His European tour centered on last weekend's Italian election, which Bannon called "an earthquake" after populist and anti-immigration parties outperformed traditional parties.
Bannon, who served as US President Trump's strategist for seven months before the relationship deteriorated, crossed the Atlantic to embark upon a tour of Europe's right-wing parties.
Bannon was himself a high-profile departure from the White House last August and was written off by Trump earlier this year, who named him "sloppy Steve", following the publication in January of incendiary comments attributed to him.

The speech will be the second in Europe for Mr Bannon who recently spoke to a sold-out arena in Zurich, Switzerland where he spoke on the subject of on populism of the left and the right. It won more seats in the European Parliament than any other French party in 2014. She bowed out of politics after her aunt's presidential defeat, but is expected to come back in a new role.
"Since last Sunday, there really is the impression that the victory of the League gave new confidence, new hope to Marine Le Pen and other leaders who see a favorable historic tendency", Camus said, citing Britain's Brexit vote and Donald Trump's presidential victory in the U.S. as similar guideposts.
