King Mohammed VI is said to be mulling an abdication. This rumor is in response to his reluctance to leave Europe and actually govern his country. Both of those links come from the same Spanish reporter, Pedro Canales, so they shouldn't be trusted entirely, but it's interesting to ponder consider whether Mohammed VI's abdication would be good or bad for Western Sahara.
The king would probably be replaced by Moulay Rachid, his brother who is said to be wavering on supporting the king. Rachid would hold the country in regency until the king's son came of age. What are Moulay's opinions about Western Sahara?
I'm not sure if an abdication would improve Western Sahara's chances for self-determination. Mohammed VI has treated Sahrawis nearly as brutally as his father did, but the power vacuum resulting from his abdication might encourage nervous army officers and politicians to react harshly to perceived Sahrawi threats.
