Ban affecting Sudan, Afghanistan, Myanmar and Cameroon will mean more people make Channel crossings, charity says

A new ban on students coming to the UK from four countries where there is war and human rights abuses will drive more people use small boats, campaigners have warned.

The home secretary, Shabana Mahmood, announced a bar on student visas from Sudan, Afghanistan, Myanmar and Cameroon on Tuesday evening. It will come into force on 26 March.
