Sergio Massa and Javier Milei debated for the last time before next Sunday's runoff.

The presidential hopefuls talked about pre-agreed topics: Economy, Security, International Relations, Human Rights and Education, among other areas.

Massa, the pro-government candidate, emerged as the winner, according to most of the media and analysts.

In this context, the libertarian ratified, in response to a question from his rival, his intention to eliminate the Central Bank and to replace the peso with the dollar.

He also generated controversy when he admitted that he admired the late former British Prime Minister Margaret Thatcher.

Milei also asserted that the current government committed what he called "a crime against humanity" by ordering preventive isolation during the Covid pandemic.

Meanwhile, Massa ratified that if elected, he will call for a government of national unity with members of other political forces.

And promised that, if he is President, he will increase investment in public education, which he claimed as one of Argentina's greatest assets.

Regarding relations with the world, Milei was criticized for anticipating that he would not maintain ties with Brazil or China because their governments are "leftist".

Milei dismissed the criticisms by asserting that economic negotiations with other countries will be made between private parties, not between States.

But Massa reminded him that it is the governments that set the tariff and trade policies on which these exchanges are based.

This week the electoral campaign ends and on Sunday will be the second round, from which will emerge the successor of Alberto Fernández, to take office on December 10.
