The move would overturn a law dating back to 1865. San Marino is one of the last places in Europe where abortion is completely banned.
The Sammarinese Christian Democratic Party, which has strong ties to the Catholic Church and has governed the country for nearly 20 years, opposed the legalisation.
On the other hand, Francesca Nicolini, a doctor with the San Marino Women’s Union, said: “It’s unacceptable to view as criminals women who are forced to have abortions,”
Abortions have been legal in neighbouring Italy since 1978.
