Is Hungary's Victor Orban popular or a populist?

The election campaign in Hungary has been dominated by one issue, immigration.

Right-wing Prime Minister Viktor Orban's hardline approach to migrants has grown stronger over the years.

In 2015, more than 400,000 refugees - many fleeing the Syrian war - passed through the country.

In response, Hungary built a fence along its border with Serbia and Croatia, to keep them out.

Orban has vowed to continue fighting against the EU quota on refugees, a plan meant to relocate asylum seekers across Europe.

Analysts say his policies could have a long-lasting impact on the European Union. Far-right and populist parties have made gains in other elections including in Italy and Austria. It is suggested a strong win for Orban could trigger cracks in the EU.
