From 5 a.m. on Monday, April 27, 2026, burning pallets, tires, human chains, and union banners blocked the entrances of about fifty French penal establishments. At the call of UFAP-UNSa Justice, the leading guards' union, the movement aims to denounce a situation described as "out of control": historic overcrowding, staff shortages, repeated assaults on personnel, and an increasingly shared sense of political abandonment. According to the union's count, communicated to AFP mid-morning, "22% of establishments are blocked," making it the largest movement since the historic strike of 2018. The Ministry of Justice, headed by Gérald Darmanin, is to meet with union organizations on Tuesday, April 28.

Overcrowding Becomes Unbearable

The figures speak for themselves. As of April 1, 2026, according to official statistics from the Directorate of Penitentiary Administration, France had 81,412 inmates for 62,612 operational places, resulting in an average prison density of 130% and peaks of over 200% in certain establishments (Bordeaux-Gradignan, Nîmes, La Réunion). More than 4,600 people are sleeping on mattresses on the floor—a level never reached under the Fifth Republic. France has been repeatedly condemned by the European Court of Human Rights for undignified detention conditions, and the General Inspector of Places of Deprivation of Liberty, Dominique Simonnot, published a damning report in March.

Hauts-de-France, Île-de-France, Sud-Est: Three Epicenters

The blockage map published by the union on Monday outlines three epicenters. In Hauts-de-France, 14 out of the region's 17 establishments were affected by mid-morning—notably the detention centers of Vendin-le-Vieil, Annœullin, Sequedin, Bapaume, and Maubeuge. In Île-de-France, blockades at the remand centers of Bois-d'Arcy (Yvelines), Fleury-Mérogis (Essonne, Europe's largest prison with 4,000 inmates for 2,855 places), and Fresnes (Val-de-Marne) caused delays in about a hundred judicial extractions. In the Southeast, the detention centers of Marseille, Aix-Luynes, and Avignon-Le Pontet are also blocked. At Bois-d'Arcy, AFP photographed guards displaying signs saying "the prison is burning, they are looking elsewhere."

Three Serious Assaults in Fifteen Days

The movement was triggered by three serious assaults on personnel that occurred since mid-April: at Vendin-le-Vieil, where a guard was stabbed by an inmate from the isolation wing on April 11; at Fleury-Mérogis, where another officer was beaten by three inmates on April 18; and at Réau, where an internal drug and mobile phone trafficking ring led to the indictment of two guards. UFAP-UNSa, through its general secretary Wilfried Fonck, denounces the ministry's "denial of reality" and demands three emergency measures: an immediate plan to recruit 3,000 additional guards, a salary increase, and a binding prison regulation mechanism (early release for short sentences nearing completion).

Darmanin Promises "Strong Announcements"

The Minister of Justice Gérald Darmanin, whose portfolio was expanded to include Justice since Sébastien Lecornu's arrival as Prime Minister in September 2025, reacted Monday early afternoon with a laconic statement: "I hear the suffering of the staff." He confirmed a meeting on Tuesday, April 28, at the Ministry of Justice with the three representative union organizations (UFAP-UNSa, FO Justice, CGT-Pénitentiaire), and promised "strong announcements" in the coming days. Behind the scenes, the minister's cabinet is working on a two-pronged plan: short-term (salary adjustments for guards, deployment of mobile intervention units) and medium-term (goal of 18,000 net additional places by 2030, compared to 15,000 in the Belloubet plan). However, the budget issue—delicate in the context of the austerity measures in the 2026 Finance Bill—remains the blind spot of the issue.

Unprecedented Political Mobilization

The movement extends far beyond just the union framework. Several local elected officials, from both the right and the left, have expressed their support for the guards. The president of Les Républicains, Laurent Wauquiez, demanded "an emergency prison plan." On the left, Socialist MEP Aurore Lalucq recalled that France had "the second highest prison density in Western Europe, behind Belgium." At the Rassemblement National, Jordan Bardella focused on the expulsion of undocumented foreign inmates, who, according to the ministry, represent 24% of the prison population. In the European Parliament, which convenes this week in Strasbourg for its April plenary session (April 27 to 30), a debate on detention conditions in Europe is scheduled for Wednesday.

Editorial Opinion

The blockage of French prisons on April 27 is not just another social movement. It is the culmination of systemic degradation, documented for twenty years by successive inspectors general and the European Court of Human Rights, and which all governments have postponed. The average density of 130%, the 4,600 mattresses on the floor, and the assaults on personnel are simply becoming unbearable—for inmates as well as for guards. Three avenues exist and are known: binding prison regulation (automatic release at the end of a sentence to reduce congestion), a massive construction plan (but with five to seven-year lead times), and a revised penal policy for short sentences (under 12 months). None of these choices are politically easy, which is why none have been decided upon in three five-year terms. Gérald Darmanin has two options: a courageous reform that assumes a break, or a new budgetary appeasement plan that will, once again, postpone the issue. The penitentiary street, however, no longer seems willing to wait.
