Guyana's president and opposition leader after a contentious period have settled on an appointee to head up the country's election commission to carry out new elections following a no-confidence vote last December against sitting president David Granger.

The South American country had been facing considerable political uncertainty on a way forward for the election as it stands on the cusp of becoming a major oil producer following massive oil discoveries operated by ExxonMobil.

After substantial wrangling over potential appointees, outgoing president David Granger on Friday selected Justice Claudette Singh from a list of six nominees generated by opposition leader Bharrat Jagdeo to lead Guyana's elections commission, or Gecom.
