French state-controlled natural gas operator Gaz de France's (1020848.FR) Chief Executive Jean-Francois Cirelli said a gas regulated tariff hike in France is likely before July, due to the high oil crude prices, in an interview with French daily Le Parisien on Wednesday.
But Gaz de France didn't request any tariff increase, Cirelli added.
Cirelli also said he was confident that Gaz de France's merger process with French utility Suez (SZE.FR) would be smooth.
