Video report by ITV News' Health Editor Rachel Younger:
Accident and emergency services in England suffered their worst monthly performance since 2010 in February, new figures reveal.
Just five out of the 138 trusts achieved the standard of seeing 95 per cent of patients within four hours.
An average of 87.8 per cent of patients were seen within the guideline four-hour time period - down from from 92 per cent during the same month last year.
Meanwhile, the total number of A&E attendances during the month was up by 13.1 per cent - up to more than 1.8 million - on the same time period last year, while admissions were up by nine per cent to 463,000.
The latest report from NHS England attributes the rise to there being an extra day in the month, due to 2016 being a leap year.
The report also reveals the best and worst-performing A&E departments, comparing all patients with 'Type 1' patients - the ones in the most life-threatening conditions.
Luton and Dunstable University Hospital Trust and Sheffield Children's Trust were the only two to achieve above the 95 per cent guideline for both Type 1 patients and across the board.
Harrogate and District, Dudley Group of Hospitals and South Warwickshire trusts all achieved 95 per cent across the board.
North Middlesex University Hospital Trust was named as having the worst-performing A&E, only managing to see 67.2 per cent of all patients - including Type 1 - within four hours.
Best-performing A&E departments:
Type 1 performance relates to trusts with a "major A&E department" - which NHS England defines as a consultant led 24 hour service with full resuscitation facilities and designated accommodation for accepting A&E patients.
