On Monday, Home Secretary Yvette Cooper announced those who cover up or fail to report child sexual abuse could face professional or criminal sanctions under a new offence to be introduced this year.

The proposal was one of 20 recommendations made by Prof Jay following her seven-year inquiry into child sexual abuse, which concluded in 2022.

Cooper said the change would be added to the Crime and Policing Bill this spring.

Alex Davies-Jones, the government’s minister for victims and violence against women and girls, said a date had not been fixed for when all 20 recommendations of the Jay Review will be implemented.

She told BBC Breakfast: “We have been in government for six months – the previous government had years to implement these recommendations and sat on their hands instead of actually acting.”

Maggie Oliver, a former Greater Manchester police detective who resigned in 2012 over poor handling of abuse cases in Rochdale, said the home secretary’s statement on child abuse was “a bit of a kneejerk reaction to international horror at what has happened in our country”.

The Conservatives’ shadow justice secretary Robert Jenrick has called for a national inquiry and said “what we’ve learnt more recently is the sheer scale of what is happening”.

“The Jay Review, for example, looked at six towns. We now suspect at least 50 towns have had grooming gangs of this kind,” he told BBC Breakfast.

“It’s right we have a full national inquiry so we can get to the truth, we can ensure the victims have justice, that we can try to prevent other vulnerable young girls from being in this position again, and the frankly cowardly officials and councillors who have covered this up can also be brought to justice.”

Asked whether the Conservatives had done enough to tackle the issue in government, Jenrick said “more needs to be done”.

He said: “I have long advocated going further than that and saying you should have a full-life sentence if you are a grooming gang perpetrator, so you never see the light of day, so you go to jail, you don’t step foot out on the streets of our country in 10 years or so, as is happening at the moment.

“This is one of the most appalling racially aggravated crimes in our country’s history. It must be taken more seriously by everyone.”
