The government’s own scientific advisers warned that its 10pm curfew on pubs, bars and restaurants would only have a “marginal impact” on the spread of coronavirus.
Documents published on Monday from the government’s Scientific Advisory Group for Emergencies (Sage) show that experts dismissed the idea of a curfew exactly a week before one was implemented across England.
In a document from 17 September, seven days before the 10pm curfew came into force, Sage wrote: “Curfews likely to have a marginal impact. Low confidence.”
The document was published on Monday just hours after prime minister Boris Johnson announced details of a new three-tier lockdown system in England.

The 10pm curfew has been criticised by scientists, as well as politicians in the North of England, who have doubted its impact on coronavirus rates.
The Sage revelation follows criticism last month that Johnson “never discussed” the curfew with science advisers, one of whom described the plan as “fairly trivial” which would have a “very small impact on the epidemic”.
In a separate Sage document, scientists said NHS Test and Trace was only having a “marginal impact” and would “likely decline futher” unless the system was expanded and people were given support to self-isolate.
It also emerged, through a Sage document dated 21 September, that scientists advised the government to introduce a small “circuit breaker” lockdown in England to halt the spread of COVID-19.
The Labour Party accused the government of dismissing the advice of its own scientists.
Shadow health secretary Jonathan Ashworth said: “The government now needs to urgently explain why it ignored its own scientists and what it will be doing to get control of the virus.”
Johnson had promised the test and trace scheme would be “world beating”, but Sage experts wrote on 21 September: “The relatively low levels of engagement with the system… coupled with testing delays and likely poor rates of adherence with self-isolation suggests that this system is having a marginal impact on transmission at the moment.”
Sage added: “Unless the system grows at the same rate as the epidemic, and support is given to people to enable them to adhere to self-isolation, it is likely that the impact of Test, Trace and Isolate will further decline in the future.”
The criticism increases the pressure on Baroness Harding, the Conservative peer who chairs the £12bn scheme.
Ashworth said: “This is yet further evidence that the government’s incompetence is hampering our response to a second wave.
“Sage have essentially confirmed test and trace is not functioning adequately as we have been warning for months.
“Ministers need to get a grip of testing so we can get control of the virus.”
The latest figures show NHS Test And Trace in England had suffered its worst week for the proportion of contacts it successfully manages to track down.
