Fielding questions about the announcement on Monday that state-owned Corvinus signed a term sheet for the acquisition of a 49% stake in Vodafone Magyarország, Gulyás said "the opportunity would not have arisen a year and a half later, or the chances of it arising would have been slim".

He said the deal in the making fits well with the government's economic activities as it boosts domestic ownership in a strategic sector and gives the state a stake in a company that "can stand on its own feet".

He added that the transaction would have a "positive" impact on consumer tariffs, but the scale of that impact couldn't be determined yet.

Asked whether the state would use credit to buy the stake in Vodafone Magyarország, Gulyás said the assumption "is not far from reality".

Corvinus and listed IT company 4iG entered into non-binding heads of terms with Vodafone Group to acquire 100% of the telco's Hungarian unit for a cash consideration equivalent to an enterprise value of HUF 715 bln.
