BUDAPEST, May 24 (Reuters) - Hungarian opposition leader Peter Magyar walked across the border to Romania on Saturday after a week-long journey, in a attempt to win support of the ethnic Hungarians in Romania and appeal to conservative voters in the run-up to the 2026 elections.

Magyar's centre-right Tisza party emerged last year to mount the most serious challenge to nationalist Prime Minister Viktor Orban since he rose to power in 2010.
