The database is updated in near real time as national and by-elections take place. Covering all nationally elected and appointed Members across the House of Commons, House of Lords and Devolved Governments. The data includes parliamentary contact information, political party and gender as well as recording posts for party leaders and cabinet membership positions.
Aside from Lords, Members are elected - typically every 5 years - to cover a political area known as a Constituency. Members are also typically aligned with, members of and promote themselves as part of political parties.
Members of Parliament (MPs) - Elected across the UK and forming the membership of the House of Commons.
Lords - Membership to the House of Lords is primarily by appointment, though there are a small number of hereditary members. Appointment comes via the King through recommendation from the Prime Minister or Appointments Commission. The purpose of the Lords is to scrutinise the passing of laws/legislation proposed by the Commons and have the ability to make suggestions or even stop legislation being passed.
Devolved Government membership with representatives elected to regions and devolved constituencies. The countries and official titles being:
Scotland - Members of Scottish Parliament (MSPs)
Wales - Assembly Members (AMs)
Northern Ireland - Members of the Legislative Assembly (MLAs)
Following national elections, the party gaining the majority of seats (or multiple parties in the instance of a coalition) effectively run the Government (and become known as "The Government") they are headed by the leader of the party/the Prime Minister or First Minister in the case of a devolved Government. The other parties then take the position, through their members, of supporting or opposing the Government of the day in relation to individual issues and passing of laws, with the largest minority party being known as ‘The Opposition’
In the Commons, some of these MPs are part of what’s known as the Cabinet or Front Bench (membership is determined by the Prime Minister); responsible for Government Departments (these are known as Ministerial Departments it’s worth noting there are also ‘Non Ministerial Departments’ for example HMRC which are run by Civil Servants and are intended to be beyond Political control and are therefore not headed up by an MP). The MP (or ‘Minister’) that heads up a Department
takes on the political and strategic responsibility for the running of their department.
