KYIV (Reuters) -Ask Ukrainians who the country's most powerful figure is after the president and many will say Andriy Yermak, his chief of staff and a key negotiator during four years of war when Western financial and military aid has kept Kyiv in the fight.
Yermak, a friend of President Volodymyr Zelenskiy and his trusted right-hand man, is ensnared in an evolving corruption scandal after anti-graft agents searched his property on Friday.
