Under the recently adopted “two-pack” legislation, the Commission will have to sign off on national budgets before they are approved by parliaments. This is a more intrusive role than the US federal government has vis-à-vis the states. Fiscal policies are at the centre of the contract because trust in the currency requires trust in the sovereign.
I would encourage you to aim for a consistent implementation of the internationally agreed standards, so as to ensure a level playing field worldwide and to reduce options and national discretions as far as possible.
