In 1974, the new regime that ascended power on 25 April wound up the Lusitânia and nationalised the ANI, turning it into ANOP - Agência Noticiosa Portuguesa.

Due to financial difficulties and other problems with ANOP, the government decides to abolish it in 1982, and support the creation of another agency, this time in the private sector, the NP - Notícias de Portugal.

Although abolished in December 1986, a decree signed by Prime Minister Aníbal Cavaco Silva and promulgated by President Mario Soares, which determined the "closing by liquidation" of ANOP,  was published in the Official Gazette only in March 2014.
