The country's ruling Fidesz party has promised to launch a “national consultation” on the alleged plan by financier Mr Soros. The right wing party, which is preparing for elections next April, promised on Thursday to expose Mr Soros’s alleged plan, as it fights to be re-elected for a third term. Fidesz leaders claim Mr Soros wants Europe to accept one million immigrants annually for labour, according to the Financial Times. The ruling party asked Prime Minister Viktor Orban's government to carry out a probe about Brussels' plans to distribute asylum-seekers in the EU, a week after the EU's top court ruled against complainants Hungary and Slovakia.

Previous consultations have taken the form of sending out questionnaires to millions of voters, setting out the government's right-wing nationalist position and asking people if they agree. Mr Soros, who has spent a large part of his fortune funding pro-democracy and human rights groups, has been targeted by Mr Orban's government repeatedly. His spokesman has described the government's portrayal of his views on immigration as "fantasy". Mr Orban has been one of the loudest opponents of mandatory migrant resettlement quotas proposed by the EU, arguing this would undermine its sovereignty and social fabric.

The Prime Minister has been vocal that he too thinks that the billionaire has a plan to force Hungary to accept more migrants. His anger comes despite Mr Soros once funding a scholarship for him in 1989. Mr Orban’s stance has gone down well with voters, and Fidesz is firmly ahead in opinion polls. The Hungarian Prime Minister said EU officials will implement the alleged plan because they “eat from Soros’ hand”.

Goran Buldioski, director of the Open Society Initiative for Europe, part of a group of foundations created by Mr Soros, rejected the allegations. He said: “The challenges on migration faced at the moment have nothing to do with George Soros and the Open Society Foundations.” Lajos Kosa, a party vice chairman, said the national consultation should focus on the alleged Soros plan, something that would place migration at the centre of the campaign. Mr Kosa said: “The European Commission stops just short of saying that they carry out the Soros plan... but all their steps and ideas with regard to migration point in this direction," adding last week's EU court defeat for Hungary had "opened the gates".
