Catalan Leader threatens Spanish PM to declare formal independence if no dialogue

In another exchange of letters between the Catalan Leader, Carles Puigdemont, and the president of the Spanish government, Mariano Rajoy, the hard-line stance by the former has remained unshakable. 

In the formal letter sent to Rajoy, the Catalan president admits that the declaration of independence was not voted in Parliament and remains suspended, however, he warns Rajoy that if he persists in preventing dialogue, the Parliament will declare independence.
