The parliament in Spain's Catalonia has resumed activity for the first time since elections in December. The aim is to unblock the current political standstill. Some in Catalan's independence camp want former regional head Carles Puigdemont to govern from Brussels. They deride Madrid "authoritarianism". Others think a lower profile candidate would ease tensions. The latest survey showed the number of Catalans in favour of independence had dropped to a four-year low.
