The Conservatives have pledged to sweep away bureaucracy to free up frontline social workers to concentrate on protecting vulnerable children.
Shadow children's minister Tim Loughton announced that eminent academic Professor Eileen Munro would chair an expert panel on cutting red tape in the profession.
Mr Loughton is due to give the keynote speech at an event to mark the 10th anniversary of Victoria Climbie's murder in Haringey, north London, in February 2000.
In a new Tory policy paper on social work, he warned that this and later tragedies - including the death of Baby P (Peter Connelly) in Haringey in 2007 and the sadistic torture carried out by two young brothers in Edlington, South Yorkshire, last year - showed the system was not fixed.
"It is not scaremongering to face up to the reality that despite all the investment, all the legislation and all the hard work of professionals at the sharp end, the child protection system in our country is still not working properly," he said.
Mr Loughton suggested that the major new child protection policies introduced after Victoria's death might actually have made the situation worse.
He said: "It is not the quantity of legislation and regulation that is at fault but rather the quality, content and direction.
"Indeed there is now a growing body of opinion that many of the structural changes that we have seen, and particularly the constant upheaval and drain on resources and morale, are actually undermining the effectiveness of child protection systems."
The Conservatives have pledged to help experienced social workers stay at the front line, allow social workers to run their own practices like GPs, and publish serious case reviews into the worst examples of child abuse in full.
Mr Loughton said: "Anyone can see that social workers should not be spending 80% of their time on desk work. We will send in the experts to sweep away unnecessary bureaucracy."
