The action caused an outrage in his country as well as all over Africa.President Buhari of Nigeria and a selected few leaders of Africa including the leader of Liberia payed him a visit to appeal to him to do the honorable thing.
But still,he remained adamant in his stance.Absolute power corrupts absolutely,especially in Africa.
The diplomats' move comes in the wake of Mr Jammeh's decision to challenge the outcome of the 1 December presidential election, which he had initially accepted - even congratulating Mr Barrow.
Now in a new development,serving Gambian diplomats in a joint appeal letter appealed to the leader.These ambassadors included those to, Beijing, London, New York, Moscow and Brussels.
The letter reads: We... strongly appeal for you to accept the choice of The Gambian people and facilitate a peaceful transfer of power to the President-Elect, Mr Adama Barrow."
The tone of their appeal is diplomatic rather than hawkish and credits President Jammeh's initial response to the result:
Your statesmanly and televised acceptance of the election results in favour of the coalition candidate on 2nd December, was acclaimed and applauded throughout the world.
The fact that you further congratulated Mr Barrow on his victory and assured him of your support and guidance was testimony to the fact that you care for the progressive development of The Gambia in a peaceful and orderly transition."
Efforts by the regional grouping, Ecowas, to convince Mr Jammeh to step down have so far been unsuccessful.
In a further interesting development,the man who won the election,Adama Barrow remarked that if the stubborn leader does not leave his office by January when he is supposed to be sworn in as the new President,he will declare himself as president and Yahya as a rebel leader.
I just really hope this is not going to lead to an African war of killing and looting.Beacuse it is the ordinary people who will suffer as they always do.
I have no idea why African leaders keep disgracing the continent with their greed and inhumanity.
