The Queen is Head of the Commonwealth, a voluntary association of 53 independent countries.

From Antigua to Zambia, the Commonwealth is a remarkable international organisation, spanning every geographical region, religion and culture. It exists to foster international co-operation and trade links between people all over the world.

Some countries within the Commonwealth have The Queen as their Sovereign, whilst remaining independent in the conduct of their own affairs. They are known as Commonwealth realms.

The Queen and the Royal Family retain close links with the Commonwealth realms, and with other members of the worldwide Commonwealth organisation.
