A national campaign carrying the symbol of a red triangle will be rolled out across the UK to mark the International Day of Zero Tolerance for Female Genital Mutilation.

The National Police Chiefs’ Council has partnered with the Freedom charity to encourage people to provide the police with information that can help detect and prevent FGM in the UK and abroad.

Commander Mak Chishty, the police national lead on “honour”-based violence, has written to every police force in the country reminding them that while progress has been made, there is yet to be a successful prosecution for FGM.

He wrote: “This is a particular area of political and public scrutiny and I would urge each force to maximise every opportunity to demonstrate that we as a service are doing everything that is possible to combat FGM.”

His letter also cited a prevalence study published in July 2015 by City University and Equality Now, the human rights group, which showed that no local authority in the UK was unaffected by FGM.

Chishty told the Guardian: “We are raising awareness that FGM is a crime and that anybody involved in the process – from turning a blind eye to the act of cutting – commits a criminal offence. This is form of child abuse and violence against women and girls.”

More than 13,000 posters promoting the Red Triangle initiative have been distributed to police forces to display inside police buildings and within appropriate community settings.

Police leads have been asked to evaluate the campaign’s impact by monitoring any increased reporting, receipt of intelligence or new engagement opportunities.

Aneeta Prem, a writer and the founder of Freedom, has written a novel warning about FGM, called Cut Flowers, that is being distributed to schoolchildren to raise awareness of the illegal practice.

She said: “Over 200 million women and girls have gone through the horrors of FGM and we know that girls are being cut here in the UK. Unofficial figures estimate that 137,000 girls and women in Britain are affected.

“Through education we can stop FGM in a generation. Through teaching we can explain the long-term health dangers and dispel the myths that have kept this barbaric practice alive. The help of boys as well as girls is needed to change opinions.”

She added: “We are asking that people wear the red triangle badge to mark the International Day of Zero Tolerance to FGM.”

A 25-year-old from Somalia who suffered FGM and now lives in London said: “I was cut when I was five years old. I still feel pain and relive that moment every day. I completely support the Red Triangle campaign and hope it will encourage girls to ask for help.”

FGM protection orders intended to safeguard girls at risk came into effect in the UK in July 2015. The latest figures from the Ministry of Justice showed 97 applications and 79 orders had been made up to the end of September 2016.

The home secretary, Amber Rudd, said the government was taking “world-leading action” to tackle FGM by strengthening the law to improve protection for those at risk and by removing barriers to prosecution.

She said: “This government has introduced FGM protection orders, a new offence of failing to protect a girl from FGM, a mandatory reporting duty for frontline professionals, new guidance for the police, and lifelong anonymity for victims to encourage them to come forward.

“We are sending a clear message that FGM will not be tolerated, and as part of this I am determined to see the country’s first successful prosecution for FGM.”

The Red Triangle campaign, which will run until International Women’s Day on 8 March, will officially launch at Haverstock school in Camden, north London, on Monday. Baroness Featherstone has called on Theresa May and Justine Greening to ‘use your power’ to fight FGM. In a video appeal to mark zero tolerance day the Lib Dem peer asks that prime minister and the education secretary make teaching of FGM compulsory in all UK schools.

Greening and May lobbied hard under David Cameron for more funding and education on FGM.

“You both have a proud record on this issue but… we agreed it should be taught in schools, whether by teachers or community volunteers,” Featherstone writes in an open letter.

“If it is not, then we are not safeguarding our children. You are both now in positions to finally make this happen. You have the power. I am asking you to use it.”
