Presidential hopeful Alberto Fernández on Sunday put his foot down against what he perceived as the "demonisation" of members of his Frente de Todos (Front for All) coalition, insisting voters should instead fear the Mauricio Macri government.
"There is a huge demonisation of La Cámpora", he said in relation to the youth movement led by lawmaker Máximo Kirchner, the son of his running mate Cristina Fernández de Kirchner.
"In reality, people should fear Macri", Fernández told Radio Con Vos.
"What people should fear is all the officials surrounding Macri, including [Buenos Aires province Governor Maria Eugenia] Vidal. They should fear the debt in the province of Buenos Aires which has doubled" under Vidal, he charged.
Fernández's comments come as an unofficial economic adviser in his team, high-profile economist Guillermo Nielsen, described the candidate to take on Vidal in the province, fellow economist Axel Kicillof, as "ignorant".
Nielsen had also previously to the need for the next government to reform Argentina's labour system, a proposal Fernández on Sunday rejected.
"In a paralysed country like ours, everything comes with a huge cost. Everything costs money because we're not selling. We have to get the economy starting again and not think about any labour reform", he charged.
