Plenary meetings are attended by all Members of the Senedd and provide one of the key mechanisms for Members to hold the Welsh Government and Senedd Commission to account, make laws for Wales and represent their constituents.

About the Siambr

Plenary meetings take place in the Siambr, the Senedd's debating chamber, each Tuesday and Wednesday afternoon. Plenary meetings usually begin at 13.30 and are always held in public.

Early Plenary Business following a Senedd Election

In the early days of a Senedd, Members must meet in Plenary to agree a number of key items of business. This includes the election of the Presiding Officer and Deputy and nominations for a First Minister.

Organisation of Plenary business

The topics discussed in Plenary meetings are organised by the Business Committee and announced on a weekly basis in Plenary. A Plenary Agenda is published for every meeting.

Types of Plenary business

Different categories and types of business can be taken in Plenary. These include questions, debates, statements and legislative proceedings.

Conduct in Plenary meetings
The rules outlining how Senedd proceedings should be conducted – the “Standing Orders” – require Members to behave in an appropriate manner at all times in the Siambr. As chairs of Plenary meetings, the Presiding and Deputy Presiding Officer are responsible for maintaining order.
