The Social Democratic and Labour Party was founded in 1970 as an anti-sectarian political movement with the aim of reconciling the people of the island in a new, just and prosperous Ireland.
Today, that mission matters more than ever.
We believe this isn't as good as it gets. Too many people here are still held back by division, inequality and lack of opportunity.
The SDLP has a plan for a better future: to build something new, grounded in our progressive, centre-left and anti-sectarian values. A politics that acts today to work towards a better future. That delivers on its promises. That prioritises delivery over party politics and makes a real difference in people's lives.
That's why we are working every day - at Westminster, in the Assembly as the Official Opposition, and in councils across the North - calling for delivery, holding those in power to account, and standing up for communities who have been let down for so long.
We believe a New Ireland offers the best opportunity to deliver better outcomes for all - north and south, from every background. But we also know that building a better Northern Ireland now is essential to winning that future and bringing people with us.
Our central mission remains clear: to builder a better future that brings people together - across communities, backgrounds and traditions - in a new, inclusive Ireland.
If you believe in that future Join Us
We are also proud members of the Party of European Socialists and subscribe to the PES declaration of principles.
