(I felt slightly dirty googling for a proxy - not something I've done in many years..)
I was weirdly annoyed by this actually, not sure why but as a British citizen I feel like I should/ am entitled to be able to view this content - especially seeing as when abroad I can still view the BBC new home page (albeit with ads)
Though if you leave the UK to view content the BBC will pay you a large severance fee...
I like to think they do this intentionally as a way of drawing attention to how absurd some of these rules are.
