After Germany, Britain has also been criticizing Kosovo politicians, demanding from them progress in the dialogue with Belgrade, according to the daily Blic.

The paper said it learned "from diplomatic sources" that such a message was given to Kosovo Prime Minister Isa Mustafa and President Atifete Jahjaga by Baroness Joyce Anelay, special advisor of British Prime Minister David Cameron.

"Cameron's advisor last week in Pristina clearly told Jahjaga and Mustafa they must be more cooperative in the dialogue with Belgrade. It simply has to happen. On the other hand, the British are satisfied with the behavior of Belgrade in the dialogue with Pristina," according to the Belgrade-based daily's diplomatic sources.

In the same week when Anelay visited Kosovo, Serbian Prime Minister Aleksandar Vucic "received a letter from her boss himself," the paper said, referring to David Cameron.

In the letter, Cameron "praised Vucic's leadership and welcomed his efforts to improve relations in the Western Balkans, stressing the contribution in the dialogue with Pristina."

According to the article German Chancellor Angela Merkel previously asked Pristina to "fulfill three conditions: continue the dialogue, compromise with Belgrade and form a special court for crimes committed by the KLA."
