Claudia Hammond talks to Chris French, Professor of Psychology at Goldsmiths University of London about conspiracy theories. Are they really harmless, and why is it that some people believe in them but not others? She meets two newly elected MPs, Naz Shah from Bradford West and Johnny Mercer from Plymouth, to discuss their plans for mental health and how to get things done as a new back bench MP. Also in the programme, Claudia visits Raw Sounds' studio in Brixton, South London - an innovative music project where people with mental health problems can make and perform music with the help of professional music producers.
