The Social Democratic Party of Transnistria was a social-democratic political party in Transnistria.
It was formed on 25 January 2007 by Aleksandr Radchenko, a former member of the Transnistrian Supreme Council. Unlike other political parties in Transnistria, it supports conditional reintegration into Moldova with a high amount of autonomy for Transnistria.[1] After 2009, the party lost its influence and faded from relevancy., it has no offices, staff nor membership, although it never officially declared its dissolution.
