Oath of Allegiance
After election to the Commons an MP must swear an Oath of Allegiance before taking their seat. While holding a copy of the New Testament (or, in the case of a Jew or Muslim, the Old Testament or the Koran) a Member swears: "I…..swear by Almighty God that I will be faithful and bear true allegiance to Her Majesty Queen Elizabeth, her heirs and successors, according to law. So help me God." Members who object to oath swearing may make a Solemn Affirmation instead.

Officials' Box
The Officials' Box is a row of seats in the House of Commons to the right of the Speaker, facing into the Chamber that is reserved for civil servants. They sit there to advise Ministers during debates. In the Lords, there are similar arrangements: government officials sit to the right of the Lord Chancellor and on the opposite side is a box where Clerks and other officials of the House of Lords sit.

Ombudsman
The Parliamentary Commissioner for Administration, or Parliamentary Ombudsman, investigates complaints from members of the public about Government Departments. The ombudsman has wide powers to obtain evidence from Government Departments and make recommendations about the cases he or she hears. Cases must be referred to the Ombudsman by an MP.

Opposition
The Opposition are the political parties other than the largest or Government party. They are called the Opposition because they sit on the benches opposite the Government in the House of Commons and House of Lords Chambers. The largest of the Opposition parties is known as Her Majesty's Opposition. The role of the Official Opposition is to question and scrutinise the work of Government. The Opposition often votes against the Government. In a sense the Official Opposition is the "Government in waiting".

Opposition Days
Opposition days are days allocated in each session for the discussion of subjects chosen by the Opposition. The Opposition generally use them to raise questions of policy and administration.

Order Confirmation Bills
Order Confirmation Bills are Bills that apply to Scotland only and stem from the Private Legislation Procedure Act of 1936. It was intended to extend the Act to Wales and Ireland but this was never done. The object of the Act was to transfer the initial steps of the Scottish legislation to Scotland. The Secretary of State for Scotland issues a Provisional Order that has to be confirmed by Parliament. Order Confirmation Bills follow the pattern of Private Bills as they pass through Parliament.

Order of Business
The Order of Business lists business set down for each day's sitting in the House of Commons: it is in effect the House's agenda. It follows the normal order in which business is conducted, although not all items taken on the floor of the House require notification in the Order of Business. The following headings are used to describe the main categories of business: Prayers, end of day Adjournment Debates , Private Business, Questions for Oral Answer, Urgent Questions and Ministerial Statements , Preliminary Business, Main business, Committee Meetings, Written Questions tabled on previous day for answer today, Standing Committee Notices, Memoranda.

Orders in Council
Orders in Council are used when an ordinary Statutory Instrument would be inappropriate, such as for transferring responsibilities between Government Departments. Orders in Council are issued "by and with the advice of Her Majesty's Privy Council". Orders in Council were used to transfer the powers from Ministers of the UK government to those of devolved assemblies.

Outlawries Bill
The Outlawries Bill is read at the beginning of every new session of Parliament, when the Commons return to their own chamber to debate the Queen’s Speech. The reading of the Outlawries Bill is a tradition which preserves the right of the Commons to debate a subject of their own choosing before they debate the subjects raised by the Queen's Speech. In practice there is no debate and the Outlawries Bill is read out as a formality. The text has remained the same since Victorian times, but the first recorded instance of the House reading such a Bill before any other business dates back to 1558.
