The prime minister highlighted an existing target for the NHS in England that 92% of patients waiting for planned treatment should be seen within 18 weeks of being referred.
It was a manifesto pledge and the government has pledged to achieve it by 2029.
The latest NHS data shows that in September 2024 only 58.5% of operations, or other procedures people were waiting for, occurred within 18 weeks.
When Labour took power in July, the share was 58.8%, so it has barely changed.
The last time the 92% target was hit was in November 2015.
