Whatever their need, I do think it's a huge cheek when state supported people think they can just choose a nicer place to live - at our expense. I'm sure many of us with mortgages would like to do this too. But we don't have that choice.
If you seriously think, Jaxhog, that people in council housing can just demand a nicer place to live in and will get it, you're incredibly naïve and need to educate yourself urgently.
Where does it say that this pair want a nicer place to live? So far as I can see, they simply need somewhere to live, full stop. It's news to me that people are clamouring to live in Barnet, it's hardly Knightsbridge or Mayfair.
