Should it be 'in strict confidence' or 'in strictest confidence'?

[DaisyMooSteiner]

I'd have personalyl said it should be either 'in strict confidence' or 'in the strictest confidence' but happy to be corrected!

Bumping for you.

I agree with Daisy

Surely it depends how strict the confidence is IYSWIM!

This really depends on what is laid down by the company. There should be a security policy stating what term is to be used, under what circumstances and what extra precautions need to be taken when it is used (e.g. allowed to be sent by e-mail or not, allowed to be sent by ordinary mail or not, how many envelopes needed etc..).

In the civil service the term used is "In strictest confidence"
