The Vatican Summit, held in collaboration with the Independent Commission for the Reform of International Corporate Taxation (ICRICT) which PSI co-chairs, highlighted the vital role of trade unions in the movement for international tax reform.

PSI General Secretary Daniel Bertossa spoke at the summit alongside Brazilian President Luiz Inácio Lula da Silva, Spanish President Pedro Sánchez, Economist Jayati Ghosh and Nobel laureate Joseph E. Stiglitz.

Bertossa said: "When the rich refuse to pay tax, Their wealth is deployed to tip the scales away from working people. That’s why PSI & the 200 million people of the global labour movement are committed to tax justice."

The summit (watch the video recording here) builds on recent tax victories which PSI unions have helped secure around the world including

• G20/OECD's landmark minimum global corporate tax

• Australia's groundbreaking corporate tax transparency law

• approval of UN Tax Convention talks, underway currently

• the launch of the "Tax the Super-Rich Alliance"
