I don't think this was a photocall he wanted to miss!
It would be good if the Government agreed a standard for when it is ok for Minister to take flights (Maybe they have done that already?). That would stop the injustified sniping every time somebody takes a flight. It would also make them look more serious about their carbon footprint. Leading by example across the board is a good policy.
I guess the sniping wouldn't stop fully considering how conscientious the Green ministers are and yet they are the ones everybody tries to criticise, e.g. Gormley to Bali and Eamonn Ryan's business class flight. It is up there with Dail Holidays and any increase in anybody's wages for lazy journalism.
