All smiles for Yvette Cooper

I’ve been in Westminster since 6.30am, a time when anyone awake is crying out for coffee and looking like death. But two metres in front of me now stands the biggest smile I have seen all day. Yvette Cooper was careful not to beam as much on camera, but was a ray of sunlight as she came bouncing up the stairs to the Sky News stage (where I have been doing a paper review). She is tipped for a big job today – probably DWP – and what a day, I suspect, it will be for the Balls-Cooper axis.
