The desperate, brave faces of Europe's secret immigration crisis

We are ignoring a European crisis that is going to change all our lives irreversibly and for ever. It is the huge, tragic surge of African migrants across the Mediterranean.

Once inside the borderless European Union, these newcomers can and will settle anywhere. There is no law or power that can stop them.

I first became aware of this when I went to Ceuta, a Spanish enclave in North Africa. I had gone to tease Spain for moaning about Gibraltar, while it had its own Gibraltar in Morocco.

But much more serious was the virtual siege of Ceuta (and its nearby twin, Melilla) by migrants, immense numbers of them, crowding up against the 20ft fences which are all that separate this little piece of Spain from Africa.
