Swiss Parliament's Lower House Votes Down Mercosur Trade Deal Over Concerns

Swiss Lawmakers Reject Mercosur Agreement

ZURICH, June 18 (Reuters) - Switzerland's lower house of parliament has rejected an agreement with the South American trade bloc Mercosur amid opposition from both the right and left of the political spectrum.

Next Steps for the Mercosur Deal

The deal now moves to the upper chamber of parliament and could return to the lower house if approved there.

Details of the Parliamentary Vote

Lawmakers late on Wednesday voted down the accord struck last year by a margin of 96 to 86, with nine abstentions.

Opposition from Multiple Political Sides

Resistance to the agreement came both from conservative lawmakers representing farmers' interests and from parties on the left that raised concerns encompassing issues such as labour practices and the destruction of the rain forest.

Key Takeaways

  • The agreement, signed in September 2025 after eight years of negotiations, would grant tariff-free access for about 96% of Swiss exports to the Mercosur bloc after transition periods, potentially saving CHF 155 million annually. (seco.admin.ch)
  • Opposition came from farmers demanding CHF 880 million in compensation and left-wing parties citing insufficient safeguards on labour rights, deforestation risk, and environmental protection. (swissinfo.ch)
  • Environmental groups warn that agricultural trade under the deal could more than double CO₂ emissions in that sector, posing risks to Switzerland’s climate commitments unless accompanied by stronger mitigation measures. (publiceye.ch)
