Boluarte took office on Wednesday when Congress impeached her predecessor Pedro Castillo just hours after his failed attempt to dissolve the legislature, reports Xinhua news agency.

Castillo, who was then detained by security forces, had said earlier that the impeachment motion approved by the opposition-led Congress "is part of the political game" against him.

Boluarte's remarks on early election came as protests broke out along parts of the Pan-American Highway in Peru's Arequipa, Ica and Tacna regions, where residents have put up road blocks with stones, sticks and tires to show their opposition to Castillo's arrest and demand his release.

Boluarte called for calm, arguing her assumption of presidency was in keeping with the Constitution, and the political crisis was not brought about by her.
