Morocco hosted an important summit with the presence of up to 40 former heads of government and former Foreign Ministers from various African countries, among them some twenty signatories of the so-called "Tangiers Call" group, who advocated the expulsion of the self-styled Sahrawi Arab Democratic Republic (SADR) from the framework of the African Union (AU) in a bid for regional stability and the defence of the territorial integrity of the Moroccan kingdom, which continues to defend the belonging of Western Sahara to the national territory against the position of the Polisario Front, linked to the SADR, which continues to demand the holding of a referendum on independence among the Sahrawi people.
