Although PT deliberately never identified itself with a particular brand of leftism, it nevertheless "always defined itself as socialist" and espoused many radical positions. For example, at the Brazilian Constituent Assembly of 1988 it advocated repudiation of Brazil's external debt, nationalization of the country's banks and mineral wealth and a radical land reform. In addition, as a form of protest and as a signal that the party did not fully accept the "rules of the game" PT's delegates refused to sign the draft constitution.
