//Had I known that we could not set our own budget while members of the EU, I might have voted leave//
Then you should have considered your position more carefully:

"In April, all EU Member States present to the Commission the budgetary measures that they intend to implement in order to fulfil their commitments. Those that use the euro as their currency do this through stability programmes, while the rest submit convergence programmes.
At the same time, all EU Member States also submit details of the structural reforms they are planning to boost growth and jobs in ‘National Reform Programmes’. The Commission analyses the two programmes of every country and then makes specific policy recommendations to each of them. Governments discuss these recommendations with the Commission and with each other and then integrate them into their national policies with their parliaments."
Of course, in true EU fashion, the scope and strength of these "recommendations" will only broaden over time.
The last bit is interesting: "Governments discuss these recommendations with the Commission and with each other and then integrate them into their national policies with their parliaments." So no question of not integrating the EU's recommendations into their national policies, it seems.
