What are the Pip and universal credit changes and who is affected?

The chancellor, Rachel Reeves, has set out more details about planned benefit cuts as part of her Spring Statement.
The government had already announced that changes to a key disability benefit called Personal Independence Payment (Pip) and Universal Credit (UC) would save around £5bn a year by the end of 2030 and get more people into work.
Overall, the government estimates that 3.2 million families will be worse off as a result of the reforms by 2030 while 3.8 million families will be better off.
Pip is paid to more than 3.6 million people who have a long-term physical or mental health condition in England, Wales and Northern Ireland.
There are two elements – a daily living component and a mobility component. Claimants may be eligible for one or both.
