Jeremy Corbyn raised the “indignity” of a 92-year-old RAF veteran who spent 12 hours on a hospital trolley because there were no beds in a Leicester hospital.
The Labour leader said more than 2,000 patients faced a similar wait last month.
Boris Johnson said MPs had “every sympathy for people in that position”, but most patients “have a fantastic experience” in the NHS.
He spoke of government plans for upgrading and rebuilding 40 hospitals, but Mr Corbyn challenged those figures.
