[5] In January 2007, he was briefly detained after refusing to identify himself to police officers when a group of Jarrai supporters were arrested, but was released without charge shortly afterwards.

[3][8] In 2012 he was a candidate in the regional elections for EH Bildu, in the same constituency as previously of Álava, whilst still technically released on bail from the October 2007 incident.

[11] On 23 February 2013 the Constituent Assembly of Sortu chose Arraiz as the first president of the party at their founding conference; he was the only candidate presented.

[15] He later opened the door to other organisations, such as unions and social movements, to join what he called an "accumulation of democratic forces" to put into effect a process to realise "the rights of the Basque Country as a nation".

[23] In May 2016 he was banned by a judge from holding public office for his relationship with Batasuna, but avoided a prison sentence, after admitting having been a member of the ETA and apologising to its victims during the trial.

[24] After leaving the Basque Parliament in May 2016, he left the leadership of Sortu during their process of "re-foundation" in July 2016, at which point the position of president was abolished.
