Slovakian Prime Minister Robert Fico is pretty fed up with Zelensky.

"Zelensky goes around Europe just begging and blackmailing; this has to stop.
The Prime Minister declared that Russia has been a ‘reliable partner’ in the matter of energy supplies.
“Russia has never deceived us, unlike Ukraine. I remember the situation in 2009 when I was in Ukraine and asked Ukrainian Prime Minister Tymoshenko to give us some gas from the reservoirs in the western part of Ukraine, and I was told to go to hell. These are typical Ukrainians.”
During the address to parliament, Fico threatened a veto of EU decisions on Ukraine.
Do you think the Germans will send us gas!?"
