US Vice-President JD Vance has insisted he was right to stage a two-day campaign visit to back Hungarian Prime Minister Viktor Orbán five days before he was voted out of office by opposition party Tisza's landslide victory. Insisting Orbán was a 'great guy' who did a 'very good job', Vance told Fox News he was 'one of the few European leaders we've seen who's been willing to stand up to the bureaucracy in Brussels'. While he was sad Orbán had lost, he was sure the US would 'work very well' with the new government, he said. Péter Magyar, who led Tisza to victory, had been critical of Vance's intervention, warning last week that 'no foreign country may interfere in Hungarian elections'. However, he said on Monday the US was a 'strong and important' Nato partner and would communicate with President Donald Trump or others when necessary. Orbán will continue to run Hungary in a caretaker role until Magyar is sworn in, and the three party leaders with seats in parliament have been invited to meet President Tamás Sulyok on Wednesday. Sulyok has the task of convening Hungary's new parliament and recommending the next prime minister by 12 May, and Magyar has urged him to do that as soon as possible and then resign. Magyar has suggested he could become prime minister on 5 May or even sooner, emphasizing the need for a swift transition and addressing pressing issues such as unlocking EU funding and tackling corruption in Hungary.
