President Perón was ultimately deposed in a violent 1955 military coup. Bramuglia communicated with the first dictator installed after the coup, General Eduardo Lonardi, and offered to cooperate with the latter's policy of avoiding "victors or vanquished." Lonardi agreed, and actively considered naming him to the post of Labor Minister that had been denied him a decade earlier. The move backfired, however, when Lonardi was removed from office for his conciliatory stance in November. Bramuglia was briefly arrested, though his friendship with numerous policemen, as well as with the new War Minister, General León Bengoa, would protect him against further arrests, as well as against numerous death threats subsequently. He nonetheless established the Unión Popular (UP) in December as an attempt to develop a political alternative to the banned Peronist movement. He obtained permission from Lonardi's successor, General Pedro Aramburu, and was, in turn, publicly condemned by the exiled Perón.
