Judges due to rule on legal challenge brought over Priti Patel bullying claims
The FDA union brought a judicial review over the PM deciding last year to go against the findings of his then adviser on ministerial standards.

Boris Johnson is due to discover the outcome of a High Court challenge over his decision to back Priti Patel following accusations of bullying.
The FDA union brought a judicial review over the Prime Minister deciding last year to go against the findings of his then adviser on ministerial standards in order to back the Home Secretary.
High Court judges are expected to deliver their ruling in the case on Monday.
In an investigation into Ms Patelās behaviour, published in November last year, Sir Alex Allan found she had not always treated civil servants with āconsideration and respectā.
He concluded: āHer approach on occasions has amounted to behaviour that can be described as bullying in terms of the impact felt by individuals. To that extent her behaviour has been in breach of the ministerial code, even if unintentionally.ā
Mr Johnson, the arbiter of the ministerial code, said the Home Secretary was āunawareā of the impact she had and he was āreassuredā she was āsorry for inadvertently upsetting those with whom she was workingā.
After āweighing up all the factorsā, he concluded the code had not been breached.
But at a hearing last month, lawyers for the FDA, which represents senior public servants, argued Mr Johnson āmisinterpretedā the term ābullyingā in the ministerial code when deciding if Ms Patelās treatment of civil servants breached its standards.
They alleged he made a āmisdirection of lawā in reaching his decision.
Lawyers for Mr Johnson argued that the FDAās claim was ānot justiciableā and that there had been āno error of lawā
They said the ministerial code ādoes not create or impose any legal duties on ministers or the Prime Ministerā, is ānot required by lawā and its contents ānot regulated by lawā.
The code was a āpolitical documentā and ānot about protecting the rights of civil servantsā who still have access āto all the employment law rightsā, the Prime Ministerās lawyer argued.
Sir Alex left his role in Downing Street after Mr Johnson contradicted his advice.
Following the publication of his report, Ms Patel issued an āunreserved, fulsome apologyā and said there were āno excusesā for what happened.
Lord Justice Lewis and Mrs Justice Steyn are due to hand down their judgment on Monday morning.
