The plans have faced some criticism.
All four upper tier local authorities in Sussex and Surrey have stated their opposition to the proposed Sussex and Surrey ICB.
They believe it is contrary to mayoral guidelines, will not enable meaningful and effective neighbourhood healthcare to be delivered, and could lead to even greater local NHS cuts.
Roy Lilley, health analyst and former NHS chief executive, said: “You can’t save that kind of money without stopping doing things; employing people, helping people or who they work for.
“This is a difficult time and there are no popular decisions to make.”
