There was an influx of Italian immigrants to France and the UK just post - WW2. and for several years afterwards. My parents in NE England had Italian neighbours. They started the first ice-cream business in our town and did very well. I believe many settled in Glasgow. The Italians also opened restaurants all over the UK, leading to the popularity of pizzas these days. I think in southern France they became agricultural workers. In the late '50s I became friendly with a large group of young Italians when I did a summer vacation job in a London mental hospital. (They worked there, without a word of english!) I've often wondered why the situation was so bad in Italy postwar? I suppose it was the same all over Europe - people were still starving.
