Did someone send David Cameron the wrong media grid for the week?

I only ask because:

1. Unemployment  down (good news)
2. Inflation down (seen as good news even if some may differ)
3. New railway investment plans published
4. Big move to boost infrastructure spending from the autumn onwards

All sounds for the making of a week of good economic news. So what does David Cameron do? He gives a media interview full of economic doom and gloom.

Very strange timing.
