Well, that could be anyone, paid by anyone, doing whatever... The fact is that Ukraine elections have been made impossible due to war. Ukrainian constitution does clearly state that being a war is a situation in which elections are not an option.
But let's not play naive here Branko, it is impossible to call elections with the Kremlin waiting for the occasion to disrupt and manipulate - which is the only reason you are asking for them.
We had elections in Croatia during war
https://en.wikipedia.org/wiki/1992_Croatian_parliamentary_electionRussia had elections during the war, and my info sources [paxmao + Ukraine media] assure me that Russia was getting severely punished the whole time. They are losing 10 soldiers for ever one which Ukraine loses. For the last several years, in fact, they have been out of weapons and fighting with shovels. The are even so low on food that they are eating dogs which have been eating dead Russian soldiers. Must be rough for them! But somehow they manage to vote? Go figure.
My country, the U.S., is very peaceful and has never been in a war so we don't know if war would stop our elections or not.
