"There is a ministerial agreement [at the Foreign Ministry of Ecuador], according to which Julian Assange was appointed Ecuador's diplomatic representative in Moscow," Vintimilla said.
According to the lawmaker, the Ecuadorian authorities "had first to wait for London to agree for Assange to be part of Ecuadorian diplomatic service in the city [London], but they had ready a ministerial agreement, which would have him move to Moscow as a representative of Ecuador."
"However, since he had no diplomatic immunity to leave the embassy, he could not go to Moscow," Vintimilla said.
After London refused to grant Assange diplomatic status, Suarez personally voided the agreement which would allow the WikiLeaks founder to work in Moscow. It happened on December 29, 2017.

Assange has been staying at the Embassy of Ecuador in London since 2012, unable to leave for fear of being detained by the UK authorities.
Since 2006, WikiLeaks, founded by Assange, has revealed a vast number of classified documents, including sensitive information allegedly related to US diplomats and the American intelligence community. This has led to a criminal investigation into its activities, initiated by US authorities.
