Damning line from the OBR this: "We have assessed that none of the policy measures in this Budget have a sufficiently material impact to justify adjusting our post-measures potential output forecast."

Ie it's a budget which does nothing new for growth.

Everyone needs to calm down a bit. It’s an embarrassing and stupid leak. But we knew all the detail anyway- the Treasury had leaked it. Markets have reacted well. This bit of process won’t be anything close to the most politically difficult thing about today.
