This is Andrii Palchevsky, a prominent figure in a pro-Russian camp in Ukraine and a candidate for the upcoming mayoral elections in Kyiv (more on this here: How pro-Russian forces meddle in local elections: case of Kyiv).
He is seen here promoting the most popular of #KremlinNarratives among pro-Kremlin agents in Ukraine – “Ukraine is governed from the outside” – that also serves as a good platform for his bid to govern Kyiv.
