The College of Policing and the National Association of Muslim Police have worked together to produce a guidance document on prayer provisions. Chaplains can log in the forum to view it.

"Prayer is one of five pillars within Islam and forms part of daily life for Muslims. In collaboration with NAMP we have produced a guidance document for adjustments to facilitate prayer provisions within the workplace. This guide will help police forces meet the religious needs of Muslims and improve faith inclusivity."
Alexander Gent, Chair, NAMP
