"If the opposition party believes that we don't have the majority, it has the tools - as provided by our democratic system - to question it but I consider that the deal will have the broad support of the parliament," Environment and Energy Minister Giorgos Stathakis told SKAI television on Wednesday.

"The government has the full legitimacy to sign the deal. The agreement will be ratified in parliament and we believe that it will be backed by a broader majority," said Stathakis.
