Former Kremlin ideologue Vladislav Surkov has returned to the presidential administration.
The Kremlin said in a statement on September 20 that President Vladimir Putin has appointed Surkov as a presidential aide.
Surkov was first deputy head of the presidential administration from 2008 until 2011, when he was appointed a deputy Prime Minister.
He is widely seen as the architect of Russia's "managed democracy" under Putin.
Surkov resigned from this position in May this year after a public spat with the Investigative Committee, an agency closely associated with hardliners in the Russian leadership.
The Kremlin statement did not specify which areas Surkov is going to oversee, but Putin's spokesman, Dmitry Peskov, said the presidential aide would be responsible for social and economic issues in Abkhazia and South Ossetia, two breakaway Georgian provinces which Russia has recognized as independent states.
