Natural gas tariffs won't rise in France by more than the rate of inflation, French newspapers said Thursday, reporting remarks made by Prime Minister Jean-Marc Ayrault in a TV interview overnight.

France 's year-on-year rate of inflation was 1.9% in May, according to latest data from the National Statistics Institute.

French gas utility GDF-Suez (GSZ.FR) has been pushing the present government as well as the previous administration for higher tariff increases. In June, it lobbied the French Energy Regulation Commission for a 5% increase.
