International Democrat Union

The International Democrat Union, abbreviated to IDU, is a centre-right international alliance of conservative and liberal-conservative political parties. Headquartered in Oslo, Norway, the IDU comprises 45 full or associate members. It is chaired by John Howard, former Prime Minister of Australia.



The IDU provides a forum in which political parties holding similar beliefs can come together and exchange views on matters of policy and organisational interest. From this, they act cooperatively, establish contacts, and present a unified voice toward the promotion of centre-right policies across the globe. The IDU has some overlap of member parties with the Centrist Democrat International (CDI), but the CDI is more centrist and communitarian than the IDU.

The group was founded in 1983 as the umbrella organisation for the European Democrat Union (EDU), Caribbean Democrat Union (CDU), and the Pacific Democrat Union (PDU). Created at the instigation of the Konrad Adenauer Foundation and American Vice President George H. W. Bush, the organisation was founded at a joint meeting of the EDU and PDU in London, the United Kingdom.

The IDU has several regional affiliates: the Democrat Union of Africa, the Union of Latin American Parties, the Asia Pacific Democrat Union, the Caribbean Democrat Union, and both the European People's Party and European Democrat Union in Europe. It also has an affiliated youth wing in the International Young Democrat Union and an affiliated women's wing in the International Women's Democrat Union.
