Al-Qaeda in the Islamic Maghreb (#AQIM) has confirmed the death of its Algerian leader Abdelmalek Droukdel (aka Abu Musab Abd al-Wadud) in a French operation in northern Mali, without naming a successor. France had announced his death on 5 Jun saying he died on 3 June.
The audio message was delivered by AQIM's media chief Abu Abd al-Ilah Ahmad who delivered four messages but gave no info about who may succeed Droukdel. AQIM senior figure Abu Ubaydah Yusuf al-Annabi in my opinion is a strong contender.
The AQIM media chief offered condolences to jihadists in Mali, Niger, Burkina Faso, Tunisia and Algeria on the death of "your emir". This highlights the broader/overarching role played by the AQIM leader with regard to jihadists in the Sahel (#JNIM) and not just in North Africa.
In many cases jihadist groups (both IS and al-Qaeda) announce the successor when they confirm the death of a leader (AQAP in Feb 2019 & Jun 2015; IS in Oct 2019), but that is not always the case (eg AQ 2011 confirmed death of UBL and a week later announced Zawahiri as successor)
