If labour think the law is wrong or not in line with their party stance, then the remedy is to seek to change the law to change sex to self identified gender for all legislative purposes. Please can they stop with the surreptitious delays and obfuscation which is further destroying public faith in politics and damaging the country.
Let them campaign on that basis and guage public support. Let them be honest about the fact that any man may access women in changing rooms, toilets, prisons, hospital wards ( 33 rapes a week according to recent reports on NHS England wards). Honesty please.
