A list revealing some of the members of the group which is advising the government over the coronavirus outbreak has been published.
Names of some members of the Scientific Advisory Group for Emergencies (Sage) has been released by the government following pressure from campaigners demanding transparency over how coronavirus decisions are made.
The group's membership had been kept secret up to this point on security and independence grounds, however individual members had been able to disclose their participation.
Sage is a group of experts providing scientific and technical advice to support decision makers during emergencies.
Membership changes based on the expertise needed to address the crisis the country is faced with.
The government has been receiving advice from Sage twice a week since the first meeting on coronavirus on January 22 - it is the group advising ministers on when to relax lockdown restrictions.
The government website revealing the Sage membership said the list includes "names of participants who provided input as experts at one or more meetings, including public servants who acted in an expert capacity".
The website added how meetings are "also regularly attended by officials from Her Majesty’s Government. These attendees have not been named".
It said permission to publish names was requested from all participants and those who did not give permission have not been named.
Those on the list include well known names such as England's Chief Scientific Advisor Sir Patrick Valance and England's Chief Medical Officer Professor Chris Whitty.
Others on the list are Prof Whitty's deputies Dr Jenny Harries and Professor Jonathan Van Tam, and Public Health England medical director Professor Yvonne Doyle.
Last Saturday it was revealed the prime minister's top aide Dominic Cummings had attended "some meetings".
That sparked calls from opposition MPs for the membership of Sage to be released because, as Labour's shadow health secretary Jon Ashworth said, "ministers have repeatedly claimed timing of lockdown was based on science".
In response to Mr Cummings attending meetings, a former government chief scientific adviser assembled a group of experts to look at how the UK could work its way out of coronavirus lockdown.
Sir David King, who worked under Tony Blair and Gordon Brown, created the board to emphasise the “importance of transparency”.
Commons science and technology committee chairman Greg Clark welcomed the publication of the Sage list.
The Conservative MP said: “I strongly welcome the commitment to transparency made by Sage in publishing the names of the members.
“This was something my committee called for in order to provide public reassurance that Government decisions are informed by a broad and substantial body of expert advice.”
