WATCH: Drive-through testing facilities for NHS staff at Chessington and North Greenwich virtually empty at 4pm. Wembley was also empty.

Considering the government says it is massively ramping up testing, this looks very, very odd.

Yesterday there were issues with staff turning up only to be told they had to have a set appointment. We're chasing NHS England for an explanation, but are workers simply finding the system too difficult to use?

Understand there are "teething problems" at the new sites. Traffic is deliberately being managed to avoid queues and spread of the virus, but even so, something appears to be badly wrong if the bays are this empty.
