All-Party Parliamentary Groups

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.

Register of APPGs

Groups which register as APPGs have to conform to rules about cross-party membership and transparency about their activities and funding. The Register of All-Party Parliamentary Groups is an authoritative list of such groups. A new edition of the register is usually published every 6 weeks approximately.

Registration Form for APPGs

Before being accepted on to the Register of APPGs a group must complete the Registration Form for APPGs (PDF PDF 242 KB)

Any prospective new group that is thinking of applying for inclusion on the Register should first contact the Office of the Parliamentary Commissioner for Standards, whose details are shown below.
