Mainstream conservative lawmakers and politicians from Europe are planning to attend President-elect Donald J. Trump’s inauguration. But the European contingent is also expected to include leaders of some parties that are on the right-wing fringes in their own countries or have only recently begun to gain greater acceptance at home.
Many of the European politicians who have flocked to Washington share Mr. Trump’s anti-immigrant fervor.
Headlining the European attendees is Prime Minister Giorgia Meloni of Italy, according to her official agenda. Ms. Meloni, a conservative, was one of the first leaders to visit Mr. Trump at Mar-a-Lago after his election, on Jan. 4.
Ms. Meloni, who is trying to stop the flows of migrants to her country, is considered one of Europe’s strongest leaders, and her supporters hope that she will emerge as a privileged ally of Mr. Trump in Europe.
The most notable absence is Prime Minister Viktor Orban of Hungary, one of Mr. Trump’s most fervent fans in Europe. Despite being widely admired by many American conservatives as an ideological beacon and praised by Mr. Trump as “fantastic,” Hungary’s proudly illiberal leader was not invited to attend, according to a Facebook post by Zoltan Kovacs, Hungary’s secretary of state for international communications.
“To be crystal clear: Viktor Orbán will not participate in the event. President Trump’s team — in accordance with tradition — did not invite any foreign heads of state or government,” Mr. Kovacs said.
