The tri-borough children’s service based in west London will work with the government to help turn around failing services.

It comes after Prime Minister David Cameron promised radical reforms which meant poorly performing children’s services must improve - or they will be taken over.

He singled out six local authorities with exemplary services which will work with the government to turn children’s services in other councils around.

Among the six is the joint-venture children service for Hammersmith and Fulham , Kensington and Chelsea and Westminster boroughs.

The news was welcomed by Westminster City Council leader Philippa Roe, who praised the work in the boroughs. She said: “Westminster is extremely proud that our exemplary children’s services have been recognised by the government. Working with Kensington and Chelsea and Hammersmith and Fulham has allowed us to provide an innovative approach which puts the safety and wellbeing of children at the heart of the service.

“I have no doubt that our children’s services will continue to be a massive success for years to come and we look forward to working with the education secretary to implement and support the new proposals.”

Other ‘exemplary’ councils chosen to help are Richmond and Kingston, North Yorkshire, Hampshire, Leeds, Durham.

It is now expected that Secretary of State for Education, Nicky Morgan will chair a round table of the council leaders who have been identified as the highest performing next year.
