Karl Lehmann retires

Cardinal Karl Lehmann has retired as bishop of Mainz.

Lehmann is a former chairman of the German Bishops' Conference.

He was ordained a priest in 1963 by Julius Döpfner and was an assistant to Karl Rahner.

He is considered a leading German theologian and over the years has had 'quarrels' with the Vatican.

On one occasion he was critical of how 'anonymous' people had influence in the appointment of bishops.

Jürgen Klopp, manager of Liverpool FC, paid tribute to Cardinal Lehmann on this evening's ZDF news.
