BRUSSELS — The French government called on Sunday to postpone a crucial vote by countries on the EU-Mercosur trade agreement, widening a rift within the bloc over the controversial pact.

“France is asking for the December deadlines to be pushed back so we can keep working and get the legitimate protections our European agriculture needs,” the office of Prime Minister Sébastien Lecornu said Sunday evening.

The statement confirmed a POLITICO report on Thursday that Paris was pushing for a delay. It comes within sight of the finish line for the European Union to finally close the agreement with Argentina, Brazil, Uruguay and Paraguay that has been in negotiations for over 25 years and would create a common market of over 700 million people.

Denmark, which holds the presidency of the Council of the EU, has vowed to hold the vote in time for European Commission President Ursula von der Leyen to fly to Brazil on Dec. 20 to sign the deal.

Several countries warn that the holdup risks ultimately killing the trade deal, concerned that further stalling it could embolden opposition in the European Parliament or complicate next steps when Paraguay, which is skeptical toward the agreement, takes over the presidency of the Mercosur bloc from current holder Brazil.

Pro-deal countries, including Germany, Sweden and Spain, argue that France’s concerns have already been accommodated, pointing to proposed additional safeguards designed to protect European farmers in the event of a surge in Latin American beef or poultry imports.

But with those safeguards still not finalized, France says it still can’t back the deal, wary that it could enrage the country’s politically powerful farming community.

Brussels also announced this month it was planning to strengthen its border controls on food, animal and plant imports.

“These advances are still incomplete and must be finalized and implemented in an operational, robust and effective manner in order to produce and appreciate their full effects,” Lecornu’s office said.

Despite Denmark’s resolve to hold the vote in time, final talks among EU member countries may not be wrapped up before a summit of European leaders on Thursday and Friday this week. A big farmers’ protest is planned in Brussels on Thursday.

The Commission declined to comment.
