Tens of thousands of Hungarians protested against the country's leadership on Saturday in one of the biggest demonstrations in years, organised by a former government insider who has shaken up Hungary's political landscape.

Peter Magyar, a lawyer and former diplomat who used to belong to an elite circle around Hungary's ruling party, publicly broke with the government in February and is now aiming to challenge the position of Viktor Orban, the powerful prime minister.
