From reforming the U.N. Security Council to taxing billionaires, thousands of leftists gathered in Barcelona over the weekend to brainstorm ways to halt the rise of authoritarianism and win back voters who have drifted rightward.

The gathering, which drew more than 6,000 people from over 40 countries, comes as far-right and nationalist forces have gained ground globally, eclipsing the left with messaging that pins cost-of-living concerns on immigration, outdated institutions and out-of-touch political elites.

Spearheaded by Spain¡¯s Socialist Prime Minister Pedro Sanchez, whose outspoken opposition to U.S. President Trump¡¯s foreign policy has ?boosted his image, the summit was buoyed by hopes that the far-right surge may have peaked, with Trump¡¯s polling numbers falling, Hungary¡¯s Victor Orban ousted after 16 years ?in government ?and the French far right underperforming in last month¡¯s municipal elections.
