How to nobble a political rival in Africa and get away with it

“THE MOST dangerous precedent in the political history of Senegal,” was how El Malick Ndiaye, a spokesman for Senegal’s main opposition party, described the decision. If that sounds like hyperbole, it should not. On January 20th Senegal’s Constitutional Council ruled that Ousmane Sonko, an opposition leader, could not stand in the presidential election in February because of a conviction for defamation.Mr Sonko, who is now in jail and whose party has been dissolved, has also been convicted of “corruption of youth”, which is defined as immoral behaviour with someone under the age of 21. He says these and fresh charges, including fomenting insurrection, are politically motivated. The government disagrees.
