"Remembrance Day is not long off and the period of poppy wearing will start in a few weeks. It is normal for the BBC to agree dates between which, for those wishing to do so, poppies may be worn on screen.
"This year, David Jordan (Director, Editorial Policy and Standards) suggests that poppies may be worn on screen from 06.00 am on Saturday 29th October to 23.59 on Sunday 13th November - Remembrance Sunday."
(from the BBC's Director of Editorial Policy and Standards)

So now we know, poppy wearing is "for those wishing to wear them". Now the BBC is going to have to designate a token non-poppy wearer, in order to garner some credibility for this line.
