Leader of the Hungarian party Jobbik party Gabor Vona urged Hungary to quit the European Union at a demonstration in central Budapest past weekend.

Vona said European Commission President Jose Manuel Barroso’s letter on Wednesday had violated Hungary’s independence. He called for a referendum to be held, enabling Hungarians to decide whether they still want to be part of the EU.

The crowd filling a 100-metre stretch of a 15-metre wide street was chanting “Let’s Quit” and Down with Trianon” in response to the party leader’s call.

By asking Hungary to amend three of its laws, the EC demonstrated that it expected Hungary to give up its independence, said Vona.

Several participants wore black military uniforms and boots and were carrying EU flags with the word NO written on them.

At the end of the rally Jobbik deputy leader Elod Novak and Levente Muranyi, whom he introduced as a 1956 freedom fighter, set an EU flag on fire.

The communications department of the Budapest Police Headquarters told MTI on Saturday evening that the police authority would file a report against two persons who burnt an EU flag at the Jobbik demonstration. The report about suspected vandalism will be submitted to the central investigation office of the chief prosecutor.

The EC said on Wednesday that it was analysing the compatibility of Hungarian laws with EU laws. Concerns relate to a number of issues, including the independence of the central bank, mandatory early retirement of judges and prosecutors and the independence of the national data protection authority, Barroso said in a statement.
