Latest: Spain brands Catalonia's response as inadequate and imposes Thursday deadline

Catalonia's leader has called for dialogue with Spain and a meeting with the country's prime minister, complying with a Monday deadline to respond to a request from the central government to state explicitly whether he had declared independence.

Update 10.45am: Spain's deputy prime minister has said that Catalonia's leader did not give an adequate response in his letter about the region's independence and has until Thursday to comply with the country's laws.

Carles Puigdemont's letter, issued two hours before a Monday deadline, did not clarify whether he in fact declared Catalonia's independence from Spain.
