HUNGARY’S re-elected Prime Minister Viktor Orban could be planning a “Stop [George] Soros” package clamping down on non-governmental organisations (NGOs) funded by foreigners, a spokesman for his Fidesz party said today.

The move could inflame tensions with the European Union, which has already taken his government to the European Court of Justice over its bid to close the Central European University, an institution founded by the Hungarian-US billionaire which Budapest views as a propaganda base.

Mr Soros uses his Open Society Foundations philanthropic fund to promote his political views, which range from support for “free markets” and the liberalisation of drug laws through promoting euthanasia to regime change in Zimbabwe.

Fidesz and its Christian Democrat coalition partners have won a two-thirds majority in parliament that will allow it to make constitutional changes.

Details of the “Stop Soros” package are unclear, but it would probably involve a clampdown on all NGOs supporting “illegal migration,” with Mr Orban having won re-election on a pledge to take measures including levying a 25 per cent tax on foreign donations to charities and bans on activists approaching Hungary’s external EU border, where many have tried to help refugees fleeing war and genocide in the Middle East.

Mr Orban has accused the EU and the United Nations of planning to turn Hungary into “an immigrant country.”

His xenophobic rhetoric was shared by the far-right Jobbik party, which came second in the election with 20 per cent of the vote and 26 seats. A social-democratic coalition, MSZP-Dialogue, was shunted into third place.

Mr Orban’s victory was welcomed by hard-right European governments in Warsaw and Vienna, as well as by German Interior Minister Horst Seehofer, who has previously clashed with Chancellor Angela Merkel over the number of refugees allowed into the country.

Mr Seehofer, chairman of the Christian Social Union, which replaces Ms Merkel’s Christian Democrats in the Bavarian Free State, warned the EU not to respond to Mr Orban with “arrogance and paternalism.”

But Luxembourg Foreign Minister Jean Asselborn said the victory showed “a taste for undermining values and scaremongering” and it would be “up to Germany and France” to “neutralise this tumour.”
