In 2003 he returned to the Institute of Social Studies as professor theory and practice of development cooperation. Pronk still holds several posts in Dutch civil society. In 2004 he came into conflict with minister Verdonk (Migration & Integration), because he characterized the way she sent asylum-seekers out of the country as "deportation". In June 2004 Pronk was appointed UN Special Representative for Sudan by United Nations Secretary-General Kofi Annan On September 21, 2006, Pronk asked the warring parties in Darfur, including President Omar al-Bashir and the seven rebel movements, to observe a "month of tranquility" during Ramadan, which would begin September 23, 2006. His implicit call for a ceasefire in the western region of Sudan came after the Khartoum government withdrew its ultimatum for African Union peacekeepers to pull out. Other African states then agreed to extend their mandate until the end of 2006. By Pronk's request, they would finish the collision course, which would mean no fighting, no bombing, no changes of heart. Such a lull would help "create an atmosphere" for a new round of negotiations. The peace deal was "in a coma": not dead but dying. In addition the rejectionist factions should end the quarrel to start talking about everything related to the Darfur peace agreement to improve it. In mid-October 2006, the army of Sudan accused Pronk of "waging psychological warfare on the armed forces" and demanded his deportation after Pronk published thoughts on army military defeats in his weblog. On 22 October, the Sudanese government gave Pronk three days' notice to leave the country. He left Sudan the next day (October 23) when UN Secretary General Kofi Annan recalled him to New York for consultations. On October 27 the UN Security Council and UN Secretary General Kofi Annan announce that Pronk will serve out his last months as Special Representative of the Secretary-general in Sudan. Pronk's story roughly parallels that of Mukesh Kapila, a previous UN employee who was forced to leave Sudan after making critical comments about the Darfur conflict. Labour Party (2007–2013) Jan Pronk was a candidate for the election of the chairman of the Dutch Labour Party (PvdA). As a candidate he wanted the party to return to a more leftwing course. He lost the election, between September 16 and September 23, 2007, to Lilianne Ploumen. On 28 May 2013, Jan Pronk publicly announced he is ending his membership of the
