For my previous application (inside UK) it wasn't asked in UK Border Agency - Supporting evidence website but it was asked for in application form.
For this application (outside UK), again, it is not asked in UK Border Agency - Visa application guidance website,

and I can't see anything about it mentioned in VAF9 application form,

...but still want be sure so anyone applied before, did you send your police registration certificate or not ? Please inform.
