“The newly published asset declarations have shown the entire country that Tisza Party representatives are wealthy,” Orban said.

“They have also taken the lead in luxury lifestyles. Gifted BMWs are flying around, ministers are being driven in Maseratis, while our representatives can only look on,” he added.

Orban also condemned what he described as politically motivated investigations into his former administration, arguing that the government's actions amounted to an abuse of power.

“The current showcase investigations, politically motivated proceedings, aggressiveness and abuse of power will ultimately work in our favour,” he said. “The government is gradually entering into an abusive relationship with the entire country.”

His remarks came after Hungary's Integrity Authority said senior officials from the Orban era could potentially face prosecution over an estimated €3.5 billion in missing EU funds . While neither Orban nor members of his inner circle have been directly accused, parliament has established five commissions to investigate alleged corruption under his administration.

Despite attacking the government, Orban acknowledged that Fidesz had contributed to its own defeat in April's election . “Our election message did not work, while our opponents' message proved far more attractive,” he said.

Delegates overwhelmingly voted to keep Orban as Fidesz leader, backing him by 729 votes to eight.

The former prime minister's re-election comes as Fidesz seeks to rebuild after losing power to Peter Magyar's Tisza Party, which secured a two-thirds parliamentary majority in April.

He also criticised the handling of Hungary's dispute with the European Union over asylum policy, arguing that the previous government had knowingly exposed the country to substantial financial penalties.

“This daily one million euros, about which the cabinet meeting minutes acknowledge, not that it is justified, but that the previous government did everything to ensure there would be a penalty of this severity,” Magyar said.

In June 2024, the European Court of Justice fined Hungary €200 million and imposed an additional €1 million daily penalty for failing to comply with EU asylum regulations.

Magyar said his government was exploring solutions used elsewhere in Europe to meet EU requirements while avoiding the establishment of migrant camps in Hungary.

“We are working to develop such a regulation so that, on the one hand, there indeed won't be migrant camps in Hungary, and we won't have to continue paying this daily fine of one million euros,” he said.

Asked about the EU Migration and Asylum Pact, which entered into force on Friday, Magyar said Hungary would favour providing technical assistance to other member states rather than accepting relocated asylum seekers.

“There is a third option, for example, which the Orban government also used previously, providing additional technical border protection assistance through Frontex to either Greece or Serbia,” he said.

Magyar argued that the pact includes broader provisions beyond migrant relocation and introduces stricter migration rules than previous EU frameworks.
