BRUSSELS — Brussels is making a final push to get the European Union’s long-awaited trade deal with the Latin American Mercosur bloc over the finish line this week.

The European Commission is expected to issue a declaration aimed at reassuring countries that have held out against the deal before a decisive vote on Friday, five officials with direct knowledge of the discussions told POLITICO. While the substance of the declaration is still unclear some of the officials, speaking on condition of anonymity, suggested they could include reassurances on payments to European farmers.

That would be critical for winning back the support of Italian Prime Minister Giorgia Meloni, who pulled the emergency brake before an EU leaders’ summit in Brussels last month under pressure from her country’s powerful farming lobby.

Under the EU’s voting rules, a so-called qualified majority — of 15 out of the bloc’s 27 member countries representing 65 percent of its population — would be needed to back the deal that has been in the works for a quarter century.

Italy, with its large population, effectively holds the casting vote. If the Commission can offer reassurances on some money for farmers under the EU’s next seven-year budget, which runs from 2028 to 2034, that would help soften the impact of a proposed one-fifth reduction in the Common Agricultural Policy, under which the bloc distributes subsidies to farmers.

The new concessions may not win over France and Poland, the main opponents of the accord with Mercosur — which groups Argentina, Brazil, Paraguay and Uruguay. But, without Italy, they and their allies would lack the votes to block the deal on Friday.

The agriculture ministers of France and Poland are expected to visit Brussels Wednesday to seek reassurances that supplementary safeguards agreed on by the EU institutions to prevent European farmers from being undercut by a possible glut of South American produce are strong enough.

If the vote goes through, Commission President Ursula von der Leyen would finally be free to fly to Paraguay as early as next week to sign the deal, which has been under negotiation for over a quarter of a century and would create a free-trade area of more than 700 million people and abolish duties on 90 percent of EU exports.

POLITICO has reached out to the European Commission for comment. Earlier on Monday, chief spokesperson Paula Pinho said: “We are on the right track to envisage a signing of the agreement and we do hope that will take place quite soon.”

The Italian government did not immediately respond to a request for comment.
