actually lost seats: the bigger winners were the independentist Republican Left of Catalonia (Esquerra Republicana de Catalunya (ERC), and the ecosocialists. Since CiU did not win an absolute majority, the combined forces of all three left parties allowed the change in government. While PSC maintained the post of President of the Generalitat (Maragall), ERC nominated the First Minister (Conseller Primer) — Josep-Lluís Carod-Rovira and, later on, Josep Bargalló. This first tripartite rule became an uneasy coalition due to tensions between the PSC and ERC and internal tensions between PSC and PSOE as well. The evidence of such an uneasy relationship was the controversial forging of the amendment to the Statute of Autonomy of Catalonia. The 2006 regional election saw Convergència i Unió (CiU) increasing its numbers, while both the PSC and ERC lost seats, but still was not enough of an increase for CiU to block the formation of a second left-wing tripartite coalition (PSC+ERC+ICV), again led by PSC's, this time being José Montilla the President of the Generalitat. Also this election saw a newly created party Ciutadans - Partido de la Ciudadanía entering the regional Parliament. The new century has also seen a revival of the Esquerra Independentista (pro-independence left), which has again regained some of its strength after the end of Terra Lliure in 1995. Its Popular Unity Candidacies Candidatures d'Unitat Popular have done well in the municipal elections of 2007, gaining over 20 town council members. The amendment to the Statute and current political issues Unlike the autonomous communities of Navarre and the Basque Country, Catalonia lacks its own tax system; thus the economic financing of the regional administration depends almost entirely on funds raised by national-government taxation and budgeted to Catalonia. This became a mainstream issue at the time of amending the Catalan Statute of Autonomy. From an economic perspective, the regional government aims to achieve a high degree of fiscal autonomy (based on the argument that the region pays in more to the national Spanish coffers than it receives, thus overlooking the "solidarity between regions" enshrined by the Spanish Constitution of 1978). There was a significant political controversy as a result of the Catalan parliament's proposed draft of a replacement Autonomy Statute which sought to define Catalonia as a 'nation'. Article 2 of the 1978 Spanish Constitution states that the constitution "is based in the indissoluble unity of the Spanish Nation (Nación)" while also referring
