The DUP says it has made a formal complaint against an academic who wrote an email claiming the party may have been responsible for gay and lesbian young people killing themselves.
Jim Wells said he had seen an email written by Dr Ellison to a woman who had given evidence for the Bill.
The email said: "Who knows how many gays and lesbian young people in Northern Ireland have committed suicide because of this bloody party".
