LONDON (Reuters) – Britain’s government have brought in quarantine rules to protect public health, a spokesman for Prime Minister Boris Johnson said on Friday, declining to comment on legal action brought by British Airways, easyJet and Ryanair.

“I would emphasize that we’ve obviously brought these quarantine rules into place to protect public health and ensure we don’t import the virus as cases in the community reduce,” the spokesman told reporters, adding that the government does not comment on “ongoing legal matters”.
