Re: despite the fact there's less than a year
Actually everything needs finalised by October 2018, about 6 months, less holidays.
Yet none of the difficult issues have any UK proposals other than fantasy. The EU is waiting for workable proposals from the UK. Brexit is a UK decision.
Scotland, N.I., London, City of London, NHS, Universities, fruit pickers, Ireland etc are not very happy about the total lack of research (apparently) and decisions what to do before calling referendum or invoking Article 50. It seems the UK cabinet can't agree what Brexit is or how to achieve totally conflicting aims.
This domain thing is a minor issue, easily solved compared to the other unresolved issues.
