African Union envoy Raila Odinga ended his 48-hr long visit to Ivory Coast this week after it failed to yield results following talks with the nation's rival leaders Laurent Gbagbo and Alassane Ouattara.

A proposal for talks was delivered by Odinga on Monday on a fresh round of mediation to persuade Gbagbo to step down.

But why do these talks keep failing? Gado, our cartoonist this week, seems to have a pretty good idea about it.

Gado, real name Godfrey Mwampembwa, is one of Africa's most influential cartoonists. He draws a daily cartoon for Kenyan newspaper The Nation, and his work has been published in Le Monde (France), the Washington Times (US) and the Japan Times, to name a few.

Gado also came up with the XYZ Show, a satirical tv show commenting on current affairs and politics. He was named Kenyan cartoonist of the year in 1999, and received the Dutch 'Prins Claus Award' in 2007.

"I draw because I want to say something. My drawings are my tools." says the Tanzanian-born cartoonist.
