The new Secretary of State for Justice and Lord Chancellor Alex Chalk KC MP speaks to Joshua Rozenberg. How does he respond to criticisms levelled at the reforms of the Parole Board proposed in the Victims and Prisoners Bill? And how does he reconcile his wish to "provide individuals with the due process which is the hallmark of our legal system" with some aspects of the Home Office's Illegal Migration Bill, that aims to stop people crossing to the UK in small boats? Mr Chalk also speaks about new measures to protect investigative journalists from malicious libel actions, and confirms that the new Lord Chief Justice will be a woman, for the first time in a thousand years.

Most of the senior judges in England and Wales are male, white, middle-aged and former barristers. The new head of the Judicial Appointments Commission, Helen Pitcher, in her first broadcast interview, tells Joshua that diversity is very important and admits its an issue in the judiciary. So how will she increase it? We hear about projects and research to help remove barriers and ensure senior judges reflect the society they serve.

What is it like to do your job after a diagnosis of Parkinson's? The condition affects people differently, but many have a tremor, fatigue, reduced mobility in their arms, legs, or both, and some can have depression. Joshua meets a High Court judge, Sir Nicholas Mostyn, to find out how he has been able to carry on working despite the condition. What are employees' rights in this case? And what is it like for those in other lines of work? We also hear from a nurse with Parkinson's on how she does it.
