At a local level, it is the responsibility of primary care trusts (PCTs) working with local authorities to co-ordinate work to tackle childhood obesity. PCT plans, developed alongside local authority Children and Young People's Plans, will feed into local area agreements agreed with the Government offices. Local areas will develop and implement their own initiatives based on local needs and circumstances.
