(CNN) Spain faces a week of deep political uncertainty as the secessionist leader of Catalonia considers whether to make a unilateral declaration of independence, against the backdrop of a bitter standoff with the central government in Madrid. Catalan President Carles Puigdemont had been expected to make a formal declaration at a specially convened session of the Catalan parliament on Tuesday. But there was intense speculation on Monday about whether Puigdemont would go ahead with such a provocative move -- particularly in the light of a huge rally against independence in Barcelona at the weekend that exposed deep misgivings about his tactics among some sections of Catalan society.Barcelona mayor says, "Escalation will not benefit anyone"Deep divisions over the issue of Catalan independence
