Equatorial Guinea called yesterday for the extradition of Mr Moto, who tried to mount a coup against Mr Obiang in 1997 from Angola, for which he was sentenced in absentia to 101 years' jail. He recently set up a "government in exile" in Spain.
Mr Moto denied any involvement in the plot and claimed on Spanish radio that Mr Obiang was an "authentic cannibal" who "systematically eats his political rivals".
"A while back he paid millions to those they call marabou (sorcerers) to tell him if his power-base was safe. They told him that to keep his grip on power he had to kill people close to him," Mr Moto said. "Obiang wants me to go back to Guinea and eat my testicles. That's clear."
And we thought this campaign was getting nasty.
