Westland New Post (WNP) was a Belgian extreme right-wing organization founded in March 1981 by Paul Latinus and members of the Front de la Jeunesse (FJ). The Front de la Jeunesse was in 1983 convicted for being a private militia.
WNP disappeared in 1984: its leader Paul Latinus was found dead in his girlfriend's home in April of that year, and the other members came into conflict.
Marcel Barbier, a WNP member, was convicted in May 1987 for a gruesome double murder at a synagogue on the la rue de la Pastorale in Anderlecht on February 18, 1982. One of the victims, Alphonse Vandermeulen, had been married to Barbier's current girlfriend, Marcelle Gobert. The police interrogated Barbier and his girlfriend, and searched both their homes, but no arrests were made. The police investigation into the murders was without success until August 16, 1983, when a violent incident occurred at Barbier's home in Saint-Gilles. Barbier was arrested, and when the police searched his home they found confidential NATO material, various weapons and neo-Nazi material. It also turned out that Barbier was a former member of the Front de la Jeunesse, and was currently a member of a neo-Nazi organization called Chevalerie teutonique. Barbier was convicted and jailed for this violent incident, but the investigation into the Pastorale murders continued.
During the interrogation of Barbier, the police found out about Westland New Post, although it was later revealed this organization was already known to the Belgian State Security Service, with an agent (albeit on his own initiative) already infiltrating the organization at the end of 1981, but the intelligence service did not communicate what it knew to the police or judiciary services. The police then investigated the WNP members to find out whether it was a private militia. Paul Latinus told the police that Barbier and another WNP member were behind the murders. Latinus had helped Barbier getting rid of the murder weapon and other relevant evidence. Barbier was the only person convicted for this murder, although other WNP members were suspect.
During the investigation of the incident at Barbier's home, the police found confidential NATO documents. Barbier told the police they were not his, but the possession of another WNP member, Michel Libert. Michel Libert worked as a military volunteer at the NATO Transmission Centre in Evere. Latinus, leader of WNP, was interrogated multiple times by the police and would confess to the stealing of confidential NATO documents. Security at the Centre was not high, and Libert delivered the documents to Latinus, who later published some of the material in the two editions of the WNP Althing magazine, which was delivered among others to military personnel. Latinus told the police that this was on behalf of his 'American superiors', to wake up the military command at NATO that leaks were happening, with only material on the Soviet Union being published in the Althing. Later it turned out more WNP members worked at the NATO Transmission Centre, and would deliver material, via Libert, to Latinus.
