As the full scale of his win in the European elections became apparent, a beaming Matteo Salvini sent out a photograph to his millions of supporters in Italy.

Standing in his office, he held a handwritten placard that read “First party in Italy – thank you”, a reference to the thumping win scored by the League, the hard-Right party he leads.

But it was the objects arrayed behind him on a bookshelf that sent an equally important, if less obvious message, not just to voters in Italy but to the rest of the world.

There was a baseball cap with the slogan Make America Great Again, a photograph of Vladimir Putin and behind it a book about the Russian president that bore his portrait.

On the shelf below was a gold-framed icon of Christ, his head surrounded by a halo.

The mise-en-scene put Mr Salvini squarely at the nexus of a populist movement that draws inspiration from Donald Trump, lauds Putin’s strong man style of governance and obsesses over threats to Europe’s Judeo-Christian roots.

The pugnacious Italian interior minister is the poster boy for a nationalist, populist movement that is now vowing to radically change the EU from within and to take on the mainstream parties that have dominated Brussels for decades.
