José Antonio Kast proposed the "Plan Implacable", a security package to expand police and military powers as he leads the runoff against Jeannette Jara.Kast has consolidated endorsements from Johannes Kaiser and Evelyn Matthei and draws early support from Franco Parisi’s voters as Ipsos polls show crime and migration top public concerns and he pledges to expel about 340,000 irregular migrants.Mapuche leaders Karen Rivas Catalán and Angelina Cayuqueo warn the plan risks reviving Pinochet-era tactics, emergency powers, mass deportations and setbacks to land restitution if a right-leaning Congress pursues spending cuts.
