They don't decide on a recall. They can sanction an MP, such as suspension from the House of Commons.

Instead, a recall petition - requiring 10% of an MP's constituents to sign to then recall - is automatically triggered when an MP is suspended for 10 or more days.

This has happened e.g. in 2023 to Margaret Farrier - https://www.bbc.co.uk/news/uk-scotland-scotland-politics-663...

Her recall got nearly 15% of eligible voters which is about half as many votes as she got to win the seat in 2019. Thousands of locals came out solely to sack this MP.

Quick timeline: elected December 2019; spreading covid September 2020; guilty plea August 2022; loses seat July 2023 (10 months before the next general election)

		Notably, Binface got about 1500 more actual votes than that petition would need signatures, on a hot August day. The petition is published for six weeks! Farage must be very uncomfortable now.
