The draft deal offers Britain the chance to temporarily limit paying some welfare benefits to immigrants from other EU countries because the "exceptional inflow of workers" to Britain in recent years has placed the U.K. welfare system under a severe strain. [...] the draft text says the limit would apply only to workers who arrive in the future, not those already there, potentially a problem for British Prime Minister David Cameron. [...] the text says the limit would apply for X'' years — the specific number has not yet been agreed. [...] going into Thursday's summit, chunks of the draft saying that financial decisions and governance in non-eurozone countries are a "matter for their own authorities and own budgetary responsibility" are in square brackets, indicating that they have not yet been agreed upon.
