I just read the BMA briefing document from end to end only took a few minutes!
I'm afraid that I made the assumption that they knew what they were talking about.
Until today I had no idea or worry that there might be a time limit.
I'm pleased and heartened that you both received extended treatment on the basis of EHIC.
From what I've read the current withdrawal agreement will cover treatment for those abroad on B day in January.
Of course I believe Boris when he says he can deliver everything he promises despite all the evidence to the contrary
I stick to the point that our EHIC membership is a result of being an EU member.
Quite what Boris plans for future reciprocal deals is anyone's guess but whatever it is will only be a moment's effort for him and his crack team to negotiate.
