This is an entry from: LIVE: Erdogan says Turkey has evidence Khashoggi murder was premeditated
What does Erdogan hope to do with his speech?
23 October 2018 09:48 BST
Turkey has been drip-feeding information from its Khashoggi investigation for the past three weeks, but has yet to officially declare anything on the record or present evidence so far, writes our correspondent Ece Goksedef from Istanbul.
The purpose of the leaks to both local and international media has been to attract global attention and pressure the Saudis - who eventually admitted they had killed Khashoggi last Friday.
Yet Turkey has continued to leak evidence following Saudi's admission. The perception in Turkey is that the president and authorities are not happy with Saudi's explanation of the events.
Now Erdogan will use his speech as a warning to Saudi and the US to be more transparent about what happened.
