Equatorial Guinea at polls

Voters in the tiny Central African state of Equatorial Guinea are going to the polls to choose a new president.

The incumbent leader, Teodoro Obiang Nguema, is seeking to extend his 23-year presidency.

He is facing four challengers.

The opposition Convergence for Social Democracy has accused President Obiang and his governing Democratic Party of intimidation, falsifying voting lists and monopolising Equatorial Guinea's recently-discovered oil wealth.

President Obiang seized the presidency in a coup in 1979, overthrowing his uncle, Francisco Macias Nguema, who led the country to independence from Spain.

He has been twice elected as president - both times winning more than 97% of the vote.
