The government also changed the ban on blood donations from men who have had sexual relations with other men from a permanent ban to a one-year ban, though the permanent ban remains in Northern Ireland. When David Cameron announced his resignation on 13 July 2016, the former Prime Minister said in his speech, "enabling those who love each other to get married whatever their sexuality" was one of his most significant accomplishments.
