In 2006, the new Prime Minister of Kosovo, Agim Çeku, asked the British Government for help in developing and running his office. Because of his Whitehall experience and knowledge of the Balkans, Wilton was sent. He advised Çeku on international relations, communications and administration, accompanying the Prime Minister as his assistant in the 2007 Troika talks with Serbia. Wilton also worked for a short while under Prime Minister Hashim Thaçi. He was in Kosovo for the country's independence in February 2008. In 2010 he returned to Kosovo as Head of Policy and Political Affairs in the International Civilian Office, monitoring and advising the Kosovo Government. In 2013 he was appointed Deputy Ambassador of the Organization for Security and Co-operation in Europe (OSCE)'s Presence in Albania.
