The document must include the principal threats to border security, as viewed by the Commander at the time the document is issued. The document must also set out the strategic priorities to which partner authorities should have regard in exercising their functions in relation to any of the principal threats identified in the strategic priority document.
	In exercising its functions in relation to threats to border security, a partner authority must have regard to the strategic priority document (subsection (3)).

	Subsection (5) sets out definitions of "border security", "partner authority" and "public authority". Subsection (6) also outlines the exclusion from the definition of "partner authority" (and therefore in relation to obligations on partner authorities) for (a) the Security Service, (b) the Secret Intelligence Service, and (c) the Government Communications Headquarters. (See also subsections (3) and (4) of section 5 in relation to those bodies.)

	Subsection (8) identifies the circumstances where the passage, conveyance, organisation or preparation as referred to in subsection (7): (a) constitutes an offence under the law of any part of the United Kingdom; (b) creates a risk of the commission of an offence under the law of any part of the United Kingdom; or (c) threatens harm of any kind to persons or property in the United Kingdom.
	Subsection (9) provides that, for the purpose of this Act, threats to border security do not include threats relating to a customs revenue matter as defined in section 7(2) of the Borders, Citizenship and Immigration Act 2009.
