The Government's website does not provide any information on the composition of the SAGE group. It does however mention the composition of the New and Emerging Respiratory Virus Threats Advisory Group (NERVTAG) and it can be fund with the following link.

I do not recognize any names in the NERVTAG Advisory Group but it does provide information on the NERVTAG members' biographies.
I mentioned Wikipedia (by the way, I have no problem with it) as it does provide the name of the participating scientists in SAGE and I recognized two names, namely, of course, Sir Patrick Vallance and Professor Chris Whitty, which we all recognize. It also has a link to NERVTAG as well as COBR (Cabinet Office Briefing Rooms).
This entry in Wikipedia is based on the article provided by the Guardian earlier this month. Wikipedia does not hide it, on the contrary. Rather open and transparent, would you say?
