Tunis — Caretaker President Moncef Marzouki, Sunday, left Tunis for the United Kingdom on a three-day working visit.

The visit comes after the decision of the UK Royal Institute of International Affairs to award the "Chatham House" Prize 2012 to President Marzouki and President of "Ennahdha" Movement Rached Ghannouchi.

President of the Institute Robin Niblett had told the media after the announcement of the results that Messrs. Marzouki and Ghannouchi are joint winners for the successful compromises each achieved during Tunisia's democratic transition.

Representing two sides of the same coin, they have together ensured that Tunisia remains at the forefront of the new democratic wave in the Middle East and North Africa, he added.

President Marzouki, who was accompanied by Secretary of State for American and Asian Affairs Hedi Ben Abbes, will meet during this visit President of the UK House of Commons John Bercow, Charles, Prince of Wales and several MPs.

Marzouki will also address the House of Commons and the Royal Institute of International Affairs.
