Peruvian presidential candidate Keiko Fujimori asked election authorities Wednesday to annul the results from 802 polling stations, the equivalent of 200,000 votes, according to local media.

Fujimori made the announcement at a press conference in Lima, as the most recent official results from Sunday's election show 49.7 percent support for her against 50.2 percent support for Castillo, with the results from 99 percent of all polling stations counted.
