The government spent nearly half a billion pounds of tax payers money on the Covid traffic light system for international travel and yet it "does not know" whether it was a success, an MPs' committee said.
The traffic light system was expensive for tax payers and visitors to the UK while critics pointed to other European countries that imposed less strict procedures.
Testing and quarantine requirements for people arriving in the UK were changed 10 times between February 2021 and January 2022, a report by the Public Accounts Committee (PAC) stated.
