The Brazilian Socialist Party is likely to announce environmentalist Marina Silva as its presidential candidate this week, replacing party leader Eduardo Campos who was killed in a plane clash, three leading local newspapers reported yesterday.

Silva's candidacy is likely to be formally announced at a party meeting this week, the Folha de S Paulo said. The newspaper added that her running mate is expected to be Beto Albuquerque, a Brazilian Socialist Party congressman from the southern state of Rio Grande do Sul.
