Catalonia and Spain continue to exchange barbs after Sunday's referendum.
Catalan President Carles Puigdemont says it could declare independence very soon, while Spanish Prime Minister Mariano Rajoy begs to differ.
The vote was ruled illegal by Madrid, with less than half of Spain's autonomous northern region being part of the voting process.
But those who participated voted overwhelmingly in favor of leaving Spain.
Catalonia's leader said he was in favour of mediation to resolve the crisis but the Spanish government had not accepted his offer.
In an interview with the BBC, Puigdemont said they will be able to act after getting all the ballots from overseas voters at the end of the week.
He accused Spain of authorianism, adding Madrid's refusal to negotiate left Catalonia "no other way" than to declare independence.
