This interesting comment piece in the Guardian makes the point that the Government's policy on immigration appears increasingly out of step with its commitment to tackle modern slavery. 

A report published recently by the Council of Europe's expert group on human trafficking (Group of Experts on Action against Trafficking in Human Beings - GRETA) has urged the UK to do more to tackle the issue. The report specifically urges the UK to implement its immigration policies in a manner that is compatible with its commitments under the anti-trafficking convention - most particularly the requirement to identify victims of trafficking and providing assistance to them.
