Greece fully supports Spain's territorial integrity and sovereignty and not unilateral actions, Greek government spokesman Dimitris Tzanakopoulos said on Saturday commenting on Catalan's unilateral declaration of independence.

"We are very worried about the situation in Spain and we repeat that Europe can only move forward united. Unilateral actions cannot be accepted," Tzanakopoulos stressed in an e-mailed press statement issued after the Catalan parliament voted on Friday to proclaim the region's independence.

"We fully support Spain's territorial integrity and sovereignty, but also any initiative to restore democratic dialogue in the framework of Spanish Constitution," the Greek official said.

The Spanish government stripped the region of its autonomy after its controversial independence vote in parliament Friday, effectively taking charge of its government.

Spanish Prime Minister Mariano Rajoy announced the dissolution of the regional parliament and the removal of the Catalan leader, with an official state bulletin handing control of Catalonia to Spain's deputy prime minister Soraya Saenz de Santamaria.

Snap elections were called in the region, which also saw its most senior police officials dismissed and demonstrations for and against independence running on into the night.
