The departure of Ieuan Wyn Jones from the Assembly marks the end of a lengthy political career that often defied expectations. Despite a challenge which curtailed his leadership in 2003, he went on to regain overall control of Plaid Cymru and took the party into government with Labour in 2007.
Most agree that that first taste of government for Plaid and the achievement of a referendum which gave the Assembly lawmaking powers will form Ieuan Wyn Jones' legacy. He didn't have the charisma of leaders like Gwynfor Evans, Dafydd Elis-Thomas and Dafydd Wigley but he took his party into power.
A party strategist since he led Plaid Cymru's internal inquiry into the setbacks of 1979, Ieuan Wyn Jones emerged to snatch Ynys Mon at the 1987 General Election. Plaid lost the Westminster seat when he stood down from Parliament. Now it must defend the Assembly seat without him.
