Apologies for raising this topic again. I started another thread as the last one descended into a discussion of people's bikes!
Steadily working my way through the 300+ pages of manual, I came across the Battery Maintenance instructions on pages 290-293. I strongly suggest that anyone planning on not using their car for a prolonged period, whether due to COVID or any other cause, should read those pages, as they cut across advice circulating on this forum and elsewhere. MG are quite explicit that not following their instructions will invalidate the battery warranty.
Reading the manual must take precedence over my interpretation but in essence:
That's it folks. Form your own opinion, but they are the people underwriting the battery warranty!

Reading the manual must take precedence over my interpretation but in essence:
- if you're storing the vehicle for a month or more, disconnect the 12V battery -ve terminal. It doesn't say whether this affetcs the keyless entry, so unless you know different, be sure you know how to enter the car with a key before doing this!
- a vehicle stored for a prolonged period must be charged at least once every 3 months. The manual doesn't specify to what level, but elsewhere states that a full equalisation charge of the HV battery is recommended at least once a month. The implication therefore is presumably that the three monthly charge should be an equalisation charge.
- At no point in prolonged storage should the HV battery level be allowed to drop below 50%
That's it folks. Form your own opinion, but they are the people underwriting the battery warranty!
