How long can the speaker of the house of commons keep his job?

The Speaker of the House of Commons in the UK does not have a fixed term but typically serves for the duration of a Parliament, which can last up to five years. However, the Speaker can be re-elected at the beginning of each new Parliament. They may also resign or be removed by a vote of the House if they lose the confidence of its members. Ultimately, the Speaker's tenure depends on political circumstances and their ability to maintain support within the House.
