• Hungary elections: what is at stake and who is likely to win?

Viktor Orban and his centre-right rival, Peter Magyar, have traded accusations of enlisting foreign interference in a high-stakes election that polls suggest could mark the end of the nationalist Hungarian prime minister's 16 years in power.

As the two leaders' campaigns entered their final stages before this weekend's vote, which is being watched as keenly in Brussels, Moscow and Washington as in Budapest, Orban said on social media on Friday that his opponent would stop at nothing to seize power".
