I repeat, if uniform has to be worn, this is next to useless
Why, in two parts - why do you think so? And why do you feel the need to repeat it?
I can confirm that "CCF Wednesday" still exists in Main Building. I think uniform all the time is long overdue for all personnel in London. In recent years I have travelled in uniform numerous times by both civair and train and it has never been an issue. In a previous life I was lucky enough to have to attend NATO meetings in a number of capitals/MODs and I was always the one incorrectly dressed in a suit rather than uniform.
