Part 1: Sanctions regulations Chapter 1: Power to make sanctions regulations Section 4: Immigration sanctions
Section 4 provides for travel bans. Those who are subject to travel bans would be "excluded persons" within the meaning of section 8B of the Immigration Act 1971. Section 8B of the Immigration Act 1971 provides that an excluded person must be refused leave to enter or leave to remain in the UK, any leave the person holds is cancelled, and any exemption from immigration control no longer applies.
	Travel bans are used to restrict the movement of designated persons and those associated with regimes or groups, including terrorist groups, whose behaviour is considered unacceptable by the international community. Currently, section 8B of the Immigration Act 1971 provides for an international travel ban made either by the UN Security Council or the EU to be enforceable by the UK. Unless an exemption applies, a person who is subject to a travel ban is prevented from entering the UK.
	The Act (see Schedule 3) amends section 8B of the Immigration Act 1971 to accommodate UK autonomous sanctions regimes, as well as making provision for retained EU travel bans after the UK has left the EU.
