In 1957, after both proposals had been rejected, France signed the Treaty of Rome with West Germany and the other founding nations of the Common Market, later to become the European Union, which the United Kingdom joined in 1973. Malta and Cyprus, also Commonwealth members, joined in 2004.
In recent years, the Commonwealth has suspended several members "from the Councils of the Commonwealth" for "serious or persistent violations" of the Harare Declaration, particularly in abrogating their responsibility to have democratic government. This is done by the Commonwealth Ministerial Action Group (CMAG), which meets regularly to address potential breaches of the Harare Declaration. Suspended members are not represented at meetings of Commonwealth leaders and ministers, although they remain members of the organisation. Currently, there is one suspended member, Fiji.
Nigeria was suspended between 11 November 1995 and 29 May 1999, following its execution of Ken Saro-Wiwa on the eve of the 1995 CHOGM. Pakistan was the second country to be suspended, on 18 October 1999, following the military coup by Pervez Musharraf. The Commonwealth's longest suspension came to an end on 22 May 2004, when Pakistan's suspension was lifted following the restoration of the country's constitution. Pakistan was suspended for a second time, far more briefly, for six months from 22 November 2007, when Musharraf called a state of emergency. Zimbabwe was suspended in 2002 over concerns with the electoral and land reform policies of Robert Mugabe's ZANU-PF government, before it withdrew from the organisation in 2003.
Fiji, which was not a member of the Commonwealth between 1987 and 1997 as a result of two coups d'état, has been suspended twice, with the first imposed from 6 June 2000 to 20 December 2001 after another coup. Fiji has been suspended again since 8 December 2006, following the most recent coup. At first, the suspension applied only to membership on the Councils of the Commonwealth. After failing to meet a Commonwealth deadline for setting a date for national elections by 2010, Fiji was "fully suspended" on 1 September 2009. The Secretary-General of the Commonwealth, Kamalesh Sharma, confirmed that full suspension meant that Fiji would be excluded from Commonwealth meetings, sporting events and the technical assistance programme (with an exception for assistance in re-establishing democracy). Sharma also stated that Fiji would remain a member of the Commonwealth during its suspension, but would be excluded from emblematic representation by the secretariat.
Most recently, international pressure has been mounting to suspend Sri Lanka from the Commonwealth and to change the 2013 Commonwealth Heads of Government Meeting (CHOGM) from Sri Lanka to another member country, citing grave human rights violations by the host country. Canadian prime minister Stephen Harper has threatened to boycott the event and the UK Foreign Affairs Committee has also called upon Prime Minister David Cameron not to attend.
As membership is purely voluntary, member governments can choose at any time to leave the Commonwealth. Pakistan left on 30 January 1972 in protest at the Commonwealth's recognition of breakaway Bangladesh, but rejoined on 2 August 1989. Zimbabwe's membership was suspended in 2002 on the grounds of alleged human rights violations and deliberate misgovernment, and Zimbabwe's government terminated its membership in 2003.
Although heads of government have the power to suspend member states from active participation, the Commonwealth has no provision for the expulsion of members. Until 2007, Commonwealth realms that became republics automatically ceased to be members, until (like India in 1950) they obtained the permission of other members to remain in the organisation. This policy has been changed, so if any current Commonwealth realms were to become republics, they would not have to go through this process. Ireland left the Commonwealth when it declared itself a republic, on 18 April 1949, after enacting the Republic of Ireland Act 1948.
South Africa was prevented from continuing as a member after it became a republic in 1961, due to hostility from many members, particularly those in Africa and Asia as well as Canada, to its policy of apartheid. The South African government withdrew its application to remain in the organisation as a republic when it became clear at the 1961 Meeting of Commonwealth Prime Ministers that any such application would be rejected. South Africa was re-admitted to the Commonwealth in 1994, following the end of apartheid earlier that year.
The declaration of a republic in Fiji in 1987, after military coups designed to deny Indo-Fijians political power, was not accompanied by an application to remain. Commonwealth membership was held to have lapsed until 1997, after discriminatory provisions in the republican constitution were repealed and reapplication for membership made.
The Transfer of sovereignty over Hong Kong in 1997 ended the colony's ties to the Commonwealth through the United Kingdom. The government of Hong Kong, as a special administrative region of China, did not pursue membership. Hong Kong SAR has nevertheless continued to participate in some of the organisations of the Commonwealth family, such as the Commonwealth Lawyers Association, the Commonwealth Parliamentary Association, the Association of Commonwealth Universities and the Commonwealth Association of Legislative Counsel.
Commonwealth countries share many links outside government, with over a hundred Commonwealth-wide non-governmental organisations, notably for sport, culture, education, law and charity. The Association of Commonwealth Universities is an important vehicle for academic links, particularly through scholarships, principally the Commonwealth Scholarship, for students to study in universities in other Commonwealth countries. There are also many non-official associations that bring together individuals who work within the spheres of law and government, such as the Commonwealth Lawyers Association and the Commonwealth Parliamentary Association.
The Commonwealth Foundation is an intergovernmental organisation, resourced by and reporting to Commonwealth governments, and guided by Commonwealth values and priorities. Its mandate is to strengthen civil society in the achievement of Commonwealth priorities: democracy and good governance, respect for human rights and gender equality, poverty eradication and sustainable, people-centred and sustainable development, and to promote arts and culture.
The Foundation was established by the Heads of Government in 1965. Admittance is open to all members of the Commonwealth and in December 2008 stood at 46 out of the 54 member countries. Associate Membership, which is open to associated states or overseas territories of member governments, has been granted to Gibraltar. 2005 saw celebrations for the Foundation's 40th Anniversary. The Foundation is headquartered in Marlborough House, Pall Mall, London. Regular liaison and cooperation between the Secretariat and the Foundation is in place.
The Foundation continues to serve the broad purposes for which it was established as written in the Memorandum of Understanding.
The Commonwealth Games, a multi-sport event, is held every four years; the 2010 Commonwealth Games were held in New Delhi, India in 2010, and the next in Glasgow, Scotland in 2014. As well as the usual athletic disciplines, as at the Summer Olympic Games, the games include sports particularly popular in the Commonwealth, such as bowls, netball, and rugby sevens. Started in 1930 as the Empire Games, the games were founded on the Olympic model of amateurism, but were deliberately designed to be, as they are still renowned for being "the Friendly Games", with the goal of promoting relations between Commonwealth countries and celebrating their shared sporting and cultural heritage.
The Games are the Commonwealth's most visible activity, and interest in the operation of the Commonwealth increases greatly when the Games are held. There is controversy over whether the Games – and sport generally – should be involved in the Commonwealth's wider political concerns. The 1977 Gleneagles Agreement was signed to commit Commonwealth countries to combat apartheid through discouraging sporting contact with South Africa (which was not then a member), whilst the 1986 Games were boycotted by most African, Asian, and Caribbean countries for the failure of other countries to enforce the Gleneagles Agreement.
The Commonwealth War Graves Commission (CWGC) is responsible for maintaining the war graves of 1.7 million service personnel that died in the First and Second World Wars fighting for Commonwealth member states. Founded in 1917, the Commission has constructed 2,500 war cemeteries, and maintains individual graves at another 20,000 sites around the world. The vast majority of the latter are civilian cemeteries in Great Britain. In 1998, the CWGC made the records of its buried online to facilitate easier searching.
Commonwealth war cemeteries often feature similar horticulture and architecture, with larger cemeteries being home to a Cross of Sacrifice and Stone of Remembrance. The CWGC is notable for marking the graves identically, regardless of the rank, country of origin, race, or religion of the buried. It is funded by voluntary agreement by six Commonwealth members, in proportion to the nationality of the casualties in the graves maintained, with three-quarters of the funding coming from Britain.
The Commonwealth of Learning (COL) is an intergovernmental organisation created by the Heads of Government to encourage the development and sharing of open learning/distance education knowledge, resources and technologies. COL is helping developing nations improve access to quality education and training.
The Commonwealth Business Council (CBC) was formed at 1997 CHOGM. The aim was to utilise the global network of the Commonwealth more effectively for the promotion of global trade and investment for shared prosperity.
The CBC acts as a bridge for co-operation between business and government, concentrating efforts on these specific areas enhancing trade, facilitating ICT for Development, mobilising investment, promoting corporate citizenship, and public private partnerships. The CBC has a dedicated team, CBC Technologies, based in London and is focused on the international technology and global services industry throughout the Commonwealth.
Mostly due to their history of British rule, many Commonwealth nations possess traditions and customs that are elements of a shared Commonwealth culture. Examples include common sports such as cricket and rugby, driving on the left, the Westminster system of parliamentary democracy, common law, widespread use of the English language, designation of English as an official language, military and naval ranks, and the use of British rather than American spelling conventions (see English in the Commonwealth of Nations). None of these is universal among, nor exclusive to, the Commonwealth, but are more commonly found within its members than elsewhere.
