I seem to remember that there was quite a hiatus after the 2016 about the failure of postal votes to arrive on time. My daughter and a number of her friends registered but never received their voting forms. The postal service in our area, the south west, is worse than I ever remember - post arrives late or never and items are damaged. A postal voting option requires a sound postal system.
