A cross-party group of UK MPs say migrants should learn English before coming to the UK, or attend language classes when they arrive. "The key to full participation in our society and economy" is to speak English, the group says. A recent report warned of "worrying" levels of segregation in some areas and calls for more English classes for isolated groups. The UK government has promised new migration controls after the UK leaves the EU, but has presented no details on it yet. According to the group, "substantial" immigration powers should be devolved to the UK's nations and regions.
