In July 1960, two months following the formation of the PRM, Miské was expelled along with several other youth leaders and Arab nationalists for their vocal opposition to and criticism of Daddah.
[2] Nahda advocated immediate independence from France and Mauritanian withdrawal from the French community, and also argued for closer relations with Morocco.
In response President Daddah arrested five leading members of Nahda, including Miské, and he was imprisoned in the remote Hodh Ech Chargui Region from May 1960 to February 1961.
Miske served in these roles from 1964 to 1966, and upon being recalled back to Mauritania was arrested on corruption charges, although he was found not guilty and was released a month later.
Miske then went into exile for twelve years, spending his time mostly in Paris, and founded the magazine Africasia.
