Relatives of two men who died in Woodhill Prison have lost their High Court case over the rate of self-inflicted deaths at the jail.
Ian Brown, 44, hanged himself in his cell at the category A prison in Milton Keynes in July last year, while Daniel Dunkley, 35, died later the same month.
A total of 18 men have died at the jail since 2013 while seven men killed themselves just last year.
Mr Brown's mother and sister, Pearl Scarfe and Julie Barber, and Mr Dunkley's brother, Jamie Blyde, who is himself a prisoner, wanted the court to order Woodhill's governor and the Secretary of State for Justice to comply with the requirements of the Prison Service Instructions (PSIs).
They cover management of prisoners at risk of harm to self, to others and from others, early days in custody and medical emergency response codes.
On Tuesday, Lord Justice Irwin and Mr Justice Garnham rejected the judicial review claim which the governor and the Secretary of State for Justice said was "neither appropriate nor necessary".
