Figures show A&E in England has had 'worst week'
19 December 2014 Last updated at 19:08 GMT
Pressures in England's A&E units have hit record levels, with the lowest percentage of patients seen within four hours since monitoring began in 2010.
Data showed just under 90% of patients were seen within four hours in the seven days up to December 14.
Major units particularly struggled, with just six out of 140 meeting the target to see 95% within four hours.
Performance in Wales and Northern Ireland is even worse, while the picture in Scotland is unclear.
