Sshhhh!

At first Hilary Benn's answer to John Grogan's question, trying to smoke out Benn's opposition to Heathrow expansion looks like a non-answer.

To ask the Secretary of State for Environment, Food and Rural Affairs what discussions he has had with the Secretary of State for Transport on the effects on air quality in the area around Heathrow of the proposed third runway.

I have regular discussions with ministerial colleagues about air quality and noise in relation to transport, including plans around Heathrow.

But Grogan didn't ask Benn about noise. Is Benn saying: don't forget the noise John?
