A pledge to challenge mental health stigma and promote wellbeing among officers has been made by the Metropolitan Police.
The Mind Blue Light 'Time to Change' Pledge was signed by Commissioner Sir Bernard Hogan-Howe to help keep their staff well enough whilst they carry out their job.
Understanding mental health and offering support and wellbeing advice within the organisation has been prioritised.
Sir Bernard said: "With one in four people suffering from mental illness - mental health issues can affect any of us at any time.
"Time to Change is a very positive initiative, which the Met is proud to be a part of.
"Signing the pledge underlines the Met's commitment to ensuring we challenge stigma associated with mental ill health, look after our officers' and staff wellbeing and welfare and provide the right support when they most need it."
It is one of over 300 employers across the country working to tackle mental health.
The signing coincides with 'Time to Talk Day', aimed at encouraging as many people and organisations across England to get talking.
Paul Farmer, chief executive of Mind, said: "Not only are many of our blue light personnel struggling with their mental health, but they're less likely to seek support or have time off sick than the general workforce.
"Good mental health should be a priority in any workplace but it is especially important that people exposed to traumatic of life-threatening situations - such as those working within the police, ambulance, fire and search and rescue services - receive appropriate support."
Commander Christine Jones, the Met and national lead for mental health and policing, said the policing environment can be a traumatic environment for officers and the force "seem less able to assess our own ongoing mental good health".
