Thousands of Irish farmers staged nationwide protests on Thursday against the European Union’s trade agreement with the South American Mercosur bloc, a day after a majority of EU member states gave provisional approval to the long delayed deal.

Demonstrators drove tractors onto major roads and highways, blocking traffic in the central town of Athlone as farmers converged from across the country. Protesters carried placards reading “Stop EU–Mercosur” and chanted slogans accusing EU leaders of betraying farmers and undermining local agriculture.

Farmer groups argue the agreement would expose European producers to cheaper agricultural imports from Mercosur countries Brazil, Argentina, Uruguay and Paraguay which they say operate under lower environmental, labour and animal welfare standards. They warn this could drive down prices, threaten livelihoods, and weaken food security across Europe.

Under the terms of the deal, Mercosur would gain increased access to the EU market for agricultural products and raw materials, while European companies would benefit from reduced tariffs on exports such as machinery, chemicals and pharmaceuticals. EU officials say the agreement would strengthen economic ties and create new export opportunities, but critics say farmers will bear the brunt of the costs.

Irish farming organisations have called on the government to oppose the deal in its final stages, warning that protests could escalate if their concerns are ignored. Similar demonstrations have taken place in recent months in France, Belgium and other EU states, highlighting deep divisions over trade, agriculture and rural livelihoods.

The European Commission says safeguards will be included to protect sensitive sectors, but opponents argue the measures fall short and fail to address long-term risks to European farming.
