Jobbik, a non-parliamentary radical party which polls indicate will win at least one seat in the European Parliament, is calling for a change of government and for Hungary's ruling politicians to be "held to account", the party's leader, Gabor Vona, said on Wednesday.

Vona, speaking at a news conference alongside Geza Gyenes, chairman of the Hungarian Doctors' Association, insisted that the duty of the next government -- which polls suggest will be the current conservative opposition Fidesz -- is to create the conditions for "social catharsis" by "holding politicians to account".

Vona said that Hungary's health-care system, in particular, had suffered at the hands of successive governments over the past twenty years.

Gyenes said that health care in the country had been continually under-financed. He added that his association supported any political formation whose policies supported its aims, Jobbik being among them.

Vona said that people had "become mere tools in the hands of profiteering politicians."

He said that Jobbik would seek to identify any illegal transactions and legal remedy, adding that "the current, irresponsible and corrupt political elite see national health care as a clip-joint."

Vona said that Jobbik was considering forming co-operation agreements with professional associations and had already signed a co-operation agreement with the police trade union TMRSZ.

An official investigation, launched by Justice Minister Tibor Draskovics, examined the cooperation agreement between TMRSZ (Ready-to-Act Trade Union) and the radical nationalist Jobbik party and found the union's activities broke the law.
