Easily duped, deceived or gullible is the perfect description of "green", worthy of inclusion in the coming Labour manifesto. Put simply, a commitment to global environmental politics and a claim to be a supporter of the current Brown administration is a contradiction. If you are "green" and still believe the government's environmental credentials are intact, then you may as well be wearing a green T-shirt with the words "duped, deceived, gullible - and happy" written proudly across the back and front.
As the actress and New Labour supporter Emma Thompson put it, the decision on Heathrow's third runway, which has been under discussion inside the government since 2002, is the "most egregious piece of hypocrisy I've seen in a long time".
Last September, with his leadership in question, Gordon Brown promised a "transformation in our use of energy" in a "great and historic endeavour". If he repeats the promise, only the greens will applaud - those wearing the "duped, but happy" T-shirts.
Labour's political ideology on green politics and specific environmental goals is clear. This is a party that knows about global environmental protection. It knows the meaning of green. At least that's the assurances that were given - till now.
