A senior Department of Health official has been appointed as England's first children's commissioner.

Professor Al Aynsley-Green was unveiled on Wednesday in the coveted watchdog's role, ending month's of speculation as to who the government would pick.

Arts minister Estelle Morris and Labour MP Hilton Dawson had both been tipped for the job but the selection panel, which uniquely included young people, went for a more independent choice.

Previously national clinical director for children in the health ministry, the paediatrician will immediately take up the post created by parliament last year.

The position is intended to act as a voice for young people as well as overseeing their care and investigating cases of wrongdoing.

It follows the establishment of similar roles in Scotland, Wales and Northern Ireland.

Education secretary Ruth Kelly said: "I am delighted that Al Aynsley-Green will be our first children's commissioner in England.

"His appointment will strengthen the voice of children and young people, giving them their very own representative to take forward the matters close to their hearts."

Professor Aynsley-Green added: "The creation of a children's commissioner affirms the importance of children and young people and their central role in society.

"I am honoured to be taking up this position and look forward to working with children and young people, and organisations dedicated to them, to make sure that their opinions count.

"I will be drawing on my experience of working with children and young people to help ensure that those with the power to improve children's lives do live up to their responsibilities.

"I want all children and young people to know that they can approach me to discuss any matter that affects them, knowing that I will value their opinion.

"Children and young people have often been ignored in public life and I am dedicating my role to setting that straight."
