How long does it take for a new House of Commons to get fully up and running?

19 Apr 2020
Queen Elizabeth Tower, UK Houses of Parliament

There will be gaps in a new House of Commons' scrutiny of the government and engagement with the public until the events required at the start of a Parliament have taken place and all the necessary institutions and processes have been re-established. The length of time taken over procedures at the start of a Parliament therefore matters.

Our 'Back to Business' collection of procedural guides provides information about the key events and procedures at the start of a new Parliament.

The chart below shows the timings of key House of Commons events at the start of the 2010, 2015, 2017 and 2019 Parliaments, in terms of sitting days.

Information about converting sitting days to calendar days can be found below the chart. {: .small }

The sitting days shown on the chart can be roughly converted to calendar days by bearing in mind that the House of Commons normally sits for four days per calendar week, and – most importantly – by factoring-in the placing of the relevant sitting day relative to the House's recesses (which are shown on the lower rows of the chart), especially the long summer recess.

For example, the new House of Commons' 30th sitting day fell less than two months after the start of the Parliament in 2010 and 2015 (because it preceded the summer recess), but over two months afterwards in 2019-20, and nearly four months afterwards in 2017; in the latter two cases, it fell after two recesses.

In 2020, House of Commons calendar timings were affected by the fact that between the Easter and Whitsun recesses the House sat for only three days per week, owing to the restrictions on proceedings arising from the Coronavirus crisis.

Precise dates for most House of Commons events can be found via House of Commons Votes and Proceedings (each daily edition of which includes the sitting-day number at top left). Further information, where needed, can be found in House of Commons Hansard and news items on the House of Commons website.

News / Jury trials under threat? The Courts and Tribunals Bill explained - Parliament Matters podcast, Episode 136

Plans to restrict the right to a jury trial have cleared their Second Reading in the Commons, but the proposals in the Courts and Tribunals Bill face growing resistance, including from Labour rebels. We discuss the legal and constitutional implications with barrister Lord Macdonald of River Glaven, examining what the reforms could mean for defendants’ rights and the criminal courts system. We also assess the passage of legislation removing hereditary Peers from Parliament, and the late compromise that eased opposition in the House of Lords. Meanwhile Sir Lindsay Hoyle clashes with the Chief Whip over delays in the division lobby, and newly released papers on Peter Mandelson’s Washington appointment raise fresh political questions.

Briefings / Last-minute powers and limited scrutiny: Parliament and the risks of consigning online safety law to delegated legislation

Two late-stage government amendments to the Crime and Policing Bill and the Children’s Wellbeing and Schools Bill would grant Ministers significant powers to reshape key parts of the Online Safety Act through delegated legislation. While the policy goals may attract support, the method raises serious constitutional concerns about parliamentary scrutiny and accountability. Using these amendments as a case study, this briefing explores the risks of relying on regulations to make policy and explains how the Hansard Society’s proposed reforms to the delegated legislation scrutiny system could better balance governmental flexibility with democratic oversight.

News / Is the assisted dying bill being filibustered? - Parliament Matters podcast, Episode 135

Debate over the Terminally Ill Adults (End of Life) Bill has been so slow in the House of Lords that opponents of the Bill are accused of deliberately running down the clock. Conservative Peer Lord Harper rejects claims of filibustering, arguing that Peers are undertaking necessary scrutiny of a flawed and complex bill. He contends the legislation lacks adequate safeguards and was unsuited to the Private Member’s Bill process and discusses whether MPs might attempt to revive it in a future parliamentary Session.
