Baby P's "horrifying death could and should have been prevented", a second serious case review has found.

Doctors, lawyers, police and social workers should have been able to stop the situation "in its tracks at the first serious incident", the executive summary of the report said.

Even after the boy, who can now be named as Peter, was put under a child protection plan, his case was regarded as routine "with injuries expected as a matter of course".

Agencies were "lacking urgency", "lacking thoroughness" and "insufficiently challenging to the parent".

The review, carried out by Haringey Local Safeguarding Children Board, found that agencies "did not exercise a strong enough sense of challenge" when dealing with Baby Peter's mother and their outlook was "completely inadequate" to meet the challenges of the case.

The review was commissioned by Children's Secretary Ed Balls after Peter's death, because of concerns over the conclusions of the first review.

The review concluded that Peter "deserved better from the services that were there to protect him".

It found that agencies would only have been willing to move him if the injuries he suffered were found to be "non-accidental beyond all reasonable doubt".

"When such injuries did come they were catastrophic, and he died of them," the review found.

"The panel deeply regrets the responses of the services were not sufficiently effective in protecting him."
