Prime Minister Boris Johnson stood by his description of Britain's system of testing and tracing coronavirus infections on Thursday, despite a fall in the number of people contacted by tracers.
Asked whether, in light of the latest data, he thought it was still a world beating system, Johnson said: "If you look at what we're doing, actually I think it certainly is and it certainly does fit that description as world beating."
