Bulgarian President Rumen Radev, seen as a supporter of Russia, will not attend the NATO summit scheduled for July in Washington, his press office said Thursday.

Radev has turned down a government proposal to lead the country’s delegation to the summit, saying he was not consulted while it worked out the official position of the country and its commitments regarding the war in Ukraine, the office said.

The decision comes on the heels of heated debates between pro-Russian and pro-Western parties in Bulgaria about whether Radev, as the commander-in-chief of the military, should represent the country at the NATO summit.

A former general and fighter jet pilot who once led his country's air force, Radev has often been criticized by political opponents for his pro-Kremlin position in the aftermath of Russia’s invasion of Ukraine.

He sees no military solution to the war and has repeatedly criticized the Bulgarian government's military support for Kyiv, saying that sending military aid would extend the conflict. He has referred to those favoring military aid to Ukraine as "warmongers."

Delyan Peevski, who leads a liberal pro-Western party and is one of Radev’s harshest critics, called the refusal "a confirmation that Radev’s positions serve foreign, not national interests and are subjected to dependencies and ties in the East, contrary to the Euro-Atlantic values and principles."

Bulgaria, one of Moscow’s closest allies during the Cold War era, joined NATO in 2004. Although the presidential post is mostly ceremonial, it provides a strong platform to influence public opinion.

Large parts of the country's population of about 6.6 million share pro-Russian sympathies based on historical and cultural bonds between the two nations, according to surveys.
