“(1) The Chancellor of the Exchequer must review the effects on the provisions of this Act of migration in each of the scenarios in subsection (2) and lay a report of that review before the House of Commons within one month of the passing of this Act.
(2) Those scenarios are that—
(a) the UK leaves the EU withdrawal transition period without a negotiated future trade agreement,
(b) the UK leaves the EU withdrawal transition period following a negotiated future trade agreement, and remains in the single market and customs union, and
(c) the UK leaves the EU withdrawal transition period following a negotiated trade agreement, and does not remain in the single market and customs union.
(3) In respect of each of those scenarios the review must consider separately the effects of—
(a) migration by EU nationals, and
(b) migration by non-EU nationals.
(4) In respect of each of those scenarios the review must consider separately the effects on the measures in each part of the United Kingdom and each region of England.
(5) In this section—
‘parts of the United Kingdom’ means—
(c) Wales, and
(d) Northern Ireland;
and ‘regions of England’ has the same meaning as that used by the Office for National Statistics.”—
This new clause would require a Government review of the effects on measures in the Bill of certain changes in migration levels.
