On Friday, Alabama inmate Kenneth Smith is likely to become the first person to be executed by nitrogen gas. We hear from the pastor who'll accompany him in the death chamber.

Also in the programme: the lawyer for Austrian sex offender Josef Fritzl, who is to be moved from a high-security to a regular jail, tells us that it is time for mercy; and we speak to the daughter of Mohammed Yunus, the Bangladeshi Nobel laureate who is facing six months in prison.
