Salvini against the "traitors of the Homeland": refers to Conte or Metropol?

Salvini and Meloni set off to attack Conte, who would have signed an agreement to modify the Mes, the European Stabilization Mechanism, also known as the State Savings Fund, without Parliament's authorization. Enough to make Salvini scream of 'high treason' and to evoke the prison for the premier: "If someone puts us in this cage of the Mes, the government bonds risk being worth less and less," said Salvini: "If anyone he has signed in the dark about the people and Parliament say so now, otherwise it will be high treason and for the traitors in peace and war the right place is jail ".
"Come to parliament and tell it: I have signed or I have not signed, and then you go back – adds the leader of the League, the same one who for months refuses to go and report to Parliament on the case of the Russiagate – from now every day we will ask if he and some ministers put the heads of the Italians on the table ".
"This affair, we of the League will not let it pass in silence, waiting for Rai, Mediaset, La7 to talk about it. The League has not given any authorization, we will go all the way", because "someone has signed to put it in that place to the Italian. "

The subject also speaks Giorgia Meloni: "Conte has given ok to reform Fund save states (Mes) without involving the Parliament, which by December will be called to ratify this new eurofollia: an all-powerful super Troika. Fdi will barricade against yet another betrayal of the people . #StopMes ", tweeted the leader of the Brothers of Italy.

League buffaloes
Something is not back in the reconstruction that makes Salvini of this 'betrayal'. In fact, Conte would have signed the Mes reform several months ago, when it was the League in government and not the Democratic Party. It was Tria the Minister at the time and Claudio Borghi (Lega) last July had presented a question to Tria to find out whether he had actually opposed the reform of the Mes. The agreement, Tria had said, would have been reached by the end of 2019, so in July it certainly wasn't there.
And there is not even now, since for the ratification the authorization of the Parliament is needed. So, has Conte really signed this document? And if he had really signed it, it would have happened when the League was in government: how is it possible that nobody noticed anything when we know for sure that Borghi knew about it, given that he presented the question to Tria?
What is the Mes
The Mes is a mechanism that works as a 'rescue' for countries in economic difficulty but has the peculiarity that to be activated, the very strict parameters of the Maastricht Treaty must be respected, the same ones against which the League has been lashing for years, since they represent the necessary constraint to be able to leave the euro. Usicre dal Mes would mean finding oneself without the possibility of accessing this fund.
