In the predominantly Catholic countries of Italy and Croatia, the Catholic Church has been the main opponent to either the introduction of civil unions or marriage for same-sex-couples. In July 2013, 750,000 petition signatures were collected by the conservative group "In the Name of the Family", strongly supported by Catholic church leaders. This directly led to the 2013 referendum whereby the constitution was amended to state that marriage is only a union between a man and a woman. In February 2016 the Italian Prime Minister, Matteo Renzi, rejected the Catholic Church's interference in a parliamentary debate to introduce civil unions and adoption rights for same-sex partners. This followed Bagnasco's (Archbishop of Genoa) attempt to get the Italian Senate to carry out a secret ballot in the hope it would make it easier for lawmakers to follow their conscience, rather than the party line. Bagnasco had compared the idea of recognizing same-sex unions directly with state recognition for incest and pedophilia.
