Every month, for 15 days, hundreds of women queue outside a public bank in the town square of Viçosa do Ceará, in rural northeast Brazil. As they wait to receive money from the Bolsa Familia programme – government aid for poor Brazilian families – a woman in her sixties speaks to them through a megaphone.

Liliane de Carvalho is there every single day from 6.30am, unless ‘something unexpected happens’. As a longstanding member of a local Catholic church, she’s preaching – but not about sin or guilt. She’s preaching about the right to abortion.
