Casualty viewers have expressed disappointment over tonight's improvised episode having competed against England's World Cup quarter-final match in the schedules.
The latest episode of the BBC show saw the cast improvise their lines. It explored the pressure that paramedics and other frontline staff are under within the NHS.
It highlighted, amongst other things, ambulance queues outside hospitals. The episode was set across four days and focused on paramedics Jan (Di Botcher), Sah (Arin Smethurst), Teddy (Milo Clarke) and Iain (Michael Stevenson).
