The HDP is a left-wing political party, associated with the Kurds, actively defending the rights of all ethnic minorities in Turkey. The HDP has maintained ties with the Kurdistan Workers' Party (PKK), a group labeled by Erdogan and several other institutions as a terrorist organization. In June, the HDP became the first Kurdish-associated political party to reach the 10 percent threshold for representation in parliament.
