders. “I am confident I can rely on you to encourage the peaceful, democratic, transparent and European process to which I and a vast majority of the Catalan people are fully committed.”

Scotland is due to vote on independence in September, though Mr Mas made no mention of the British parallel in his note.

Other than embarrassing Spain’s central government, the international campaign also has a tactical aim, with Catalan’s ruling party and citizens groups eyeing an end-game possibly played out in an international tribunal.

With Mr Rajoy and Mr Mas showing no signs of reaching a political negotiation, Mr Rajoy is expected to use the national parliament and supreme court to block any move to hold a referendum.

In that case, Mr Mas may well have to call early elections, likely to be won by a more radical independence party, the Catalan Republican Left (ERC), opinion polls show. ERC leaders say they will take their battle for a referendum to an international court if need be.

The regional government also sent 45 memos to foreign countries in December listing its attractions as an export-led economy at the heart of the EU – of which it wants to remain a member.

Opinion polls have shown mixed support for independence, with some recently showing only 35 per cent would vote for a full split from Spain. But polls have shown overwhelmingly that Catalans want the right to decide and believe that Mr Rajoy should authorise a vote.
