A senior Ukrainian lawmaker who put President Donald Trump forward for a Nobel Peace Prize has withdrawn his nomination.

Oleksandr Merezhko, the head of Ukraine's parliamentary foreign committee, told Newsweek on Tuesday that he had "lost any sort of faith and belief" in Trump and his ability to secure a ceasefire between Russia and Ukraine.

Merezhko said Trump had "virtually no reaction" to large-scale strikes on the Ukrainian capital in recent weeks, adding: "He has chosen the path of appeasement."
