In parliamentary elections in Hungary this weekend, Prime Minister Victor Orbán's ruling Fidesz party has been returned to power with a large majority, although the final results are yet to be confirmed.
Hannes Swoboda, president of the Socialists and Democrats Group in the European Parliament, said:
"However big a majority Orbán has obtained, this does not absolve him from complying with EU law and respecting EU values.
"Mr Orbán has spent the last few years redrafting the constitution and passing laws that were frequently beyond what is acceptable in a European democracy.
"Therefore, the European Union must continue to closely monitor whether Mr Orbán's new government will respect European law. To this end, a monitoring group as proposed in the report adopted by the European Parliament in July 2013 should be urgently established."
"The increase in votes for the far-right Jobbik party shows that Mr Orbán's nationalist rhetoric does not counter extremism but encourages a worrying climate of hatred."
