The BBC has apparently been influenced in its decision by the howls of outrage from the British right-wing, upset by the implied disrespect of their patron, St. Margaret, that airing the full song, the usual practice of the show for rising songs, would demonstrate.
Compounding the craven capitulation is this disingenuous and self-serving remark by Tony Hall, the BBC's director general (italics mine):
"I understand the concerns about this campaign (the massive purchasing of the song to celebrate the week's major event). I personally believe it is distasteful and inappropriate.
"However, I do believe it would be wrong to ban the song outright as free speech is an important principle and a ban would only give it more publicity."
So in Mr. Hall's world, a little betrayal of public trust and integrity is okay. Hmm, sounds like just another politician ascending the ladder to me.
For those who cannot muster any sorrow for Maggie's passing, enjoy the following video which, I think, rather effectively captures the animus the Iron Lady was so adept at fostering:
