The European Parliament plenary on March 25, 2026, witnessed a sharp divergence of views particularly between António Costa of the European Council and several Left-wing Members of the European Parliament (MEPs) concerning EU policies on Ukraine, the Middle East, and energy. Costa defended the EU’s firm backing for Ukraine, opposition to any member state blocking agreed support, and the One Europe, One Market agenda aimed at simplifying and strengthening the single market. In contrast, Left MEPs like Iratxe García Pérez, Özlem Demirel, and Isabel Serra Sánchez criticized the EU’s foreign policy stance, particularly condemning military actions in the Middle East, linking those to energy price hikes, and calling for cessation of cooperation with Israel. They also pushed for accelerated decarbonization coupled with social protection. This fundamental disagreement highlighted tensions between proponents of traditional EU unity and strategic autonomy versus critics emphasizing humanitarian concerns and the environmental-social nexus.
The debate took place in the European Parliament plenary, following the European Council meeting conclusions from March 19–20, 2026. It centered on multiple political fissures involving Ukraine’s support, energy relief mechanisms, migration, defense, and single market reforms.
Several contributors offered concrete proposals. António Costa’s agenda involved tangible targets for market simplification, such as advancing the voluntary 28th regime, completing the Savings and Investment Union, and combating internal barriers by 2027. Valdis Dombrovskis of the European Commission echoed these initiatives and proposed a competitiveness package with targets for burden reduction and ten omnibus deregulatory measures, alongside maintaining sanctions and financial backing for Ukraine including new sanctions on Russian energy revenues and banks.
On the energy front, cleavages emerged over the EU Emissions Trading System (ETS). Costa and Dombrovskis supported maintaining and modernizing the ETS with updated benchmarks and market stability reserves, aiming to reduce gas consumption. In opposition, figures like Patryk Jaki (ECR) and Carlo Fidanza (ECR) criticized the ETS for increasing costs and undermining industrial competitiveness, calling for suspension or adjustments to avoid penalizing energy consumers and sectors like fishers and farmers.
The debate also exposed contrasting visions on sovereignty vs. integration. Costa emphasized resisting national vetoes that block EU-sanctioned Ukraine support, directly confronting Hungary’s blockade and advocating for unity and ‘fair and sincere cooperation’ within unanimity rules. Conversely, some MEPs from Hungary’s affiliated groups defended national decision-making autonomy and criticized EU interference.
Stakeholders most affected by these debates include: EU producers, particularly in energy-intensive industries facing green regulation costs; consumers vulnerable to fluctuating energy prices and social inequalities; national authorities balancing energy security and migration control; and EU regulatory bodies managing sanctions, market reforms, and environmental targets.
Looking ahead, the institutions are likely to continue working on the One Europe, One Market agenda with an emphasis on simplification and competitiveness while maintaining political and financial support for Ukraine amid ongoing geopolitical tensions. The persistent disputes over energy policies and Middle East stances suggest ongoing challenges in reconciling EU’s strategic ambitions with internal diversity of views and competing national interests.
