Mr Mutharika, speaking as UN chief Ban Ki-moon visited Lilongwe, said he had ordered their immediate release. Steven Monjeza, 26, and Tiwonge Chimbalanga, 20, were given 14-year jail terms after being convicted of gross indecency and unnatural acts. The case has sparked international condemnation and a debate about homosexuality in the country. Mr Ban said he welcomed the president's decision. Correspondents say Malawi is a deeply conservative society where religious leaders equate same-sex liaisons with Satanism. Mr Mutharika, who has in the past dismissed homosexuality as alien, said he had set them free on humanitarian grounds. "These boys committed a crime against our culture, our religion and our laws," he said after meeting Mr Ban. "However, as the head of state I hereby pardon them and therefore ask for their immediate release with no conditions."
