About Us

PROGRESSIVE POLITICS for a fairer world

The Socialist International is the worldwide organisation of social democratic, socialist and labour parties. It currently brings together 152 political parties and organisations from all continents. (List of members in full)

A history of growth and accomplishment

The Socialist International, whose origins go back to the early international organisations of the labour movement, has existed in its present form since 1951, when it was re-established at the Frankfurt Congress. Since then it has been increasingly active and grown considerably in membership, more than doubling the number of its members in recent years. Labour, social democratic and socialist parties are now a major political force in democracies around the world, with numerous member parties of the International leading governments or representing the main opposition force. Currently 54 member parties of the International are in government.


The supreme decision-making bodies of the International are the Congress, which meets every four years, and the Council, which includes all member parties and organisations and which meets twice a year.

George A. Papandreou, former Prime Minister of Greece, is President of the Socialist International, first elected in January 2006, and re-elected at the XXIV Congress. Luis Ayala (Chile) is the Secretary General, re-elected at the last Congress. The Vice-Presidents, who are also elected by the Congress, together with the President and the Secretary General, make up the Presidium of the International, the leadership of the organisation. 

From 1976 to 1992 the late Willy Brandt, former Chancellor of Germany and winner of the 1971 Nobel Peace Prize, was President of the Socialist International. The late Pierre Mauroy, former Prime Minister of France, served as President from 1992 to 1999, and António Guterres, former Prime Minister of Portugal, from 1999 to 2005.

The secretariat of the Socialist International is located in London and coordinates the activities and initiatives of the International, convenes its meetings and conferences, issues statements and press releases and produces its publications.

Global and regional work of the Socialist International

The Socialist International works intensely throughout the year to strengthen and develop social democratic policies in the world, including through the activities of its thematic and regional Committees, Working Groups, and Commissions.

At the Council of Socialist International held in Portugal on 4-5 February 2013, the International established for this inter-Congress period, in addition to the statutory Ethics Committee and Committee for Finance and Administration, the organisation’s thematic and regional Committees, Working Groups and a new Commission on Equality.

Thematic Committees

With the purpose of deepening, broadening and promoting particular areas of global policy, the current thematic Committees of the Socialist International are the Committee on Democracy; the Committee on Local Government; the Committee on Poverty; and the Committee on Migrations. Each Committee sets a specific programme of activities and meets regularly.

Regional Committees

The regional Committees define and inform the work of the Socialist International with regard to their respective regions, and generate input from their national and regional perspectives to the common global policies of the organisation. The regional Committees of the Socialist International are the Africa Committee; the Committee on the Arab World; the Committee for Asia and the Pacific; the Committee for the CIS, the Caucasus and the Black Sea; the Committee on the Kurdish People; the Committee for Latin America and the Caribbean; the Mediterranean Committee; the Middle East Committee; and the Committee for South Eastern Europe.

Working Groups

Working Groups of the Socialist International are designed to target specific areas of importance that warrant greater research and scrutiny. The current Working Groups of the Socialist International are the Working Group on Accountability and Transparency; the Working Group on Political Education; the Working Group on Social Media; the Working Group on Individual Membership; and the Working group on Syria.

Previous Commissions

Commission for a Sustainable World Society

The SI Commission for a Sustainable World Society was established by the Socialist International to articulate from the world of progressive politics a way forward to address global environmental concerns, climate change and the issues of governance required to deal with these common challenges. The Commission brought together leading personalities, including serving and former heads of state and government ministers from different continents, to set out recommendations to tackle these fundamental issues, with a particular focus on supporting and contributing to the United Nations Climate Change Conferences and the global effort to reduce global warming.

Commission on Global Financial Issues

The SI Commission on Global Financial Issues was established by the Socialist International to address from a social democratic perspective the ongoing global financial crisis. The Commission brought together political leaders, ministers and noted experts from all continents who worked to formulate a global progressive response to the crisis based on the principles of democratic due process and full transparency and which were consistent with the values of social justice and social solidarity.

Missions and delegations

The Socialist International frequently sends missions and delegations to various countries and regions to help promote peaceful resolutions of conflicts and to support the strengthening of democracy, including through the observation of elections. In recent years such missions and delegations have visited on many occasions the Middle East, Africa, Latin America and the Caribbean, and Central and Eastern Europe.

Consultative status with the United Nations

As a non-governmental organisation, the Socialist International has consultative status (Category I) with the United Nations, and works internationally with a large number of other organisations.

Latest developments in Iraq and Syria

15 October 2014

The latest developments in Iraq and Syria continue to demonstrate that the terror carried out by ISIS is a major threat to international peace and security, to the people in the region and to the world at large, which must urgently be brought to an end. We reiterate the previous calls of the Socialist International for the international community to unite in response to this terror and to act in defence of the innocent populations of Iraq and Syria, and in support of those from all ethnic and religious groups affected.

Ending terror in Iraq and Syria

25 September 2014

From the headquarters of the United Nations in New York, where the international community has come together to stand against terror, the Socialist International recalled the declaration of the SI Council in Mexico City on 30 June-1 July 2014 on the insurgency in Iraq, which condemned the acts of the terrorist group Islamic State in Iraq and Syria (ISIS). The attacks perpetrated by ISIS have increased in their barbarism and the group now operates with disregard for national borders across areas of northern Iraq and Syria...

The Socialist International Committee for the CIS, the Caucasus and the Black Sea, meeting in Astana, Kazakhstan on 15-16 September 2014, addressed the issue of overcoming conflicts and securing peace in the region, paying particular attention to the current conflict in Ukraine.

SI calls for immediate ceasefire in the ongoing crisis in Gaza

14 July 2014

The Socialist International, deeply concerned about the ongoing crisis in Gaza and the increasing civilian death toll, urges both Israeli and Palestinian leaders to immediately de-escalate the crisis, to restore calm and re-establish the ceasefire of November 2012, as called for by the Security Council of the United Nations on 12 July. The respect for humanitarian law, and in particular the protection of civilians, is fundamental, as the loss of life and the suffering that the world has witnessed in the past days is totally unacceptable...


Socialist International condemns shelling of refugee shelter in Gaza

24 JULY 2014

Socialist International condemns unreservedly the assault by the Israeli Defence Force against a school used by the United Nations Relief and Works Agency (UNRWA) as a shelter in northern Gaza harbouring refugees, mostly women and children, killing at least fifteen and leaving hundreds injured. Reports from UNRWA officials highlight that great efforts had been made to secure a window so that civilians could evacuate to safety but these efforts were to no avail. For over seven years the citizens of Gaza have had to endure hardship and suffering brought about by Israel’s blockade of the enclave....

04 JUNE 2014

The President of the Socialist International, George Papandreou, during a working visit to Jordan, was received on Monday 2nd of June, in Amman, by His Majesty the King Abdallah II. The King reviewed the repercussions of the crisis in Syria on neighbouring countries, mainly on Jordan.

Venezuela : for an end to the violence

17 February 2014

The situation in Venezuela continues to be of serious concern for the international community. That in a democracy violence can reach the levels observed last week in Caracas and in other places of the country with people being killed and injured, opposition leaders being persecuted, with restrictions on freedoms, including the freedom of information, amongst others, point to the gravity of the situation in that country...


Ending the stalemate in Cyprus

17 February 2014

The agreement between the President of the Republic of Cyprus Nicos Anastasiades and the Turkish Cypriot leader Dervis Eroglu on a Joint Statement is opening the way for renewed negotiations and provides a solid basis for a constructive dialogue that can lead to a functional and viable resolution of the Cyprus problem as soon as possible. It also creates the conditions for ending, at last, the unacceptable status quo...

11 February 2014

Sushil Koirala got the support of 405 of the 553 members of parliament that took part in the vote. The NCP will now have again, after its last time in office in 2006-2008 under the late G. P. Koirala, the opportunity to bring forward its social democratic agenda and to strengthen the institutional framework of Nepal...


For an Olympic Truce in Syria during the Sochi Games


07 FEBRUARY 2014

Ahead of the second round of Geneva II talks, and following the agreement on the removal of the country’s chemical weapons, our priority in Syria must now be to address the ongoing humanitarian crisis. According to available estimates, more than 130,000 people have been killed since March 2011. Millions more have been displaced as refugees. Securing a ceasefire would provide immediate relief for citizens caught in the fighting and enable humanitarian aid to reach those in need…
