Slovak Foreign Minister: Feith's plan for north does not have EU standing behind it

"The mandate of Pieter Feith is to represent the EU, which means that he must represent all 27 member-states and respect the stance of every member-state," Lajcak told Deutsche Welle radio.

"I think that Feith realized this during his previous mandate, and I think that he can continue working in this position," Lajcak said.

Slovakia is one of the five EU countries that have not recognized Kosovo's unilaterally proclaimed independence.

Lajcak said that Feith's plan for "integration of northern Kosovo" - the Serb parts of the province that reject the UDI and the Albanian government in Pristina - does not have EU standing behind it.

"I don't know if that plan exists and how much authorization there is. It is certain that such a plan was never discussed, nor approved by the European institutions," he said.

Even though the EU reached an agreement to extend Feith's mandate in Kosovo, it has not been done yet officially. The final confirmation could occur on Thursday.

Meanwhile, besides his role of EU special representative, Feith holds another office - that of chief of the International Civilian Office (ICO), which was set up by the western countries who support the UDI.

It was in this latter role that the Dutch diplomat, along with Kosovo Albanian politicians, announced plans to "integrate northern Kosovo".
