ICU hospital staff: 'Scared, sad, petrified, worried'
For the first since April the UK has recorded more than 1,000 daily Covid-related deaths – one of the highest figures of the pandemic.
Right now, London is at the epicentre of this crisis. Hospitals now have more Covid patients being admitted every day than they did at the peak in April. Many doctors and nurses say they're reaching breaking point.
