A “LAZY, misguided and sloppy” David Cameron threatened yesterday to deport Muslim women who don’t improve their English, claiming they were easy prey for Islamic State (Isis) extremism.

The Prime Minister limply stated there was no “causal connection” between language and terrorism before warning that the 40,000 women in Britain who do not speak English — and 190,000 whose English is very poor — are “more susceptible” to the group’s message.

Women arriving in Britain on spousal visas are expected to have English skills at A1 level, equivalent to a native speaker starting primary school, but would need to reach A2 level within two-and-a-half years under his proposals.
