I understand that the unions have asked the government for the evidence that they have used to determine the safety of schools (I hope that this is right, please advise if not). I've read (on mumsnet) that there will be a result of some sort of the legal challenge tomorrow. Can anyone explain please what is likely to come from this and what time to expect the result? I've tried to google it and have looked on unions website but you have to log into the website and the google search is bringing up mostly yesterday's news but without the detail. I'd appreciate any info please, many thanks
