I agree with youngmafbog though. It would then become competitive and if the chosen song was outsold by the Witch is Dead it would satisfy the Thatcher haters even more. It's better to rise above it.
Personally i don't mind if the BBC plays it during the chart show, but i don't think it should make any comments. If it doesn't play it Radio 1 shouldn't comment either, other than to say "...that was Duke Dumont at number 4, at number 3 it's a new entry for Judy Garland, and staying at number two here's Pink with Give Me a Reason...
