Is George Osborne correct to say workers will be £2,000 a year better off?

The IFS and Resolution Foundation thinktanks say the chancellor's welfare overhaul will leave many families worse off. Do the government's claims add up?

Here is what George Osborne said when he was interviewed on the BBC Radio 4's Today programme on Monday morning: "The typical family with someone working full-time on the minimum wage will be better off, not just a little bit better off but 2,000 a year better off, if you include the lower taxes we are providing through the personal allowance; the childcare for three and four-year-olds. That family is supported." He also said nine in 10 families would be better off once the whole budget was considered.
