Although aviation and travel sectors have been hit the hardest amid the pandemic, this recent travel ban came in the wake of new COVID-19 strain spreading further.
Stressing on the road map of lockdown, Johnson said, "This is part of the roadmap's second step and it will take place at least five weeks after the first step—March 8—but could be postponed if the prime minister and his advisers say it is necessary."
He also added that the United Kingdom and other governments must set out sector-specific support to help ensure there are viable airports to be able to restart.
Meanwhile, Johnson also added that the government's Global Travel Taskforce will reconvene to issue a report by April 12, recommending how international trips can resume safely.
