premise: British Prime Minister Tony Blair was praised abroad and vilified at home on Saturday for clinching an EU budget deal, while German Chancellor Angela Merkel was applauded as a key mediator.
  Acting as EU president until the end of the month, Blair sealed agreement overnight on a tighter 2007-2013 spending package with a mechanism to review and perhaps modernise it during the seven-year term.
  But it was his decision, under heavy domestic fire, to give up more of Britain's beloved multi-billion euro annual rebate which drew most comment.
  "The British presidency deserves praise for its constructive role in a complicated negotiation and for the courage it showed in giving up part of its rebate," Greek Prime Minister Costas Caramanlis said.
  European Commission head Jose Manuel Barroso was disappointed that the deal, which represents 1.045 percent of gross national income, was not as big as his EU executive team had sought, but hailed Blair nonetheless.
   What is one possible outcome of a future review of the spending package?
hypothesis: perhaps modernise it
