In January just 85.1% of patients who went to A&E were seen within four hours making it the worst month on record.
The target for A&E is to have 95% of patients seen within four hours, Sky News said.
However there was an increase in emergency admissions in January of 1.5% compared to January 2016.
The previous worst month was December 2016, when the percentage of four-hour assessments fell to 86.2%, according to NHS England Data cited by The Independent.
In addition, ambulance response times for the most serious calls were below their target, as just 66.7% arrived within eight minutes. Their target is 75%.
In February the British Medical Association said the Government had “failed to grasp the seriousness” of severe pressures on NHS hospitals, while the British Red Cross has said the health service is locked in a "humanitarian crisis" brought on by lack of funding.
