According to a report by Messaggero

That's not much of a surprise really as it has been well established by now that Tria wants to keep the budget deficit between 1.5% to 1.8%. The major dispute now is that of the citizens' income proposal which Di Maio and his Five-Star Movement party wants to push forward with.

The proposal would amount to roughly a 1.5% deficit in itself already and mess up Tria's plans. Eventually, something's gotta give and time is starting to run out. It's going to be a really interesting showdown in the coming week. If there is any major sacking/resignation to come, expect this to have some minor impact on the euro.
