They are in France. A perfectly fine country.
Fine unless for example they speak English and have an established family in the UK. Is it better for anyone to have someone live a poor, excluded, disconnected and ultimately vulnerable life in France when they could be connected and productive in the UK? Europe’s asylum systems are a mess, it’s totally unacceptable to leave the Eastern fringes carrying the burden because the western states happen to have a buffer one side and a sea border the other (or a moat as for UK and Eire).
