An Austrian MEP has accused Hungary and Poland of harbouring political "Brexit suspects" who sow divisions within the European Union (EU).
Othmar Karas, a member of the conservative European People's Party (EPP) bloc, made the accusation in a forthright speech to the European Parliament on Friday in which he also attacked the UK for daring to leave the EU.
"We must also learn the consequences from Brexit in the debate over the future of Europe," he said. "We must learn the lessons from Brexit in the way we deal with one another.
"There are many Brexit suspects amongst us in Hungary and Poland and other member states," Karas added. "Those who break shared laws and play off the interests of their citizens are not contributing to securing a common future."
The two former Eastern Bloc nations wrung concessions from Brussels earlier this month when they forced the removal of "rule of law" clauses from the EU's 2021-27 budget bill by threatening to veto the legislation. That prompted Hungarian-born US billionaire George Soros - a major funder of political NGOs - to accuse the EU of "surrender".
Both countries have come under attack from EU apparatchiks over their programmes of judicial reform, and have also refused to accept the bloc's quotas for accepting minimum numbers of asylum seekers during the Mediterranean migrant crisis.
While the Polish and Hungarian governments have not overtly threatened to follow the UK out of the door, several EU countries have significant Eurosceptic movements and parties - even core member states like Italy, the Netherlands, France and Germany.
Karas is a member of the Austrian People's Party (ÖVP) of Chancellor Sebastian Kurz - whose government takes a similar anti-immigration stance to Hungary and Poland, and has adopted a so-called "burqa ban" on face coverings in public that is widely seen as targeting Muslim women.
The MEP also laid into British Prime Minister Boris Johnson's government - as the clock ticked down to a no-deal Brexit - and attempted to drive a wedge between the Brexiteer PM and the Leave-voting majority.
"Withdrawals do not solve problems," Karas said. "None of the Brexit promises can be delivered except for withdrawal, and that is a defeat."
Karas attacked Johnson for seeking a free-trade agreement with no strings attached in the form of 'regulatory alignment' and continued European rights to the lion's share of the catch in the UK's vast fishing waters. "On the other side of the Channel, unfortunately, what has been asserted is a form of tactics made up of cherry-picking and arrogance and duplicity to their own citizens," he said.
