British law enforcement are looking into a $630,225 donation made in 2018 by London art dealer and former Conservative party treasurer Ehud Shedeg to the party before its landslide 2019 victory, the New York Times reports. Barclays Bank flagged it earlier this year as probably having actually comes from Shedeg’s wealthy father-in-law, Russian oligarch Sergei Kopytov, who served as a politician in the former pro-Kremlin Ukraine regime and owns a network of hotels and real estate across Russia and Crimea. “We are able to trace a clear line back from this donation to its ultimate source,” Barclays wrote in their report to UK authorities. Republican United States Senators Rand Paul and Ron Johnson were unavailable for comment on the New York Times story.
