The co-founder of the Covid testing centre at Gatwick Airport has apologised for delays in its service.

ExpressTest has said it is hoping to increase the capacity of its test centre at Gatwick’s South Terminal car park in the next week.

The testing facility is available for people who needed a valid, negative Covid-19 test certificate up to 96 hours before travel.

120,000 people had tried to book a test within the first few days of them opening on 27 November.
