The Government has threatened Birmingham's under-fire childcare agencies with further action unless it sees rapid improvements in services.

Commenting on the findings of the report into Keanu Williams's murder , Edward Timpson, the minister for children and families, said: "This is an awful case and the serious case review (SCR) shows that improvements are urgently needed."

Birmingham City Council's child safeguarding procedures , which were judged inadequate in June 2010, are due to be reviewed by Ofsted next month.

The city's children's services department was also served with an improvement notice by the Government in September 2010 after a serious of high-profile child deaths, including the starvation of seven-year-old Khyra Ishaq in 2008.

In a statement, Mr Timpson said: "Birmingham's problems are complex and we're taking action to secure properly embedded and sustained improvement to children's social care.

"Special performance measures are in place and I have issued the council with a final warning - Ofsted will return to Birmingham this autumn to determine what progress has been made.

"There is no quick fix, however I have been very clear with Birmingham that unless I see rapid improvement further action will follow.

"The increasing number of SCRs being published nationally is beginning to give us a deeper and clearer understanding of what goes wrong, and why, when child protection services fail."

Perry Barr MP Khalid Mahmood said he was fed-up of hearing the " same old story " coming from the city’s child protection agencies.

He said: “Here we are again with another damning serious case review wondering when things are going to change and when lessons will be learned.

“The city council has repeatedly failed to make the necessary changes and support staff.

"Keanu died more than two years ago but today we have 20 per cent of social work jobs not filled and many more staff off sick or with stress.

‘‘The problems go right through the department, Something has to change.”
