Bulgaria's ambassador to Ankara Branimir Mladenov has resigned as pressure is piled up on the president to recall him.

According to members of the right-wing Blue Coalition, the president himself has advised Mladenov to submit his resignation and the same scenario is likely to develop in Washington in a day or two.

The news comes a week after the Bulgarian government approved the recall of the Ambassadors to Turkey and the USA, Branimir Mladenov and Lachezar Petkov, over violations in the Bulgarian Parliamentary Elections in July 2009 in the respective countries.

Parliament was to debate on Friday a declaration, calling on the president to recall the envoys, making in fact the first step in the efforts of the majority to impeach Socialist President Georgi Parvanov, but unexpectedly delayed it.

President Georgi Parvanov, whose signature is needed in order to actually recall the incriminated Ambassadors, however said he is not convinced that they are guilty and accused the government of excluding him from the investigation of their alleged violations.

The president said he first needed to see all evidence indicating the violations in question stressing that he would remove them if they were responsible.

Bulgaria's Prime Minister Boyko Borisov has made it clear he won't step back on his decision to recall the country's ambassadors to Turkey and the United States despite the president's disagreement. He has expressed confidence that Parvanov will finally embrace that decision.
