       “With hindsight I should have sent everyone back inside. I should have found some other way to thank them.

       “I should have recognised that even if it could be said technically to fall within the guidance, there are millions and millions of people who simply would not see it that way, people who have suffered terribly, people who were forbidden from meeting loved ones at all inside or outside, and to them and to this House I offer my heartfelt apologies.
