Dutch Prime Minister Mark Rutte, a staunch ally of Kyiv and a critic of Russian President Vladimir Putin, will succeed Jens Stoltenberg as NATO chief, Dutch national broadcaster NOS reported Tuesday, after Hungary and Slovakia backed him.

Speaking at a news conference alongside U.S. Secretary of State Antony Blinken in Washington, Stoltenberg neither confirmed nor denied the media report.

"With the announcement of (Hungarian) Prime Minister (Viktor) Orban, I think it's obvious that we are very close to a conclusion ... to select the next secretary-general, and I think that's good news," he told reporters, while praising Rutte.
