Catalan secessionists are working towards a unilateral declaration of independence from Spain that could be adopted next week in defiance of a court order and increased economic pressure from Madrid.
After Spains Constitutional Court suspended a session of the Catalan regional parliament set for Monday, which had been expected to endorse an independence declaration, the parliament said pro-independence leader Carles Puigdemont would address the assembly on Tuesday.
Madrid has apologised for police use of violence in trying to hinder a weekend referendum it had declared illegal.
A Catalan legislator was quoted by El Mundo newspaper as saying secessionist parties in the Catalan parliament were discussing an independence declaration to be submitted to the assembly next Tuesday.
The stakes are high for the eurozones fourth-largest economy. Catalonia is the source of a huge chunk of its tax revenue and hosts multinationals from car-maker Volkswagen to drugs firm AstraZeneca.
