The sole challenger to the incumbent General Secretary of the National Democratic Congress says there will be an electoral earthquake on Saturday, December 20 when the ruling party goes to congress to elect national executives.

He says he will secure 60 per cent of the total valid votes to be cast to wrestle power from Johnson Asiedu Nketia, popularly known as General Mosquito.

Abdullah Ishaq Farrakhan took all party members by surprise when he picked nomination forms to contest General Mosquito, who had hitherto been tagged untouchable.

“My chances are 60 per cent clear,” Mr Farrakhan told journalists after vetting on Tuesday.

“I will be beating him by 60 per cent from the total votes.”

General Mosquito, however, remains favourite on most pundits' scorecard for General Secretary.

The Former Member of Parliament told journalists on Tuesday after his vetting that he sees a great potential in his contender.

“I wish him well,” he said.

He disclosed that he has taken Mr Farrakhan around his office to get him familiarized with where he would be working if he won the election to be held in Kumasi.
