BRASILIA, Brazil, May 3 (Reuters) Brazil is set to have its first woman president -- just for one day -- when Supreme Court head Ellen Gracie Northfleet assumes the national leadership tomorrow while President Luiz Inacio Lula da Silva travels to Argentina.
Northfleet is fourth in line in the constitutional order behind vice-president Jose Alencar, Upper House president Aldo Rebello and Senate president Renan Calheiros.
The three men have been invited to accompany Lula to Argentina for a meeting tomorrow with other South American leaders on Bolivia's nationalization of its energy sector.
Two have accepted and only Calheiros has still to officially confirm.
''It is a mark of sexual equality. I think it will be a symbolic moment,'' Northfleet told reporters at Congress.
