David Cameron chose to focus on a report into child abuse in Doncaster at today's prime minister's questions.
In a subdued series of exchanges with Gordon Brown, he called for the report to be published in full.
Cameron began by saying "we can be proud of the British response" to the earthquake in Haiti.
He asked how in future the initial rescue effort can be more efficient.
Brown said the UN should have a new dedicated reconsrtuction agency, ready to deal with disasters.
He said that British firemen are in Haiti helping with rescue efforts and British troops will help unload supplies.
The UK has agreed to help rebuild the civil government.
Cameron said Haiti will need external help for many years to come and asked what the UK will do to support joint structures with UN and Haiti government.
The prime minister said Canada is hosting a funding conference and the EU has already offered 400m euros.
He told the House he has talked to the UN secretary general and US president Barack Obama and agreed that it is important the Haiti government is seen as legitimate.
He said lessons will be learnt from the disaster and added that the UK has a civilian team "ready to go" where stabilisation is needed.
Cameron turned to the case of two children who were tortured and abused last year by two boys who were well-known to Doncaster social services.
The boys, then aged 10 and 11, tortured, sexually humiliated and beat their victimes, who were nine and 11.
Cameron said the serious case review will be produced this week but only a summary will be published.
"Why so many warning signs were missed?" he asked.
Brown said the matter is before the courts, "but we all agree about the seriousness of this case".
He added he does not want Britain to be defined by this sort of behaviour.
The serious case review was launched to learn lessons and in the interests of people being able to tell the truth, only the summary will be published.
Brown said there have been flaws in social services and Doncaster is already under special measures.
He said we cannot draw conclusions until we see the review.
Cameron called for the report to be published in full.
Seven children died in Doncaster between 2004 and 2009.
"Why did so much go wrong for so wrong?" he asked.
Cameron said there have already been five serious case reviews and they did not lead to correct action being taken.
The prime minister said Lord Laming's recommendations are being implemented.
"I do not want to prejudge the review," he said.
To protect the identity of the children, it will not be published in full.
"The problem in Doncaster was action was taken but it was the wrong action," he said.
Cameron said the argument is tipping in favour of full publication and claimed the summary of the review of the Baby P case "was not worth the paper it was written on".
Brown said he is "sorry" the leader of the opposition keeps "moving ahead on this point".
He said "every voluntary organisation and professional I know" agrees that only the summary should be published to protect the anonymity of the children and allow people can give honest accounts of what happened.
The Tories "stand isolated from experts on this," he said.
Cameron claimed "we are not going to learn the lessons" unless the full review is published.
He said there are cases where the review was "inadequate" and according to the BBC the Doncaster serious case review does not match the summary.
Brown pointed out that the court case is not yet complete and the report has been leaked, not published.
He said he has taken the advice of Lord Laming and many children's societes on the matter.
Children must be able to tell the inquiry what they think went wrong and do it anonymously, he added.
Brown said Cameron "asked me a series of detailed questions when he has not even read the report."
Nick Clegg returned to the acquisition of Cadbury by Kraft.
He said that Lord Mandelson had promised to mount "huge opposition" to the takeover, but now it appeared that the Royal Bank of Scotland was lending money to the American firm in order to fund the move.
The Liberal Democrat leader said it was wrong that a largely state owned bank was funding a take over that could lead to job losses.
"RBS wants to lend money to a multinational that wants to cut jobs," he said.
But the prime minister said the government should not dictate to the bank who it did and did not lend money to.
"His liberal principles seem to have gone to the wall," he said.
Brown said that there was no government that had done more to protect jobs.
"He has got nothing to offer the debate on the economy at all," he added.
