MPs step down from their constituency all the time with regulations existing which dictate how a new MP is selected.

While the loss of an MP before an election is common, how new ones are selected outside of a General Election is not known by everyone.

In this article, we will answer some of the most commonly asked questions when it comes to an MP stepping down.

When an MP steps down from representing their constituency in the House of Commons, a by-election is usually held to select a new representative.

By-elections are elections that take place outside of General Elections and during parliamentary terms.

How are MP candidates selected by political parties?

While those wanting to run as an MP can do so either as an independent or as a member of a political party, the latter is more common.

To be nominated to stand for a political party, you normally have to have been a member for a long period of time (varying from three months to a year).

Applicants are then sent forms and assessments containing questions about their lives, political experience and careers.

A centrally approved list of candidates is then put to the local members by the nationwide party for selection.

Who is allowed to run as an MP?

Nearly anyone can put themselves forward as an MP with some exceptions applying, according to the BBC.

Firstly, candidates must be aged 18 and over and be a British citizen or a qualifying citizen of the Commonwealth or the Republic of Ireland who is resident in the United Kingdom.

How long does it take for by-elections to be held after an MP resigns?

According to the Parliament website, in order for a by-election to be held, the Chief Whip must start by 'moving the writ', a motion requesting that the Speaker of the House issues a warrant for a writ to the Clerk of the Crown to allow an election to proceed.

A new writ is usually issued within three months of the vacancy being made.

A by-election is usually held between 21 and 27 working days after the issuing of the writ.

How much do MPs earn?

As of April 2023, MPs in the House of Commons earn around £86,584 a year after the basic annual salary was raised.
