Where Is The Shadow Chancellor?

Where is Ed Balls, The shadow Chancellor is normally on twitter banging on about the economy

After 3 damaging yrs of flatlining these growth forecasts welcome but for millions there's no recovery at all http://t.co/aP9bSSHFJR

But since then :

Nothing on the econmey, plenty of visits and campaigning photos, but no tweet on his brief as shadow Chancellor , even Ed Miliband managed a "#freezethebill " tweet :

Loved seeing photos of #freezethatbill campaigning from across the country today. Let's keep the pressure up!

Has Ed Balls been sidelined or is it that just has nothing to say?
