When Bishop Birinus died in 650, Cenwalh invited Agilbert, a Frankish monk to come to Wessex as the new bishop of Dorchester. But after some time Cenwalh grew tired of not being able to understand the bishop, who apparently did not speak the Anglo-Saxon language. Cenwalh created a new diocese at Winchester in 660 and made Wine the first bishop. Agilbert took offense at not being consulted and returned to Gaul. Wine was later expelled by Cenwalh and went to King Wulfhere of Mercia. Bede stated that Wine purchased the see (diocese) of London from Wulfhere. This left Wessex without a bishop. Cenwalh sent appeals to Agilbert to return to Wessex. Agilbert turned Cenwalh down saying his current duties as bishop of Paris prevented his return. But he sent his nephew Leutherius in his place. Cenwalh sent Leutherius to Theodore, Archbishop of Canterbury for consecration. Leutherius was welcomed in Wessex as the new bishop of Winchester.
