One of today’s other stories being looked at by BBC Verify is the government’s planned welfare changes.
There are currently 120 Labour MPs listed as supporting a rebel amendment in the Commons which aims to block the proposals.
The changes – if they go ahead – would tighten the eligibility criteria for receiving personal independence payments (Pip), a benefit that helps people who have a long-term physical or mental health condition with daily living costs.
Prime Minister Sir Keir Starmer says the current welfare system “traps people” on benefits, and was set to fuel “unsustainable” rises in the cost to taxpayers.
The Labour Mayor of London Sir Sadiq Khan, however, says the changes would “destroy” the financial safety net of many disabled and disadvantaged Londoners.
Analysis carried out by the Resolution Foundation suggests that benefit spending is due to rise regardless.
Before the government announced its proposed changes, health and disability-related benefit spending was due to rise from £59bn in 2024-25 to £72bn in 2029-30 (adjusted for inflation).
If the government’s changes come into force, the foundation predicts benefit spending will rise more slowly to £67bn by 2029-30 – a difference of £5bn.
