Mr Blair is wrong about cul-de-sacs and he should think again. I love mine. It is along a narrow street in west London with a communal garden at one end and a church at the other. My loop is not packed with fatties. Mothers get their exercise by running up and down the quiet street teaching their children to ride their bicycles while fathers show off their footballing skills at the weekend.

In today's Telegraph, Alice Thomson writes in defense of the cul-de-sac. More community. Less traffic. Nice piece.
