I am glad to see a columnist in Cumhuriyet newspaper, virtually the CHP's house journal, arguing that it is vital for the HDP to be brought into the new process:

Apparently, Kılıçdaroğlu also stressed at the meeting that the absence of the HDP was a mistake, provoking a non-committal response from Erdoğan.
