Asia Bibi - a Pakistani Christian who was held for eight years under a death sentence for supposed blasphemy - has said her "whole life suffered".
Ms Bibi was convicted in her home country in 2010 accused of insulting the prophet Mohammed after she drank from the same well as Muslim co-workers.
Peers and MPs put pressure on the UK Government to offer asylum to Ms Bibi, who currently lives in Canada after Ottawa offered sanctuary.
Ms Bibi, whose conviction was reversed by the Pakistani supreme court, urged the "whole world" to act on blasphemy laws.
Speaking to the Sunday Telegraph, she said: "The way any person is alleged of blasphemy without any proper investigation, without any proper proof, that should be noticed.
"This blasphemy law should be reviewed and there should be proper investigation mechanisms while applying this law." She added: "My whole life suffered, my children suffered and this had a huge impact on my life."
Mrs Bibi thanked the supreme court for acquitting her, but said that others also needed fair trials.
