Orbán to visit US to try to broker another Putin summit but questions raised over motives

Hungarian PM also seeking exemption on US sanctions on Russian oil as he faces domestic challenge before elections

Viktor Orban will visit the White House on Friday as Hungary's far-right prime minister tries to broker another summit between Donald Trump and Vladimir Putin that Orban's advisers claim could help end the war between Russia and Ukraine.

Orban, who has proposed hosting the summit in Budapest, will also seek an exemption from US sanctions against Russian energy in what will be a major test of Trump's tougher line on the Kremlin after he accused Putin of slow-rolling negotiations to end the conflict.
