Each integrated care board may arrange for the provision of such services or facilities as it considers appropriate for the purposes of the health service that relate to securing improvement—
in the physical and mental health of the people for whom it has responsibility, or
in the prevention, diagnosis and treatment of illness in those people.
For the purposes of this section an integrated care board has responsibility for—
the group of people for whom it has core responsibility (see section 14Z31), and
such other people as may be prescribed (whether generally or in relation to a prescribed service or facility).
An integrated care board may not arrange for the provision of a service or facility under subsection (1) if NHS England has a duty to arrange for its provision by virtue of section 3B or 4.
In exercising its functions under this section, an integrated care board must act consistently with—
the discharge by the Secretary of State and NHS England of their duty under section 1(1) (duty to promote a comprehensive health service), and
the objectives and requirements for the time being specified in the mandate published under section 13A.
