Sinn Féin MEP Martina Anderson has said homophobia must be tackled in all its forms.
Speaking before taking part in a panel discussion on Derry as part of the Foyle Pride celebrations, Ms Anderson said;
"The Foyle Pride festival is a fantastic occasion as it gives us the opportunity to stand in solidarity with the LBGTQ&I community and celebrate the contribution they make to our society.
"Thankfully attitudes are changing and society is becoming much more welcoming to the gay community.
"Difficulties still exist however and, unfortunately, homophobic attitudes remain in some quarters. These must be challenged.
"Sinn Féin has been to the forefront of supporting the LGBTQ&I community and have been driving the campaign for marriage equality.
"We have tabled motions in local Councils from Cork to Belfast and Dublin to Derry. And we again had SDLP, DUP and UUP councillors not supporting the motions.
"Sinn Féin is the only political party where all MLAs turned up and voted in favour of marriage equality in Stormont 2013.
"In Europe as a member of the LGBT Intergroup I have hosted delegations from the LGBTQ&I community in the North and challenged discrimination against the gay community across all member states.
"Sinn Féin will continue to stand up for the LGBTQ&I community and challenge homophobia and discrimination wherever it arises."
