LIMA (Reuters) - Peruvian presidential election front-runner, socialist Pedro Castillo, said on Saturday he would, if elected, review contracts with foreign miners in the copper-rich country and seal a deal for Russia's Sputnik V vaccine.

Castillo leads in the polls ahead of a run-off vote on June 6 against right-wing opponent Keiko Fujimori, in a polarized election that could move the Andean nation sharply to the left, a trend that has rattled markets and worried miners.
