Nigel Farage's comments on HIV patients have been defended by a Ukip MEP.
The Ukip leader prompted controversy while discussing so-called "health tourism", claiming that 60% of people diagnosed with HIV on the NHS were not British nationals.
The statement prompted criticism from other leaders, including Plaid Cymru's Leanne Wood, who told Farage he "should be ashamed" of himself.
However, Steven Woolfe, MEP for the north-west, told BBC Radio 4's Today programme: "Nigel is not saying that those people should not be treated now."
He said Farage was making the point that the NHS should not be "an international health service", and argued Barack Obama was not criticised despite the United States having provisions in place to stop foreign people accessing healthcare for free.
It is a question of whether we should be having an insurance policy for those people who are travellers, visitors, coming here as students, as happens in over a hundred countries across the world, including places like the United States or Canada.

Another day on the election trail and the campaign catchphrase is starting to bite.
Leaders' Debate shows was how our political horizon has suddenly changed as smaller parties did all they could to make themselves heard.
