Keiko Fujimori is the front running candidate in Peru's upcoming April 10 election.
Demonstrators gather against presidential candidacy of Keiko Fujimori at San Martin Square. Fujimori, the 40-year-old center-right daughter of imprisoned ex-president Alberto Fujimori, has long enjoyed a double-digit lead over her nine rivals.
But she has struggled to distance herself from the dark legacy of her father, who is serving a 25-year sentence for human rights abuses and corruption in his 1990-2000 government and is not expected to win outright on April 10.
Protesters hold signs against Keiko Fujimori, reading "Keiko is not going (to be president)".
Hostility from Peruvians who loathe Fujimori's father and blame her for the disqualification of two of her rivals mean she is vulnerable in a second-round vote if she fails to get at least 50 percent of all valid ballots in the first round.
Protesters representing corruption perform during the march.
The head of the Organization of American States said next week's presidential election in Peru could lack credibility unless two recently-disqualified candidates are allowed to run.
OAS Secretary General Luis Almagro called on Peru to avoid a "semi-democratic" election April 10 and re-establish the political rights of Julio Guzman and another candidate barred from running last month for violating electoral laws.

Fujimori has also come under scrutiny for allegedly handing out cash at a rally but the nation's top electoral authority April 1 reaffirmed an earlier ruling clearing her of any wrongdoing.
