Zvonimir Boban resigns as UEFA technical director in protest at Aleksander Ceferin's attempt to stay on as president beyond the three-term limit.
Ceferin is seeking to amend the rule to remain in power until 2031, despite campaigning on a reform ticket that included a three-term limit.
Boban and other UEFA executives are critical of Ceferin's proposed changes, believing it goes against the values and principles of UEFA.
