Mr Betts joined the council in February 1999 at a time when Hillingdon's social services department was on special measures for its services to children. Since then the department has made great progress in many areas, including being taken off special measures earlier this year and the recent praise for the department in a government report, in particular for its services to children.
Hillingdon's chairman of social services, David Simmonds said: 'While I will be sorry to lose Graeme's day to day input in the social services department, I am delighted that he is staying in Hillingdon. In working closely with the primary care trust he has already helped to deliver service improvements and we look forward to working with him in his new post. Staff and councillors know that the strong management team that Graeme has put in place will help the council to continue modernising and improving social services for the borough.'
'Hillingdon LBC and the PCT already closely co-operate in many areas where services to users are delivered jointly', he added.
