The Spanish government has reached agreement with a major political party in the northeastern Catalonia region on greater self-government.

The leader of Catalonia's Convergence and Union Party, Artur Mas, reached the deal Sunday after several hours of talks with Spanish Prime Minister Jose Luis Rodriguez Zapatero.

Few details of the agreement have been announced. But it includes referring to Catalonia's "nationality" in the text of the accord.

It also grants the region greater control over its finances and tax revenue.

Spain's parliament must approve the new charter.

Many politicians in Catalonia have called for greater autonomy, with some demanding independence.

Spanish conservatives strongly oppose granting regions more power, saying the country could split apart.
