The murdered Russian opposition leader Boris Nemtsov will be laid to rest on Tuesday at a cemetery in southwest Moscow.
But first his body will lie in state followed by a memorial service at the Sakharov, Centre allowing mourners to pay tribute.
Fifty-five-year-old Nemtsov was gunned down outside the Kremlin in a drive-by shooting on Friday.
He was a charismatic figure within Russian politics, and a liberal reformer who rose to prominence under Boris Yeltsin and became a fierce critic of Vladimir Putin.
His death has provoked both national and international condemnation.
Thousands of Muscovites rallied on Sunday during a march held in his memory.
