I think the conclusion is that Mark Thatcher has had a fair few residencies over the years, and it looks like in a fair few the local milkman is still owed some cash. It's a bit of a travesty that a knight of the realm can have such a chequered past, but hey, thats business !
A little bit of background for you on this, it is only Wikipedia so it may have some small inaccuracies but I would assume most is pretty valid.
Enjoy !
