USA: Mueller Investigation: Russian tycoon's son-in-law Alex Van Der Zwaan admits lying to US election investigators

The son-in-law of a Russian oligarch has pleaded guilty to lying to investigators looking into Russian interference in the 2016 US election.

Dutch lawyer Alex Van Der Zwaan, 33, admitted to the US District Court in Washington he misled US Special Counsel Robert Mueller's office about communications with political consultant and lobbyist Rick Gates.

Mr Gates was deputy to Paul Manafort, the former campaign manager for Donald Trump in the run-up to the presidential election, who has also been indicted.

London-based Van Der Zwaan is married to the daughter of German Kahn, a Ukrainian-Russian billionaire who made his money in oil and is one of Russia's wealthiest men.

The lawyer admitted he lied to FBI investigators about conversations related to a report he helped prepare on the trial of a Ukrainian politician, Yulia Tymoshenko, as part of his work for Ukraine's justice ministry.
