The comments come after la Repubblica newspaper reported on Monday that the commission is ready to open an excessive-deficit procedure against Rome unless it commits by Feb. 1 to cutting its deficit by an extra 3.4 billion euros (£3 billion) this year.

The Treasury official, who asked not to be named, said Rome and the commission were "assessing the opportune steps" to avoid being put on the commission's blacklist, while avoiding "restrictive budget measures".

Rome has not received any formal letter from the commission, the official added.
