Seven restriction Gambian gatherings moved in and picked a sole possibility to challenge against long-serving officeholder Yahya Jammeh in presidential surveys in December.
The applicant, Adama Barrow, was chosen through primaries in a tradition went to by 490 agents.
The 51-year-old from the United Democratic Party, the country’s biggest opposition movement, got 308 of the 487 votes cast.
“We have put our differences aside for the interest of this country. Gambians are tired of 22 years of Yahya Jammeh’s misrule and will end it come December 1st when we go to the polls. We all have to put our hands together to save this country from destruction,” he said.
This is the biggest opposition alliance in the history of The Gambia, a former British colony.
Jammeh, 51, came to power in a 1994 coup, and has ruled The Gambia with an iron fist since.
His regime is also regularly accused by rights groups of arranging the forcible disappearance of opponents.
Before the nation’s last presidential vote in 2011, the 15-nation Economic Community of West African States (Ecowas) said Jammeh’s control of the media and intimidation of voters meant the election could not be free and fair.
The strongman took 73% of the vote.
The Gambia’s newly appointed Independent Electoral Commission has assured political parties the upcoming vote will not be rigged, despite fears that an opposition crackdown is already underway.
