From Hollande (French premier) today;
"“None can be separated from the other. There cannot be freedom of movement of goods, free movement of capital, free movement of services if there isn’t a free movement of people … It will be a choice facing the UK – remain in the single market and then assume the free movement that goes with it or to have another status.”"

"Hollande became the first EU leader to guarantee that British people living in France would be allowed to stay in his country once the UK’s exit negotiations conclude.

“There is no doubt that the French people who reside in the UK will be able to continue to work there and that the British people in France will be able to continue to work there and spend as much time as they wish,” he said."
