The other person familiar with Yumashev's thinking, who spoke on condition of anonymity, also said that Yumashev in April ceased to be a presidential advisor.
Under Yeltsin, who was Russian president from 1991 to 1999, Yumashev served as a Kremlin advisor and later as head of the presidential administration. He is married to Yeltsin's daughter, Tatyana.
He did not play a major role in decision-making as a Putin advisor, but he represented one of the few remaining links in Putin's administration to Yeltsin's rule, a period of liberal reforms and an opening-up of Russia towards the West.
