John Fru Ndi has lead Cameroon's opposition Social Democratic Front (SDF) for the past 20 years.
In that time his party has failed to make any significant dents in President Paul Biya's substantial majority.
The president is expected in the SDF stronghold, Bamenda, in the North West Province next week for the first time in 25 years.
