WATCH: Are people watching Euro 2020 at home contributing to Covid spike?
Stephen Reicher from St Andrews University is telling us that data suggests it's not the people in the stadium, but rather those at home who are more likely to be driving figures up.
It could be people watching at home, not those in stadiums, driving a Euro 2020 Covid case spike, according to a St Andrews University Professor.
Stephen Reicher is also a member of the SAGE subcommittee advising on behavioral science.
He's telling us that data suggests Euro 2020 viewing could be a part of the current spike across the country of coronavirus infections.
For the majority of the pandemic cases have been quite evenly split between men and women, but in recent days men aged 15-50 have seen 2-3 times more cases.
Reicher believes this is the kind of people most likely to meet in groups, and potentially be drinking, to watch the football.
Due to the many of these meetings being unmanaged and untracked, and much more likely to get out of hand, Reicher believes it's a far bigger potential issue than those sitting in the stands.
