“Once one recognises that the purpose of according to a worker a right permanently to reside in a EU state is that of encouraging the integration of such workers into the population of the host state and that such purpose is not achieved or achievable in prison, it must follow that the worker is not legally resident in the host state as an EEA worker during the period of imprisonment and that any period, which includes that period of imprisonment, cannot be part of the necessary “continuous” period for the purpose of calculating the five years continuous legal residence necessary to acquire the right permanently to reside here.”
