Gay blood donation: 'No evidence' to support outright ban

Northern Ireland's Department of Health does not have any medical evidence of its own to support a permanent ban on gay men donating blood, a BBC investigation has found.

Other parts of the UK have a one-year deferral period for men who have had sex with men and want to donate, but Northern Ireland has an outright ban.

First Minister Peter Robinson MLA said the only issue for people was the quality of blood.
