“Election  results  are  compiled  and  tabulated  behind  closed  doors  with  no  candidate representatives or independent witnesses present, exacerbating a lack of transparency in the overall process. Authorities should make the tabulation and compilation of votes at all stages more accessible.”

In 2017 Presidential Elections, 13,000 polling stations were equipped with electronic equipment to count votes digitally. There is no further data on how these results were transmitted to higher levels.
