But it is.
Does the "...and..." in that phrase mean:
(a) "set it, readback i.a.w. CAP413 then shutup"
or;(b) "set it, then shutup (NB: I wish you to ignore SOP in this unusual instance, but I don't intend to explicitly tell you that)"
If anyone is planning on answering that question, feel free to parse the phrase as part of your answer.

Clearly not - the differing interpretations on this thread show that.
IMO I think the poorest ATCO behaviour described in this thread is this:
Gertie wrote:I had a "squawk and standby" today from Norwich. It was quite clear he didn't expect me to read back because he immediately started talking to someone else. (As a separate, new, transmission, without "break break".)
Incidentally:
Blimey there's some pantie-twisting pedantry going on here.
Standard phraseology and required readbacks have been developed over decades for reasons of safety, and there's more than enough accident and incident history to make it evident that it's not "pantie-twisting pedantry" to object when a clear requirement is side-stepped for no clear reason;
especially when it results in confusion, as in this case.
Edit: (To add the relevant reference).
CAP413 says very clearly at para. 2.69:
CAP413 wrote:The ATS messages listed below are to be read back in full by the pilot/
driver. If a readback is not received the pilot/driver will be asked to do
so. Similarly, the pilot/ driver is expected to request that instructions are
repeated or clarified if any are not fully understood.

There appears to be no phraseology within CAP413 for an ATCO to use to inform the pilot that a particular readback is not required. Is there something like that within the MATS document set?
