BUDAPEST, Hungary — Outgoing Hungarian Prime Minister Viktor Orbán will not take his seat in parliament following a landslide election loss this month, and will instead focus on rebuilding his nationalist-populist political community, he announced Saturday in a video on social media.

Hungary's April 12 election brought an end to Orbán's 16 years in power when voters cast their ballots overwhelmingly for a center-right challenger who promised to crack down on endemic corruption and restore Hungary's democratic institutions that had been eroded under Orbán.
