Strange Goose? Hybird

Observation - Strange Goose? Hybird - UK and Ireland. Description: I think it is a mix/hybird of some sort. Was on its own when photo was taken. though i have seen it hang around with graylags. White front, but then the white carries on down the back of its head. Pink beak and feet. Any ideas?
