By all accounts and reactions, the budget seems to be very good, but with this caveat, that if the EU negotiations go wrong, or if the deal is voted down in the House, as has been threatened, all this positive energy will be wasted and all the promises ditched. The budget is, in other words a tantalizing glimpse of what might happen if there is a properly negotiated Brexit in March. In other words, as much of a threat as an offer.
