Racist or just brutal realism? Hungary’s been condemned for building a new Iron Curtain to keep out migrants. But its PM says he’s done it to avoid multicultural Britain’s mistakes… and his popularity is soaring

From the back garden of Istvan Molnar’s home, you can see Hungary’s newly erected ‘Iron Curtain’ in the distance.

The razor-wire fence has become a defining symbol of the migrant crisis. The barricade — 4m high and constructed in six weeks on the back of prison labour — runs the length of the country’s 110-mile border with Serbia.

The Berlin Wall, by comparison, was 96 miles long. This hinterland between Hungary and the Balkans was once the main entry point to the European Union for the diaspora pouring out of the Middle East.
