FORMER Argentinian president Cristina Fernandez launched a new electoral coalition at a huge rally in Buenos Aires on Tuesday.

The leftwinger, whose late husband Nestor Kerchner was president before her, vowed that the new Citizens’ Unity front would put a “brake on neoliberalism.”

Speaking to a packed Arsenal de Llavallol football stadium, Ms Fernandez pledged to fight the unpopular austerity programme of President Mauricio Macri, elected in October 2015.
