Since first watching the clip posted yesterday (see below) illustrating the risks a speaker runs in having members of the audience sitting behind him, I've noticed something else - namely that Kenneth Clarke not only fails to nod in agreement when William Hague and others do, but is also the only member of the shadow cabinet who doesn't bother to get his hands apart and join in the delayed burst of applause.
Whether or not there's any significance in this, I have no idea, but I do know that not applauding can be an accountable matter that has been known to result in a politician being interrogated about it - as when Peter Snow 'merely observed' that Francis Pym had not been clapping vigorously enough during a conference speech by the then Chancellor of the Exchequer, Sir Geoffrey Howe (HERE).
Competitors are invited to watch the whole of yesterday's speech by David Cameron's - which can be seen HERE - and then follow Peter Snow's example by seeing if there's anything else you can 'merely observe' about the behavior and/or facial expressions of those in the audience sitting behind him.
Your observation(s) may be entered in the blog comments section and/or emailed directly to me (via the link in 'My complete profile' on the top left of this page).
