Socialist Party of the Oppressed (tr|Ezilenlerin Sosyalist Partisi, ESP; ku|Partiya Sosyalîst a Bindestan, PSB)[3] is a Marxist-Leninist political party in the Republic of Turkey. It defines itself as "a militant revolutionary socialist party fighting for a workers'-labourers' federative republic in Turkey and Northern Kurdistan."[4]
Some sources, including the public officials, hold the view that ESP is a legal front for the banned ICOR affiliate Marxist–Leninist Communist Party.[5] [6] [7] Among its founders is Figen Yüksekdağ, the former co-president of the Peoples' Democratic Party.
The party is one of the participants in the Peoples' Democratic Congress, a political initiative instrumental in founding the Peoples' Democratic Party in 2012.[8]
In 2013 The Daily Telegraph called it "a small leftist group" after the homes of 90 ESP members were raided in connection with their involvement in the 2013 protests in Turkey.[9] The Telegraph noted that "Police also searched the offices of the Atilim daily [''[[Atılım]]] and the Etkin news agency, local media outlets linked to the ESP group, the NTV and CNN-Turk television stations reported."[9] [10] [11]
The youth wing of the Socialist Party of the Oppressed, known as the Socialist Youth Associations Federation (SGDF),[12] was the main target of the 2015 Suruç bombing.[13] A group had travelled from Istanbul to Suruç on the Syrian border to assist in the reconstruction of the neighboring Syrian town of Kobanî after it was destroyed by warfare.[12]
