They discuss the importance of inclusivity for global tax changes, the difficulties of Pillar One, the challenges by implementing Pillar Two and the advantages of multilateralism. Finally Pascal shares some insights regarding his new position as a Partner at the Brunswick Group, a UK based communication firm, where he gives advice to companies on strategic and critical issues, like tax, ESG, geopolitical issues and much more.
