Hope the above helped - i was touch typing the broadcast for all.
Will advise from next week to cancel over 500 people gathering in Scotland. Not because of the science but for wider reasons which are important - consistency of public messaging at a time like this. If advising to self isolate, and in other ways that life has to change, it is inconsistent to have a business as usual messaging regarding large gatherings.
At certain events, whether they need ambulance cover, it has an impact on emergency services - at a time when pressure is considerable, it is incumbent upon government to remove unnecessary burdens.
