The presidency, however, has seemingly lost its political import. Parliament has effectively ruled Peru for the last decade: it has impeached four presidents since 2020 and rewritten the constitution to introduce a powerful new Senate, set to begin functioning on July 28. This Senate is, in essence, constitutionally anti-constitutional – its powers systematically undermine the very checks and balances that liberal constitutionalism exists to protect.
