RIA Novosti: Yumashev left the post of presidential adviser on a voluntary basis

The agency notes that Yumashev is also a board member of the Yeltsin Center.

“Yumashev has not been an adviser to the president since April ... He served as an adviser to the president on a voluntary basis,” Telen said.

According to the deputy director, Yumashev decided to step down of his own accord.

Valentin Yumashev led the presidential administration in 1997-1998.

On June 22, 2018, he was appointed as a pro bono presidential adviser.
