As well as taking part in formal parliamentary business, MPs are active in other areas such as within their own political parties and constituencies. They may also take part in informal work at Westminster, such as working with All-Party Parliamentary Groups (APPGs).
APPGs are informal cross-party groups that have no official status within Parliament. They are run by and for Members of the Commons and Lords, though many choose to involve individuals and organisations from outside Parliament in their administration and activities.
The APPG on Yemen is one of the most active in Parliament, regularly organising well-attended meetings with high-profile stakeholders and political figures, and organising debates to be held in the House of Commons.
