The government's controversial legislation to slash benefits and get more people into work has now been published.
The plans will impact more than three million households - and the government faces quite the battle to convince dozens of Labour MPs to back it.
Liz Kendall, the welfare secretary, has set out proposals to cut 拢5bn from the welfare budget - which she has said is "unsustainable" and "trapping people in welfare dependency".
Disabled people claiming PIP, the personal independence payment which helps people - some of them working - with the increased costs of daily living, face having their awards reviewed from the end of next year.
An estimated 800,000 current and future PIP recipients will lose an average of 拢4,500 a year, according to a government assessment.

The government also intends to freeze the health element of Universal Credit, claimed by more than two million people, at 拢97 a week during this parliament, and cut the rate to 拢50 for new claimants.
Under pressure from Labour MPs concerned particularly that changes to PIP will drive families into poverty, Ms Kendall will announce new protections in the bill today.
Sky News understands they include a 13-week transition period for those losing PIP; a higher rate of Universal Credit for people with the most serious conditions; and a commitment that disabled people who take a job will not immediately lose their benefits.
Some 40 Labour MPs have signed a letter refusing to support the cuts; and dozens of others have concerns, including ministers.
