All-party groups are regarded as relatively informal compared with other cross-party bodies such as select committees of the House. The membership of all-party groups mainly comprises backbench Members of the House of Commons and Lords but may also include ministers and non-parliamentarians. Groups flourish and wane according to the interests and enthusiasm of Members.
Groups are classified either as subject groups (relating to a particular topic eg. forestry) or country groups (relating to a particular country or region). Most country groups are affiliated to the Commonwealth Parliamentary Association's United Kingdom Branch and/or the Inter-Parliamentary Union's British Group.
