Section 1: Reports of the Boundary Commissions
Section 1 makes amendments to section 3 of the Parliamentary Constituencies Act 1986 ("the 1986 Act") to make changes to the timing and frequency of reviews of parliamentary constituencies and the arrangements for the submission of boundary reports.
	Subsection (2) amends section 3(1) of the 1986 Act to require the Boundary Commissions to submit boundary reports to the Speaker of the House of Commons ("the Speaker"), instead of the Secretary of State or Minister for the Cabinet Office.
	Subsection (3) amends section 3(2) of the 1986 Act and requires the Boundary Commissions to carry out a review of parliamentary constituencies and submit reports to the Speaker as follows:
before 1 July 2023,
before 1 October 2031, and
before 1 October of every eighth year after that.
	This replaces the current requirement for the Boundary Commissions to report every 5 years.
	Subsection (4) inserts the following subsections into section 3 of the 1986 Act:
subsection (2ZA) requires a Boundary Commission to send a copy of its report to the Secretary of State or the Minister for the Cabinet Office at the same time as it is submitted to the Speaker;
subsection (2ZB) provides that once the Speaker has received the report, the Speaker must lay the report before Parliament;
subsection (2ZC) requires the Boundary Commission to publish the report as soon as reasonably practicable after it has been laid before Parliament.
	Subsection (5) amends section 3(2B)(a) of the 1986 Act which changes the timing for which progress reports are submitted to the Speaker to the "relevant January". Subsection (6) inserts new subsection (2BA) which defines "relevant January" as meaning January 2022 for progress reports relating to the review reports due to be submitted before 1 July 2023, and in the case of all subsequent review reports the January that begins one year and nine months before the date a report is due to be submitted.
	Subsection (7) removes section 3(5) to (5C) of the 1986 Act as a consequence of other changes made by the Act. Section 3(5) of the 1986 Act concerns the laying of boundary reports before Parliament and is no longer required as a result of new section 3(2ZB). The matters currently provided for in section 3(5A) to (5C) of the 1986 Act have been replaced by provisions made by sections 2 and 3 of the Act concerning Orders in Council giving effect to boundary reports.
