The Ukrainian Prosecutor General's Office (PGO) has received Spain's refusal to extradite ex-Finance Minister Yuriy Kolobov. The PGO will appeal the decision.

"Yes, we have received an official refusal of extradition," Head of the PGO Special Investigations Department Serhiy Horbatiuk told Interfax-Ukraine.

Horbatiuk said this was the response to the PGO's request and that the decision is not final.

"We will again appeal for extradition," he added.

Kolobov is suspected of committing a criminal offense under Part 5 of Article 191 of the Criminal Code of Ukraine (misappropriation, embezzlement of property, abuse of office). He was arrested in the resort town of Altea in the autonomous region of Valencia (Spain) in early March 2015.
