Ukip leader Nigel Farage was rounded on by the politicians taking part in the TV election debate when he said that the treatment of foreigners with HIV was a burden on the health service.
The studio audience clapped enthusiastically when he said that the NHS should only be for people living in Britain.
In the days that followed the usual suspects added their vitriolic tuppence-worth against Farage.
Australia and New Zealand ban those with HIV and other expensive illnesses from entering their countries.
HIV drugs cost more than £25,000 a year and there are estimated to be 4,000 foreigners receiving treatment so that is £100 million every year.
Then there is health tourism from the rest of the world, with £62m outstanding or more correctly unrecoverable.
British cancer victims have been denied drugs that could extend their lives because they are too expensive but the usual let-everyone-in suspects remain silent.
