Valentin Yumashev, the son-in-law of former Russian President Boris Yeltsin, who helped President Vladimir Putin come to power, has resigned as an adviser to the Kremlin.

Yumashev was an unpaid adviser with limited influence in Putin’s decision-making, but his departure removes one of the last links to Yeltsin’s rule within the Putin administration, Reuters reports, Klankosova.tv reports.

Utin ordered his armed forces to attack Ukraine on February 24 in an invasion that NATO’s military alliance says is an act of unwarranted aggression and that Russia calls a “special operation” needed to protect Russian-speakers in eastern Ukraine. .
