Gambian President Adama Barrow’s newly appointed vice president, Fatoumata Tambajang, is a former United Nations Development Program staffer who was instrumental in uniting Gambia’s opposition parties against Jammeh.

Tambajang became a controversial figure after telling “The Guardian” newspaper late last year that Jammeh, who took power in a coup 22 years ago, would be prosecuted for crimes committed by his regime. Shortly after her comments were published Jammeh backtracked on conceding his December 1 election defeat, triggering a political crisis.

She also argued for a national commission for asset recovery to recover land and goods Jammeh allegedly seized for his own gain.

Tambajang was the first cabinet member to be announced by the newly-inaugurated Barrow, who is still in neighboring Senegal amid fears for his safety.

Government spokesman Halifa Sallah said the rest of Barrow’s government would be unveiled on Tuesday.

Ex-leader Jammeh dissolved the government, half of whom had already resigned, during a political crisis in which he refused to step down despite last month’s election loss and losing his mandate in January.

After weeks of negotiations and an incursion by military forces assembled by a West African regional bloc, Jammeh flew to Equatorial Guinea on Saturday.

As part of his deal to leave peacefully, he was assured immunity from prosecution and as Equatorial Guinea is not a member of the International Criminal Court he could not be extradited for crimes against humanity.
