@dave30th I wonder if this presents an opportunity for you to get the letter (or an abbreviated version) published in the Times as a Letter to the Editor?
I think that's a good idea. Also @dave30th if you want more MPs to sign the letter, I'd be happy to try. They're normally very keen to sign things (eg Early Day Motions) as it's an easy way for them to do some virtue-signalling to their constituents. I'm pretty sure the one I was in contact with before the June debate would.
