In the current situation we're talking about a young pregnant British woman who wants to return to Britain. She should be allowed to return and helped to do so as far as is practical. The same would go for any British citizen regardless of gender or ethnicity or political orientation, although the pergnacy clearly makes the situation more urgent as would a serious health condition .
As far as I can gather she has no other nationality so there is no other state she could move to. There's no indication that she is being accused of any crime in the location she is currently located. If she were she should as far as practical be offered consular support. Wherever she is she has the right to a fair trial, again it is the British states duty to try to ensure this happens.
Its all moot anyway because you can't give UK consular service in a country where there are no UK consular services. But you know this anyway.
