EDM
Thud
My MP gave me the same reply - that he doesn’t “do” EDMs. Your post prompted me to check how many he had signed - about 135! So I will write to him again.
To give him his due, however, he did write to Adam Ingram in support of the campaign, but not surprisingly received the standard reply ending with “The Government retains every confidence in the judgement of the reviewing officers, but remains prepared to review its position should any compelling new factual evidence be brought”. So no change there, then.
