unanimous support for a deal between the UK and the EU says Donald Tusk
David Cameron said he would recommend the deal, which said gives the UK "special status" in the EU, to his cabinet on Saturday.
The agreement reached following drawn-out negotiations in Brussels paves the way for the UK's EU referendum.
Downing Street said it included a "brake" on welfare payments that can apply for seven years.
Another sticking point, child benefit curbs, will apply to existing claimants from the start of 2020.
