The SDP is a communitarian, ‘red and blue’ centrist political party. We strongly advocate the ‘Social Market’ economic model and hold a pro nation-state, eurosceptic outlook.

We have a long and distinct political heritage, the party’s roots going back to 1981 when four prominent Labour Party figures issued the ‘Limehouse Declaration’, which led to the creation of the original SDP.

The party has been sustained by those truly committed to social democracy and its advancement. Support for the party has surged in recent years and we’re proud to have members throughout the UK who trace their SDP membership back to 1981.

The SDP aims to provide a political home to all social democrats who seek a stronger and more capable state along with greater individual responsibility, trust and social solidarity.
