Justice Secretary Chris Grayling has told ITV News it is 'right and proper' for the Government to ensure tragic deaths like that of Hamzah Khan never happen again.
Earlier, children's minister Edward Timpson said a serious case review failed to address key questions.
He expressed his 'deep concerns' over the review's findings that the four year old's death could not have been predicted.
Mr Grayling supported his colleague's stand and said it was important no stone was left unturned in finding out what happened.
Local MP George Galloway gives his reaction to the publication of today's report
It is always easy to apply hindsight after Hamzah Khan's death and in such a tragedy easy too to apportion blame.
