Watching Sky News. Reports released today admits that for closing ceremony, no public admitted, for 'security reasons. 
And for Usain Bolt 100m , none, for security reasons.
And for when we won medals for Ennis and Farah, something like 2-3% public and 98% VIP.
I am not sure my fatcs/figures are totally correct, but that was the jist of the news I just saw.
And many of those werent even taken by the VIP's.
Plus, All those emprty seats we saw. All throughout, remember the diving etc.
But, hey Seb Coe got his award on sports personality of the year, so that's o.k., right?
