This would mean that only heart disease and cancer killed more people than the very people trying to treat these diseases.  But there are good reasons to be suspicious about the claim.

Are these claims fair? We give some needed context.  Net migration has fallen - we talk to someone who predicted it would - Dr Madeleine Sumption, director of the Migration Observatory at the University of Oxford.  Is Taylor Swift about to add £1 bn to the British economy as some media outlets have claimed? The answer is ‘No’.  Why are our prisons full? We ask Cassia Rowland from the Institute for Government.
