Fidesz MEP Csaba Dömötör said that although opposition Tisza Party leader Peter Magyar may deny it, various resolutions and statements "prove that Brussels wants to fast-track Ukraine's EU accession".
Dömötör told Hungarian journalists in Brussels on Tuesday that certain Hungarian politicians, including Magyar, were attempting to brand the accession moves as "a lie" and "not even possible", yet European Commission President Ursula von der Leyen recently said in Kyiv that Ukraine could become an EU member before 2030.
Dömötör said: "What's this if not fast-tracking?"
Also, EU enlargement commissioner Marta Kos has started to campaign to gain support for Ukrainian membership, he added, citing her as saying that Ukraine would become deeply integrated into the European economy "no matter what".
Dömötör cited her as saying that this was "already happening" and "we will speed it up". Domotor insisted that the EU wanted to accelerate Ukraine's integration into parts of the single market.
The commissioner also talked of how the EU was "aware of the consequences" for Ukraine's neighbours, including Hungary, Poland and Slovakia.
The Fidesz MEP said the screening process was taking place "with unprecedented speed" and the Commission was helping Ukraine full steam ahead.
"The enlargement plans are a priority for the Commission," he said, adding that they were not even holding a debate on the matter and failing to address basic questions such as the consequences of admitting "a country at war and full of weapons" to the bloc.
Dömötör said no questions were asked about the burden to the EU budget or the budgets of member states, or indeed what impact all this would have on European agriculture and Hungarian farmers.
He cited the "European Commission-funded" Jacques Delors Institute as estimating that funding for Hungary is shrinking by 15-22 percent.
"But they say not a word about this in the European Parliament," he added.
"What we're seeing is a highly elite policy implemented by excluding voters..." he said.
