text: On 10 January 2011, ETA declared that their September 2010 ceasefire would be permanent and verifiable by international observers. Observers urged caution, pointing out that ETA had broken permanent ceasefires in the past, whereas Prime Minister José Luis Rodríguez Zapatero (who left office in December 2011) demanded that ETA declare that it had given up violence once and for all. After the declaration, Spanish press started speculating of a possible Real IRA-type split within ETA, with hardliners forming a new more violent offshoot led by "Dienteputo".
  On 21 October 2011, ETA announced a cessation of armed activity via video clip sent to media outlets following the Donostia-San Sebastián International Peace Conference, which was attended by former UN Secretary-General Kofi Annan, former Taoiseach of Ireland Bertie Ahern, former prime minister of Norway Gro Harlem Brundtland (an international leader in sustainable development and public health), former Interior Minister of France Pierre Joxe, president of Sinn Féin Gerry Adams (a Teachta Dála in Dáil Éireann), and British diplomat Jonathan Powell, who served as the first Downing Street Chief of Staff.
  They all signed a final declaration that was supported also by former UK Prime Minister Tony Blair, the former US president and 2002 Nobel Peace Prize winner Jimmy Carter, and the former US senator and former US Special Envoy for Middle East Peace George J. Mitchell. The meeting did not include Spanish or French government representatives.
