With all the controversy surrounding Boris Johnson’s extended prorogation, I’ve been asked if I think the practice of proroguing Parliament is likely to be abolished in the not-too-distant future. However, outright abolition seems unlikely.
Until now, prorogation has been a routine bit of parliamentary procedure, and it’s necessary to pave the way for the Queen’s Speech each year. While Parliament could legislate a different mechanism to end a session, they’re more likely to transform it from a prerogative power to a statutory power (if they do anything at all).
This would allow Parliament to set conditions for prorogation. The most realistic option would probably be a time limit (e.g., Parliament can only be prorogued for a maximum of 14 days). Alternatively, they could require the Commons (and maybe the Lords, too) to approve a proposed prorogation by passing a motion to that effect. That seems unlikely though, as this level of control seems unnecessary for something that is usually a routine matter.
So while prorogation’s days as a prerogative power may be numbered, it probably won’t disappear from parliamentary life.
