BARCELONA, Spain (AP) — The Spanish government is activating a previously untapped constitutional article to take control of the Catalonia region in a bid to stop a rebellion from separatist politicians. Prime Minister Mariano Rajoy's Cabinet is meeting Saturday to outline the scope and timing of the measures the government plans to take under Article 155 of the Spanish Constitution. The article allows central authorities to intervene when one of Spain's 17 autonomous regions fails to comply with the law. Rajoy could force the removal of Catalan officials and call early regional elections for as soon as January. Opposition parties have agreed to support him in revoking Catalonia's autonomy.
