The London Ambulance Service had its busiest day in history on Friday as scorching temperatures soared across the capital amid a record-breaking June heatwave.
The service received 8,869 emergency calls and responded to 688 life-threatening incidents, including people in cardiac arrest or who have stopped breathing.
Between 6pm and midnight they answered more than 500 calls an hour.
Friday was the hottest June day on record, which reached a blistering 37.3C in Suffolk, the Met Office said.
The emergency service wrote on Saturday on X: ‘Yesterday was our busiest day in history. Thank you to all our crews and call handlers.
‘Please only use 999 in a life-threatening emergency.’
