In a damning report issued on Tuesday (26 July), parliament’s public accounts committee said despite spending "at least £486 million" on implementing the scheme, government still "does not know whether the system worked or whether the cost was worth the disruption caused".
The committee highlighted, in particular, the impact on travel, noting how government-imposed travel rules changed more than 10 times between February 2021 and January 2022 "giving the travel industry little time to react".
