Thousands of Irish farmers protested on Saturday against the European Union’s trade deal with the South American bloc Mercosur, a day after EU states approved the treaty despite opposition from Ireland and France.

Tractors streamed into the roads of Athlone, in central Ireland, for the demonstration, displaying signs including “Stop EU-Mercosur” and ones with the European Union flag emblazoned with the words “sell out”.

Farmers on Friday also marched in Poland and blocked roads in France and Belgium as the EU gave the green light to the trade deal, which has been welcomed by business groups but heavily criticised by European farmers.

The accord, more than 25 years in the making, would create one of the world’s largest free-trade areas, boosting commerce between the 27-nation EU and the Mercosur bloc comprising Brazil, Paraguay, Argentina and Uruguay.

Major Mercosur exports to the EU include agricultural products and minerals, while the EU would export machinery, chemicals and pharmaceuticals with lowered tariffs applied.

But many European farmers fear their livelihoods will be undercut by a flow of cheaper goods from agricultural giant Brazil and its neighbours, prompting Ireland, France, Poland, Hungary and Austria to vote against the accord.

The agreement is widely opposed by Irish farmers for fear it will result in an influx of an extra 99,000 tonnes of cheap beef from South America, disrupting Irish agriculture.
